The purpose of this study is to examine the associations among different quality management (QM) practices and investigate which QM practices directly or indirectly relate to five types of innovation: radical
product, radical process, incremental product, incremental process, and administrative innovation. We
test the proposed framework and hypotheses using empirical data from ISO 9001 certified manufacturing
and service firms. The results show that a set of QM practices through process management has a positive
relationship with all of these five types of innovation. It was found that process management directly
and positively relates to incremental, radical, and administrative innovation. Organizational capability
to manage processes may play a vital role in identifying routines, establishing a learning base, and supporting innovative activities. The findings also reveal that the value of an individual QM practice is tied to
other QM practices. Therefore, highlighting just one or a few QM practices or techniques may not result
in creative problem solving and innovation.

1. Introduction
Over the last 30 years, innovation has caught the attention of
researchers and practitioners (Gatignon et al., 2002; Damanpour,
1987). In a turbulent economic environment, innovation is a strategic driver in seizing new opportunities and protecting knowledge
assets (Hurmelinna-Laukkanen et al., 2008; Teece, 2000). Specifically, innovation plays a key role in providing unique products and
services by creating greater value than was previously recognized
and establishing entry barriers (Lloréns Montes et al., 2005). The
importance of innovation has motivated researchers to identify the
various driving forces of innovation (Becheikh et al., 2006). Some
researchers contend that quality management (QM) could be one of
the prerequisites of innovation (Hoang et al., 2006; Perdomo-Ortiz
et al., 2006). QM practices contribute to operational and financial
performance, allowing a firm to achieve a competitive advantage
(Lagrosen and Lagrosen, 2005; Kaynak, 2003). It is not surprising
that many manufacturing and service firms around the world (e.g.,
Xerox, Ford, Motorola, and Federal Express) have adopted QM over
the last two decades (Rahman, 2004; Powell, 1995).
Since the early 2000s, researchers have conducted empirical
studies on the relationship between QM and innovation. While

previous studies have provided interesting insight into the role of
QM practices in innovation, a few shortcomings in these studies
emerge from the literature review. First of all, earlier studies failed
to explain which QM practices are directly or indirectly associated
with innovation. Most studies examined only the direct relationship between QM practices and innovation. Researchers have
tended to identify whether the implementation of QM practices
is positively related to innovation (e.g., Abrunhosa et al., 2008;
Martinez-Costa and Martinez-Lorente, 2008; Hoang et al., 2006)
or which QM practice is directly related to innovation (Moura
et al., 2007; Prajogo and Sohal, 2004). Second, researchers were
limited to assessing only a few types of innovation. Some studies
examined a single type of innovation, such as process innovation
(e.g., Abrunhosa et al., 2008) or product innovation (e.g., Prajogo
and Sohal, 2004), whereas others explored both process and
product innovation (e.g., Feng et al., 2006; Martinez-Costa and
Martinez-Lorente, 2008). Looking at the earlier studies, two questions arise: Is it worthwhile to examine QM practices that can lead
to only product and process innovations? If not, what other types
of innovation should be explored to clearly address an association
between QM and innovation? These studies devoted only limited
attention to examining various types of innovation. This narrow
view of innovation may be a barrier that causes a misunderstanding of the contribution of QM to innovation. The multidimensional
types of innovation need to be tested to correctly understand
the real value of QM on innovation. Third, earlier studies on the
relationship between QM and innovation have provided inconsistent findings (See Appendix A). Some found that QM practices
are positively related to innovation (e.g., Perdomo-Ortiz et al.,
296
D. Y. Kim et al. / Journal of Operations Management 30 (2012) 295–315
2006; Martinez-Costa and Martinez-Lorente, 2008), whereas others concluded that there is no evidence linking QM activities and
innovation (e.g., Singh and Smith, 2004; Moura et al., 2007; Prajogo
and Sohal, 2004; Santos-Vijande and Álvarez-González, 2007).
This study explores the following two questions: What relationship exists among QM practices? Which QM practices are
directly or indirectly related to innovation? We concentrate on
the research questions by conducting an empirical study of manufacturing and service firms. The objective of this study is to
empirically investigate the relationships among QM practices and
to explore which QM practices are directly or indirectly associated with five types of innovation: radical product, radical process,
incremental product, incremental process, and administrative. The
remainder of this study is organized as follows. The following
section describes the extant literature, gives a research model,
and presents hypotheses. The next section presents methodology,
including data collection, measurement scales, measurement analysis, and hypothesis testing. Finally, this study concludes with a
discussion, notes the implications of the results, and gives suggestions for future research.
organization to be a system of interlocking processes. The research,
called linkage-oriented research, mainly tests associations among
QM practices (Sila and Ebrahimpour, 2005). The linkage-oriented
research relies on sophisticated analysis techniques, such as structural equation modeling, path analysis, and partial least square
method (e.g., Flynn et al., 1995; Ravichandran and Rai, 2000)
because the research mainly includes a complex research model
with many variables. Actually, researchers have provided mixed
findings on the relationships among QM practices. We, however, find two common views in the literature. The first view is
that the successful implementation of QM can be attributed to
the strong support of a combination of a series of practices, not
just a few practices separately (Ravichandran, 2007; Nair, 2006;
Schendel, 1994; Douglas and Judge, 2001). The second view is
that QM practices could lead to improved performance in areas
such as quality, operations, innovation, and business results (Flynn
et al., 1995; Ravichandran and Rai, 2000; Hoang et al., 2006;
Kaynak, 2003). We regard these views as basic assumptions in this
study.
2.2. Classification of innovation
2. Theoretical background and hypotheses
This section discusses four topics: QM practices, classification
of innovation, the relationship between QM and innovation, and a
research model.
2.1. QM practices
QM is a holistic management philosophy that fosters all functions of an organization through continuing improvement and
organizational change (Kaynak and Hartley, 2005). QM captures
features from distinct organizational models and extends them by
offering principles, methodologies, and techniques (Spencer, 1994).
Researchers emphasize that it is necessary for firms to define and
develop QM practices that can assist a multi-dimensional management philosophy. QM practices refer to critical activities that are
expected to lead, directly or indirectly, to improved quality performance and competitive advantage (Flynn et al., 1995).
Much attention in the research has been devoted to developing measurement constructs of QM and examining the association
between QM practices and performance. Saraph et al. (1989) provide the first attempt to explore the measurement of QM practices
(Perdomo-Ortiz et al., 2006). Their motivation is fuelled by the lack
of a systematic attempt to organize a set of QM practices and the
need to develop measures of the overall QM efforts in the literature. Using a survey of 162 general managers and quality managers,
they propose and test eight critical factors of QM: the role of management leadership, the role of the quality department, training,
employee relations, quality data and reporting, supplier quality
management, product/service design, and process management.
Similarly, Flynn et al. (1994), in their survey of 716 respondents,
argue that QM studies on theory development and measurement
failed to yield conclusive evidence related to validity and reliability.
They suggest seven key dimensions of QM and scales: top management support, quality information systems, process management,
product design, workforce management, supplier involvement, and
customer involvement. Although there is little agreement on the
list of QM practices (Samson and Terziovski, 1999), the efforts to
develop a set of QM practices provide a theoretical foundation to
scientifically connect traditional QM philosophies with practical
activities.
The existing empirical research on the relationship between
QM practices and performance is characterized by examinations
of the interdependent nature of QM practices. Researchers view an
Innovation refers to new applications of knowledge, ideas,
methods, and skills that can generate unique capabilities and leverage an organization’s competitiveness (Andersson et al., 2008; Daft,
1978). This definition reflects a broader view of innovation by covering both administrative and technological innovation. In a global
market, firms should have the ability to identify new chances,
and to reconfigure and shield technologies, competences, knowledge assets, and complementary assets to accomplish a sustainable,
competitive advantage (Teece, 2000). It is necessary to understand
a type of innovation and its different features, because a specific type of innovation requires an organization to demonstrate
unique and sophisticated responses. Researchers have explored
the classification of innovation in different ways. Although previous studies have proposed various classifications of innovation,
we found that empirical studies on innovation have explored five
types of innovation: incremental product, incremental process,
radical product, radical process, and administrative (e.g., Salavou
and Lioukas, 2003; Di Benedetto et al., 2008; Herrmann et al.,
2007; Vermeulen, 2005; Chandy and Tellis, 1998). We argue that
investigating the various types of innovation helps practitioners
break down their overall strategies on innovation into a particular type of innovation area and efficiently allocate resources for a
specific type of innovation. Thus, our study applies the five types
of innovation to analyze correlations with QM practices. In order
to distinguish the five types of innovation, we need to discuss
the differences between administrative and technological innovation; incremental and radical innovation; and product and process
innovation.
Innovation is first split into administrative and technological
innovation. Administrative innovation refers to the application of
new ideas to improve organizational structures and systems, and
processes pertaining to the social structure of an organization
(Weerawardena, 2003; Damanpour, 1987). In contrast, technological innovation is defined as the adoption of new technologies
that are integrated into products or processes (Yonghong et al.,
2005). Administrative innovation is often triggered by internal
needs for structuring and coordination, while technological innovation mainly responds to environmental factors, such as uncertain
market conditions or technical knowledge (Daft, 1978; Gaertner
et al., 1984). Administrative innovation uses a top-down approach
where upper level managers commit to relevant activities, whereas
technological innovation applies a bottom-up approach where
lower level technicians are involved (Daft, 1978). Administrative innovation requires considerable set-up costs and entails
D. Y. Kim et al. / Journal of Operations Management 30 (2012) 295–315
organizational disruption, influencing basic work activities directly
and customers indirectly (Weerawardena, 2003). A specialized
agency (e.g., a consulting firm) diffuses administrative innovation (Teece, 1980), while intellectual property laws (e.g., patents
or trademarks) protect technological innovation (Hoffman and
Hegarty, 1993). Depending on the degree and subject of innovation, technological innovation is further classified into incremental
and radical innovation, and product and process innovation.
Technological innovation can be divided into incremental and
radical innovation when considering the following features of innovation: the level of change (minor vs. major), a target customer
or market (existing vs. new), and the level of risk (low vs. high).
Incremental innovation refers to minor changes of existing technologies in terms of design, function, price, quantity, and features
to meet the needs of existing customers (Garcia and Calantone,
2002; De Propris, 2002), while radical innovation is defined as the
adoption of new technologies to create a demand not yet recognized by customers and markets (Jansen et al., 2006). Incremental
innovation focuses on refining, broadening, enhancing, and exploiting current knowledge, skills, and technical trajectory (Gatignon
et al., 2002), while radical innovation, regarded as competencedestroying (Teece et al., 1997), concentrates on market pull or
technology push strategies (Li et al., 2008). Incremental innovation
entails a low level of risk but provides fewer benefits (Koberg et al.,
2003); by contrast, radical innovation requires great uncertainty
and a high level of risk (Moguilnaia et al., 2005). A study found that
radical innovation covers only 10% of all new innovation, whereas
the proportion of incremental innovation is about 90% (Rothwell
and Gardiner, 1988).
It is important for a firm to decide which subject should receive
innovation for a new market position. The innovation subject is
either a product or a process. Product innovation refers to changes
at the end of providing products or services, while process innovation is defined as changes in the method of producing products
or services (De Propris, 2002). When we consider both the degree
and the subject of innovation, product innovation can be classified
into radical product innovation and incremental product innovation (Reichstein and Salter, 2006; Huiban and Bouhsina, 1998).
Radical product innovation is defined as innovation associated with
the introduction of products (or services) that incorporate substantially different technology from that now in use for existing
products, whereas incremental product innovation refers to innovation related to the introduction of products (or services) that
provide new features, improvements, or benefits to existing technology in the existing market (Chandy and Tellis, 1998; Herrmann
et al., 2007; Valle and Vázquez-Bustelo, 2009).
Process innovation is described as changes in the way that
an organization produces products or services (Koberg et al.,
2003; Utterback, 1994). Process innovation is associated with the
sequences and nature of the production process that improves
the productivity and the efficiency of production activities (Garcia
and Calantone, 2002; De Propris, 2002). Process innovation aims
to introduce a new element in production materials, machinery,
equipment, processes, task specifications, and workflow mechanisms (Damanpour, 1991). When reflecting both the degree and
the subject of innovation, we classify process innovation into two
types: radical process innovation and incremental process innovation (Reichstein and Salter, 2006). Radical process innovation refers
to innovation associated with the application of new or significantly
improved elements into an organization’s production or service
operations with the purpose of accomplishing lower costs and/or
higher product quality. In contrast, incremental process innovation
is identified as innovation associated with the application of minor
or incrementally improved elements into an organization’s production or service operations with the purpose of achieving lower
costs and/or higher product quality (Reichstein and Salter, 2006;
297
Ettlie, 1983; Gatignon et al., 2002). Table 1 provides an overview of
features and differences of the five types of innovation.
2.3. The relationship between QM and innovation
QM studies have empirically proved that a set of QM practices is positively linked to innovation (Feng et al., 2006; Hoang
et al., 2006; Perdomo-Ortiz et al., 2006; Abrunhosa et al., 2008;
Martinez-Costa and Martinez-Lorente; Prajogo and Hong, 2008).
The empirical studies emphasize that QM practices can provide
technicians or R&D workforces with opportunities for applying QM
principles and techniques in their innovative activities where the
opportunities enable them to efficiently detect customer demand,
to actively generate knowledge sharing, and to continue improvement of working systems and processes. Thus, the adoption of QM
in innovative activities helps an organization update changes in
customer needs, minimize non-value activities, and reduce new
product development time and costs. QM consequently generates
customer satisfaction, innovation, and improved business performance. Many other researchers, however, argue that not all QM
practices are directly related to performance or innovation (Flynn
et al., 1995; Ravichandran and Rai, 2000). In other words, because
a set of QM practices is interrelated there are relationships among
QM practices. The relationships among QM practices have either
a direct or indirect influence on performance. As Appendix B indicates, a QM practice, such as management leadership and training,
indirectly contributes to performance through other QM practices.
Therefore, in this section we discuss not only relationships among
QM practices, but also linkages between QM practices and innovation.
Management leadership refers to the extent to which top
management establishes quality goals and strategies, allocates
resources, participates in quality improvement efforts, and evaluates quality performance (Saraph et al., 1989). Most empirical
studies on QM provide a common view that management leadership is a starting point and significantly related to other QM
practices (Sila and Ebrahimpour, 2005; Zu et al., 2008; Kaynak,
2003; Flynn et al., 1995; Anderson et al., 1995; Ravichandran and
Rai, 2000; Ahire and Ravichandran, 2001). Management leadership is a minimum requirement to adopt and maintain other QM
practices. Researchers, including Ahir and Ravichandran (2001),
Ravichandran and Rai (2000), and Sila and Ebrahimpour (2005),
assert that the commitment of top management creates a sophisticated QM infrastructure that is needed for improving other QM
practices. Without strong top management support, it may be
impossible to build an effective environment for QM and produce benefits from other QM practices. According to the empirical
studies, management leadership is positively related to other QM
practices, especially training, employee relations, supplier quality management, customer relations, and product design (Flynn
et al., 1995; Kaynak, 2003). Top management establishes a learningintensive environment for the adoption of QM because they
ensure that adequate financial support is allocated for training
and monitoring performance through training. The development
of workforce skills and knowledge is required for understanding employee roles and achieving a better job. Top management,
a workforce motivator, also plays an important role in communicating with, motivating, and empowering employees. Top
management should trust employee performance, rather than
trying to control employees (Besterfield et al., 2003). Distributing responsibilities and accountabilities enables employees to
pay attention to organizational quality goals. Empirical studies
found a positive relationship between management leadership
and training, and employee relations (Anderson et al., 1995;
Rungtusanatham et al., 1998; Ravichandran and Rai, 2000; Ahire
and Ravichandran, 2001). This leads us to the following hypotheses:

H1. Management leadership will be positively associated with
training.
H2. Management leadership will be positively associated with
employee relations.
Top management establishes a long-term collaboration with
suppliers. The role of suppliers is very important in obtaining high
quality materials and leveraging unique knowledge and expertise
(Lemke et al., 2003). The information exchange about innovative
products and processes with suppliers enables a buying company
to reduce product development time and cost and to focus on critical work. Top management emphasizes that high quality is the
most important criterion in selecting a supplier. They understand
that organizational competitiveness can be increased if an organization relies on high quality materials, not cost-based judgment.
Further, improving customer satisfaction can be accomplished by
the commitment of top management. When top management
outlines quality goals for customer satisfaction, employees prioritize resources and their actions to contribute to this goal.
Using quality based principles, top management can motivate
employees to be involved in product design processes, develop
teamwork, and enhance productivity. Researchers have empirically
proven the positive relationship between management leadership
and supplier quality management (Flynn et al., 1995; Ahire and
Ravichandran, 2001; Kaynak, 2003), customer relations (Sila and
Ebrahimpour, 2005; Flynn et al., 1995; Ahire and Ravichandran,
2001), and product design (Flynn et al., 1995; Kaynak, 2003). From
this perspective, we suggest the following hypotheses:
H3. Management leadership will be positively associated with
supplier quality management.
H4. Management leadership will be positively associated with
customer relations.
H5. Management leadership will be positively associated with
product/service design.
Training refers to the extent to which an organization provides employees with statistical training, job-related skill training,
and quality-oriented training, such as quality techniques (Saraph

Both high and low risks.
et al., 1989). Empirical researchers, including Flynn et al. (1995),
Ravichandran and Rai (2000), and Kaynak (2003), hold a common
view that training is needed for developing employee participation
in organizational QM efforts and enhancing their knowledge and
skills on data collection and its use. Researchers have confirmed
that training is a basic factor in the success of QM implementation. Unless employees know how to implement concepts or
techniques of QM in their jobs, employees may resist and lack commitment to change, instead of giving a positive impetus or benefit.
A well-trained employee tends to work efficiently and effectively
to improve performance. Appropriate training offers opportunities for improving teamwork, reducing errors, and enhancing job
satisfaction. In particular, training is directly related to the way
employees work (Mehra et al., 2001). Employees recognize that
they should build strong teamwork. When an organization adopts
QM, employees should learn how to implement quality techniques
and quality principles in their innovation work. Therefore, the following hypotheses are proposed:
H6. Training will be positively associated with quality data and
reporting.
H7. Training will be positively associated with employee relations.
Employee relations refers to the extent to which employees
are involved in quality efforts, participate in quality decisions,
have responsibilities to provide quality, recognize superior quality performance, handle quality issues, and improve the general
awareness about quality (Saraph et al., 1989). According to empirical studies – including Flynn et al. (1995), Kaynak (2003), and
Ravichandran and Rai (2000) – employee involvement in quality efforts plays a key role in dealing with quality data, designing
products, and managing processes. The success of QM implementation can be ensured if responsibility for quality is extended to
all employees and all departments in an organization. Employees are the most important component in accomplishing success.
An employee should understand how his or her job fits into the
organizational goals and strategies to improve performance. Organizations should focus on encouraging employees to be involved
D. Y. Kim et al. / Journal of Operations Management 30 (2012) 295–315
in quality efforts and to be motivated and empowered. This is
because empowered employees demonstrate a strong sense of
ownership (Mehra et al., 2001). They understand the ways that
products/services are designed and improved, and they may discover other ways that products/services could increase customer
satisfaction (Summers, 2009). Employees struggle to learn quality
tools and techniques, such as check sheets, flow charts, and statistical process control. It is a common view that an empowered
employee effectively collects information, and measures and analyzes data (Zu et al., 2008). The employee clearly understands the
principle of continuing improvement. Further, an employee plays
a crucial role in identifying, maintaining, and enhancing processes.
An employee tries to implement quality improvement approaches,
such as plan-do-check-act (PDCA). Using a team problem-solving
approach and continuing improvement, employees can improve
product/service design (Choi and Eboch, 1998; Zu et al., 2008; Evans
and Lindsay, 2008). This leads us to the following hypotheses:
H8. Employee relations will be positively associated with quality
data and reporting.
H9. Employee relations will be positively associated with product/service design.
H10. Employee relations will be positively associated with process management.
Supplier quality management refers to the extent to which an
organization depends on fewer suppliers, is interdependent with
suppliers, emphasizes quality rather than price in purchasing policy, and supports suppliers in product development (Saraph et al.,
1989). The development of a solid partnership with suppliers
enables a buying company to exchange innovative ideas on new
products and improve development processes incrementally. In
other words, suppliers are seriously involved in the buyer’s product design teams by offering key information about prospective
components and detecting customer demand changes. This mutual
association helps the buying company not only reduce time and
cost in developing a new product, but also focus on its strategic technology development. Empirical studies have proven that
if a company has a strategic partnership with suppliers, the company may generate a positive performance enhancement in product
design and process management (Zu et al., 2008; Kaynak, 2003;
Flynn et al., 1995). Therefore, the following hypotheses are proposed:
H11. Supplier quality management will be positively associated
with product/service design.
H12. Supplier quality management will be positively associated
with process management.
Customer relations refer to the extent to which an organization emphasizes understanding customer needs (Ahire and
Ravichandran, 2001). A customer is one of the key decision makers in determining product specifications. A firm can understand
and respond to changing demands by analyzing quality data and
building a solid cooperation with customers. In other words, a close
association with customers requires a firm to promptly update
accurate information about customer demands, allowing the firm
to reduce redesign cost and time, to deliver high quality products,
and to satisfy customers. Existing empirical studies have proven
that a close relationship with customers positively contributes to
quality data (Mohrman et al., 1995; Forza and Flippini, 1998; Zu
et al., 2008). This leads us to the following hypothesis:
H13. Customer relations will be positively associated with quality
data and reporting.
Quality data and reporting refers to the extent to which an organization uses quality data, regularly measures quality, and evaluates
299
employees based on quality performance (Saraph et al., 1989).
Studies have empirically proved that managing quality data offers
opportunities for establishing a strategic relationship with suppliers, designing a new product, and improving processes, all of which
influence organizational performance (Kaynak, 2003). Organizations commonly use quality data when maintaining a partnership
with suppliers (Samson and Terziovski, 1999). Employees, as process owners in their jobs, can use quality data when selecting a
supplier, developing a specification, and assessing supplier performance. Further, in the product and service design stage, it is
essential for organizations to implement quality data to develop
customer-based products and prevent redesign. Design processes
tend to require much information and a wide range of data (Flynn
et al., 1995). It is possible for employees to appropriately analyze
and use quality data collected from other departments, such as marketing and R&D (Zu et al., 2008). Another benefit of quality data is to
help employees when modifying and improving processes (Kaynak,
2003). Employees constantly update and share quality data with
their colleagues. The management of quality data offers opportunities for identifying non-value-added processes and standardizing
product development processes, allowing employees to focus on
operating core processes. By relying on core processes, a firm is able
to reduce development time and cost and to be more responsive to
a competitive market. This leads us to the following hypotheses:
H14. Quality data and reporting will be positively associated with
supplier quality management.
H15. Quality data and reporting will be positively associated with
product and service design.
H16. Quality data and reporting will be positively associated with
process management.
Empirical studies have showed that quality data can play a vital
role in achieving innovation. Martinez-Costa and Martinez-Lorente
(2008), in an empirical study of 451 firms, found that the use of QM
tools leads to both product and process innovation. This infers that
by implementing QM tools, a firm can identify potential innovation
areas, develop innovation plans, and produce innovative products
and processes. Miller (1995), in a survey of 45 large multinational
firms, concluded that managing quality data is the most important
QM practice that can be applicable to innovative activities. Along
the same line, Mathur-De Vré (2000) found that QM practices help
to develop confidence in the credibility and reliability of all the
scientific data. Therefore, the following hypotheses are proposed:
H17-1. Quality data and reporting will be positively associated
with radical product innovation.
H17-2. Quality data and reporting will be positively associated
with incremental product innovation.
H17-3. Quality data and reporting will be positively associated
with radical process innovation.
H17-4. Quality data and reporting will be positively associated
with incremental process innovation.
H17-5. Quality data and reporting will be positively associated
with administrative innovation.
Product/service design is defined as the extent to which all
departments in an organization are involved in design reviews,
the extent to which an organization emphasizes productivity, the
extent to which an organization makes specifications clear, and the
extent to which an organization highlights quality (Saraph et al.,
1989). Product/service design aims at increasing design quality
and guaranteeing manufacturability design (Nair, 2006). Design
quality leads to standardizing components, simplifying designs,
and incorporating customer needs in design processes (Zu et al.,
300
D. Y. Kim et al. / Journal of Operations Management 30 (2012) 295–315
2008). Organizations should encourage constant communication
among customers, design engineers, and manufacturers (Flynn
et al., 1995). These efforts translate what employees understand
into specifications to appropriately design a product/service. An
efficient design is characterized by fewer and standardized components. These features result in efficient process management
because employees can reduce process variance and process complexity (Kaynak, 2003; Ahire and Dreyfus, 2000; Flynn et al., 1995).
Product/service design allows employees to reduce unnecessary
changes, to prevent problems with quality, and to minimize failure
rates (Zu et al., 2008). Empirical studies also indicate that product/service design can facilitate process management (e.g., Ahire
and Dreyfus, 2000; Kaynak, 2003). This leads us to the following
hypothesis:
H18. Product/service design will be positively associated with
process management.
Process management may positively relate to incremental, radical, and administrative innovation. Process management is based
on the notion that a firm’s capability is embedded in processes and
can be strengthened through effective management of processes
(Das and Joshi, 2011). Managing processes encourage firms to
develop best practices, called routines, that can be used to establish
a learning base and support innovative activities (Perdomo-Ortiz
et al., 2006). Process management involves two key activities:
repeating routines and enhancing routines. The repetition of routines refers to organizational efforts to document processes, to
measure process outcomes, and to repeat value-added processes
(ISO, 2008; Klassen and Menor, 2007). As the firms repeat the
critical processes, they have an opportunity to identify the best
practices that could be applied to any type of innovation activities. A set of best practices, or routines, is a source of incremental
learning (Benner and Tushman, 2002). Employees obtain knowledge and information through routines, while they measure and
monitor outcomes of routines in a systematic manner. Routines
are often applied to analyze root causes of a problem and prevent
any possible error or defect (Ahire and Dreyfus, 2000). By repeating routines, firms can develop the stable, detailed, and analytical
routines required to accomplish incremental process and product
innovation in moderately dynamic markets (Eisenhardt and Martin,
2000).
Routine-based firms efficiently carry out innovation activities
because they pay more attention to vital processes and avoid activities that do not add value (Hoang et al., 2006). Routines allow
firms to find and adopt efficient processes and methods. These
firms become more efficient in developing a new product from
idea generation to commercial success, making them more attractive to investors. Efficient processes also allow some slack time that
can be used to generate unique ideas and creative problem solving.
Additionally, implementing routines reduces variation in quality
and increases reliability in the outcome of a new product development project (Ravichandran and Rai, 2000). By using routines,
firms can set up a shorter and more efficient development cycle,
enabling them to innovate quickly and respond rapidly to customers (Nair, 2006). Routine-based firms can consistently produce
faster and better products or services than competitors. Further,
routines are of importance to firms struggling to innovate in their
own organizational structures and processes (Perdomo-Ortiz et al.,
2006). Routines include diverse procedures and skills that assist
employees in improving their administrative systems or functions.
Several empirical studies have shown that organizational routines
lead to incremental learning and innovation (Hoang et al., 2006;
Perdomo-Ortiz et al., 2006; Prajogo and Hong, 2008). Thus, we test
the premise that firms have to repeat and improve routines to trigger administrative, incremental product, and incremental process
innovation.
Enhancing routines, the second major activity, refers to a firm’s
long-term effort to tailor and continue to improve simple and
flexible routines for radical innovation activities. Radical innovation may cause several outcomes, such as a high failure rate and
uncertainty, a long-term development period, and costly investment. Stable and detailed routines may be limited to facilitate
only incremental innovation activities. For radical innovation, routines should be simple, flexible, and highly experiential to allow for
any unexpected adaptations in a high-velocity market (Eisenhardt
and Martin, 2000). Obtaining simple and flexible routines is a prerequisite for reducing uncertainty and leveraging risk (Valle and
Vázquez-Bustelo, 2009). Using routines, employees try to find new
opportunities and improve processes that lead to a previously
unrecognized demand. On the other hand, it is vital to guide radical innovation activities using formal routines, such as coordination
and evaluation routines. Formal routines provide a crucial framework for guiding a radical innovation project in terms of budget
and time. In various functions – such as R&D, marketing, and manufacturing – radical innovation projects often involve high risk and
progress concurrently or in parallel (Moguilnaia et al., 2005). As a
managerial guideline, routines play a significant role in completing
a radical project on time and on budget. To maintain clear project
goals and meet strict deadlines, managers use routines when evaluating and monitoring radical innovation projects. Using routines
that include measures and evaluation criteria in each development
stage, managers continue to assess project potential and sometimes terminate a poor project (Cooper, 1988). Written routines
are shared among participants across long-term projects, reducing communication gaps and unnecessary activities. It is logical to
assume that process management activities assist firms to establish a learning base and to continue to improve their innovation
capability. Therefore, we test the following hypotheses:
H19-1. Process management will be positively associated with
radical product innovation.
H19-2. Process management will be positively associated with
incremental product innovation.
H19-3. Process management will be positively associated with
radical process innovation.
H19-4. Process management will be positively associated with
incremental process innovation.
H19-5. Process management will be positively associated with
administrative innovation.
2.4. Research model
A proposed research model is shown in Fig. 1. Theoretical constructs and relationships among QM practices in the proposed
research model are identified from a structural model developed
by Kaynak (2003). Each relationship is double checked using the
prior empirical findings presented in Appendix B. The proposed
model is, however, different from the one of Kaynak (2003) in the
following two ways. This study develops its own hypotheses associated with a dependent variable based on the innovation literature.
Kaynak (2003) tested only the relationship between QM practices
and metrics used for traditional performances: quality, inventory,
and market performance. This study examines the link between
QM practices and five different types of innovation and adds a
hypothesis pertaining to a variable of QM practices: customer relations. Specifically, the proposed model examines a link between
customer relations and quality data and reporting. The model by
Kaynak (2003) did not encompass this link.
The model reflects a key philosophy of QM: the entire organization is a system of interlocking processes (Soltani et al., 2004).
D. Y. Kim et al. / Journal of Operations Management 30 (2012) 295–315
301
Fig. 1. Research model.
With respect to independent variables, this study utilizes a set of
QM practices developed by Saraph et al. (1989). The set of QM practices proposed by Saraph et al. (1989) is widely cited in QM studies
(Nair, 2006; Samson and Terziovski, 1999; Mehra et al., 2001; Sila
and Ebrahimpour, 2005) and often examined as one of the solid
sets in replication studies (e.g., Kaynak, 2003; Quazi et al., 1998;
Ho et al., 2001; Motwani et al., 1994; Kaynak and Hartley, 2005).
This study, however, customizes the set of QM practices developed
by Saraph et al. (1989). Unlike the original set of practices proposed by Saraph et al. (1989), the set of QM practices in this study
excludes one practice: the role of the quality department. The literature review shows that many organizations do not have a separate
quality department (Kaynak, 2003). Instead, a new practice (customer relations) is added in this study because customer-oriented
practice is broadly recognized as a representative QM practice in
the real world (Brah et al., 2000; Powell, 1995; Mehra et al., 2001;
Sila, 2007; Douglas and Judge, 2001; Zu et al., 2008; Samson and
Terziovski, 1999). Thus, eight QM practices, such as management
leadership and customer relations, are examined in this study. With
respect to dependent variables, this study examines five different
types of innovation: radical product, radical process, incremental
product, incremental process, and administrative. In earlier studies, the innovation construct is operationalized in terms of a single
item (product or process) or two items (product and process), not
these multiple types of innovation.
3. Methodology
3.1. Sample and data collection
A target sample of 2100 ISO 9001 certified manufacturing or service firms in Canada was selected. A stratified sampling technique
was used to obtain data from firms of different sizes: large, medium,
and small. The unit of analysis was the organizational level, as this
study seeks to find out whether QM practices lead to organizational
innovation. Earlier studies were conducted at the plant level (e.g.,
Flynn et al., 1995; Anderson et al., 1995; Rungtusanatham et al.,
1998; Ahire and Ravichandran, 2001; Zu et al., 2008). An organizational level study will add depth to the QM literature since there
is a relative lack of studies investigating the contribution of QM
practices at this level.
A questionnaire was mailed to 2100 firms. A total of 242
questionnaires were completed and returned. Of these, 19 were
incomplete and they were excluded because of a large number of
missing values in questions. One of the main reasons for this was
that the questions were not applicable for some firms. The analysis,
then, is based on a sample of 223 ISO 9001 certified manufacturing
or service firms, and the response rate is 10.6%. The respondents
were executives, middle-level managers, and professional staff. It
was assumed that they were sufficiently well informed of the extent
and role of QM practices in their firms to provide correct information. Similarly, previous studies reported that the commitment
and knowledge of the executives and managers is extremely crucial
when implementing QM (Burke, 1999). The sample consisted of 22
service firms (9.9%) and 201 manufacturing firms (90.1%). The manufacturing firms represented the following industries: 10 primary
metal manufacturing (4.5%); 15 machinery manufacturing (6.7%);
15 transportation equipment manufacturing (6.7%); 13 chemical
manufacturing (5.8%); 29 fabricated metal product manufacturing (13.0%); 18 computer and electronic product manufacturing
(8.1%); 11 electrical equipment, appliance, and component manufacturing (4.9%); and other industries, such as construction and
food packaging (40%).
To examine possible bias in self-report survey data, a nonresponse bias test and Harman’s one-factor test were conducted.
Non-response bias was assessed by performing a t-test on the
scores of early and late respondents. A basic assumption is
that the late respondents stand for opinions of non-respondents
(Armstrong and Overton, 1977). Respondents were divided into
two groups: 171 responses (76.7%) that were received in December
2009 and 52 responses (23.3%) that were received in January and
February 2010. The result of t-test between early and late respondents indicated no significant difference between the two groups.
Additionally, we conducted t-test using the scores of two groups
based on a demographic profile: firms with fewer than 50 employees (179; 80.3%) and firms with more than 50 employees (44;
19.7%). The t-test result on the different sized groups confirmed
that no significant difference was found in the groups. This means
that the data are free from non-response bias.
As this study relied on single respondents and perceptual scales
to measure dependent and independent variables, we assessed the
presence of common method variance (Scott and Bruce, 1994).
Common method variance refers to variance caused by measurement methods, threatening the validity of empirical findings and
misleading the interpretation of the results (Podsakoff et al., 2003).
We performed a confirmatory factor analysis (CFA) to Harman’s
one-factor test to check whether common method bias exists. One
factor, or a single factor, would account for most of the variance
when common method bias is a serious threat to the research
results (Podsakoff et al., 2003). It is assumed that common method
302
D. Y. Kim et al. / Journal of Operations Management 30 (2012) 295–315
variance is not a serious threat if the one-factor model has a poor
fit with the data (Das and Joshi, 2011; Kim, 2009; Bou-Llusar
et al., 2009). To develop the one-factor model, we loaded all of
the measurement items into a single factor. The CFA results indicated that the one-factor model did not fit the data (!2 = 5588.86
and df = 1274; !2 /df = 4.39; CFI = 0.83; RMSEA = 0.15; NFI = 0.79; and
NNFI = 0.82). Thus, we concluded that common method variance is
not a major concern in this study.
3.2. Measures
To design the measurement instrument, we used existing measurement items addressed in the literature. Most measurement
items for QM practices were adapted from the work of Saraph
et al. (1989) and Kaynak (2003). The variable of customer relations
was measured by using measurement items proposed by Flynn
et al. (1995) and Zu et al. (2008). Items for innovation were largely
adapted from the innovation literature, such as Herrmann et al.
(2007) and Valle and Vázquez-Bustelo (2009). In particular, this
study evaluates innovation with multiple measurement items. This
attempt is consistent with that of previous studies (e.g., Wan et al.,
2005), which argue that an empirical study on innovation should
not rely on only a single or a few innovation-related items, such
as R&D expenditures and patent counts. In this study, for example,
the construct of radical product innovation was operationalized by
five items. These items reflect the extent to which new products
differ substantially from other existing products, a firm introduces
radical product innovation into the market more frequently than
competitors, a percentage of radical product innovations in the
product range is significantly higher compared to the competition,
the percentage of total sales from radical product innovation is up
substantially, and a firm is known by customers for radical product innovations. A seven-point Likert type scale was used, where 1
is equal to strongly disagree and 7 is equal to strongly agree. The
questionnaire items included in each construct are presented in
Appendix C.
3.3. Measurement analysis
Structural equation modeling was used to test the measurement model and the proposed hypotheses. It is essential to test
hypotheses without any measurement influences related to reliability, unidimensionality, and validity (Shah and Goldstein, 2006). A
three-stage approach was employed to ensure that measurement
items were reliable, unidimensional, and valid. In the first stage,
reliability was assessed to identify the degree to which measures
are free from random measurement error (Kline, 2005). CFA, using
LISREL, was performed to explore reliability. Based on the results of
CFA, this study used two different methods: analyzing the squared
multiple correlation (R2 ) and examining the composite reliability
and the average variance extracted (Carr and Pearson, 1999; Boyer
and Hult, 2005b). First, reliability was examined by analyzing the
squared multiple correlation (R2 ) of individual items. The R2 -values
in a measurement model were computed as one minus the ratio of
the disturbance variance over the total variance (Kline, 2005, p.
252). Within the CFA setting, the R2 value of an individual item
should be greater than 0.30 (Carr and Pearson, 1999). It was found
that the R2 values of four items were below 0.30: SQM2 (0.14),
SQM3 (0.07), PRM2 (0.15), and ADMI4 (0.18). Thus, based on the
analysis results, four items were dropped at this stage. Further, the
composite reliability and the average variance extracted were calculated using completely standardized solutions in the CFA results
(Hult et al., 2004). According to a rule of thumb, a composite reliability of more than 0.7 or an average variance extracted of more
than 0.5 indicates acceptable reliability levels (Fornell and Larcker,
1981; Kim, 2009). The composite reliabilities ranged from 0.795 to
0.935, while the average variance extracted ranged from 0.564 to
0.742. The results reveal that all measures have a reasonable level
of reliability.
In the second stage, we tested for unidimensionality. Unidimensionality refers to the extent to which the measures in a scale
reflect one underlying construct (Venkatraman and Grant, 1986).
Following Sila and Ebrahimpour (2005), unidimensionality of QM
and innovation constructs was assessed using CFA. Prior to testing CFA, we checked factor loadings of each item by conducting
an exploratory factor analysis. The test aimed at removing items
that do not load on primary factors. According to the literature, a
factor loading of more than 0.40 or 0.45 is considered to be the minimum cutoff (Nunnally, 1978; Bhuian et al., 2005; Kathuria, 2000;
D’Souza and Williams, 2000; Terziovski et al., 1997; Samson and
Terziovski, 1999). The examination of factor loadings indicated that
factor loadings of all items ranged from 0.55 to 0.90. A total of 51
items were retained and used for CFA. Then CFA was run to assess
unidimensionality. The model fit was assessed by reviewing a set
of indices: Comparative Fit Index (CFI), Root Mean Square Error
of Approximation (RMSEA), the ratio of !2 to degree of freedom
(!2 /df), Normed Fit Index (NFI), and Non-Normed Fit Index (NNFI).
The literature suggests that the use of a set of indices is superior to
the application of a single index because each index has strengths
and weaknesses (Kline, 2005; Hu and Bentler, 1999). For example,
RMSEA is likely to over-reject models at a small sample size (Hu
and Bentler, 1999), while CFI is a relatively stable fit index (Gerbing
and Anderson, 1992). The indices have different rules to determine
excellent fit as follows: CFI, NFI, and NNFI > 0.9 (Bentler and Bonett,
1980; Byrne, 1998); RMSEA < 0.08 (Browne and Cudeck, 1993); and
!2 /df < 3.0 (Carmines and McIver, 1981; Bollen, 1989).
CFA was conducted to separately examine measurement models of each construct, such as management leadership, training,
and employee relations. The goodness of fit statistics showed a
good fit of all measurement models to the data. After testing the
measurement models of each construct, CFA was again performed
to assess two measurement models: one for QM practices and
the other for innovation. This attempt at assessing the two measurement models is consistent with an assessment methodology
suggested by Kaynak (2003). The results of CFA show an acceptable
fit for both measurement models. In the measurement model for
QM practices, the indices are as follows: CFI = 0.99; RMSEA = 0.039;
!2 /df = 630/456 = 1.38; NFI = 0.96; and NNFI = 0.99. Similarly, the
measurement model for innovation shows good fit statistics:
CFI = 0.97; RMSEA = 0.077; !2 /df = 316/147 = 2.15; NFI = 0.94; and
NNFI = 0.96. Thus, it is concluded that all constructs are unidimensional.
In the third stage, validity was assessed in terms of convergent
validity and discriminant validity. Convergent validity is identified
as the extent to which multiple attempts to measure the same
concept are in agreement (Bagozzi and Phillips, 1982). Convergent validity can be evaluated by examining the t-value from CFA
(Chen et al., 2004; Sila and Ebrahimpour, 2005). Each item’s coefficients on its underlying construct were observed (Anderson and
Gerbing, 1988). A measure should have convergent validity if the
value of its coefficient is greater than twice its standard error. In
other words, the t-values should be greater than two to achieve
strong convergent validity, where the t-values are calculated by
dividing the value of the coefficient by the standard error. The tvalues in this study ranged from 9.811 to 17.970. All measures have
strong evidence of convergent validity.
Discriminant validity refers to the extent to which a given construct is different from other constructs (John and Reve, 1982, p.
520). To test for discriminant validity, three approaches were used.
The first approach was to perform a chi-square difference test on all
pairs of constructs via CFA (Bagozzi and Phillips, 1982). For the test,
it was necessary to develop two models in each pair of constructs: a
D. Y. Kim et al. / Journal of Operations Management 30 (2012) 295–315
constrained model and an unconstrained model. In the constrained
model, a correlation parameter of a pair of constructs was constrained at 1. On the other hand, in the unconstrained model, a
correlation parameter was set to be free. A !2 difference value was
calculated by subtracting a !2 of the unconstrained model from a
!2 of the constrained model. To verify discriminant validity, the !2
difference value should be greater than 3.84 (Liang and Chen, 2009;
Kim, 2009). CFA was run twice on the models of constructs. The !2
difference values ranged from 4.135 to 41.859. This result indicates
that constructs exhibit strong discriminant validity.
Alternatively, the second approach for testing discriminant
validity was to compare the Cronbach’s ˛ of a construct and its
correlations with other constructs (Kaynak, 2003). According to a
rule of thumb, discriminant validity can be achieved if the Cronbach’s ˛ is greater than the correlations (Sila and Ebrahimpour,
2005). It was found that Cronbach’s ˛ values are greater than correlations. The third approach, proposed by Fornell and Larcker (1981),
is to compare the average variance extracted (AVE) and the squared
correlation between any two constructs. To establish discriminant
validity, a value of the AVE should be greater than a value of the
squared correlation (Fornell and Larcker, 1981; Batra and Sinha,
2000). The analysis result shows that values of AVE are considered
acceptable (see Appendix D). Thus, the analysis of measurement
models demonstrates that measures used in this study are reliable,
unidimensional, and valid.
3.4. Hypotheses testing
Fig. 2 shows the final structural model. Hypotheses were tested
using a latent variable model that included both latent variables
and observed variables. Unlike the path analysis that assumes no
measurement error, the latent variable model helps researchers
not only to identify prediction error and measurement error, but
also to accurately evaluate constructs and phenomena (Sila and
Ebrahimpour, 2005). LISREL, using the maximum likelihood estimation, was employed to estimate coefficient and t-statistics. A
t-value greater than 1.65 is significant at the 90% significance level,
a t-value greater than 1.96 is significant at the 95% significance level,
and a t-value greater than 2.58 is significant at the 99% significance
level (Kaynak, 2003).
Table 2 shows the analysis results of the structural model.
Overall results indicate 17 hypotheses were supported at the
95% or 99% significance level. The goodness of fit indices show
that the structural model fits the data: CFI = 0.98; RMSEA = 0.043;
!2 /df = 1714/1197 = 1.43; NFI = 0.94; and NNFI = 0.98. It should
be noted that all hypotheses related to management leadership (H1–H5) were supported: between management leadership
and training; between management leadership and employee
relations; between management leadership and supplier quality management; between management leadership and customer
relations; and between management leadership and product/service design. Moreover, significant paths were found in
relationships between other QM practices, such as between
training and employee relations. These statistical significances supported the following hypotheses: H6–H11, H13–H16, and H18. The
result also showed that process management is a significant and
direct predictor of five types of innovation, supporting H19. Process management is positively related to five types of innovation:
radical product, incremental product, radical process, incremental
process, and administrative. Further, it was found that the importance of process management varies with the type of innovation.
The contribution of process management is less in the case of
radical product innovation (coefficient: 0.41) when compared to
other types of innovation: incremental product innovation (0.86),
radical process innovation (0.79), incremental process innovation
(1.06), and administrative innovation (0.81). It was found that
303
non-significant relationships between quality data/reporting and
five types of innovation did not support H17. Supplier quality
management was not significantly related to process management
(ˇ = 0.09; t-value = 1.63) and did not support H12.
To further explore the relationship between QM practices and
innovation, indirect impacts were examined. Table 3 shows the
total and the indirect impacts of QM practices on innovation. One of
the important findings was that QM practices are significantly and
indirectly related to innovation. In particular, there were significant
and indirect links between all types of innovation and QM practices
(management leadership, training, employee relations, quality data
and reporting, and product/service design). Some QM practices
(supplier quality management and customer relations) were partially and indirectly related to a few types of innovation, such as
incremental or radical process innovation. Further, although there
was no significant and direct relationship between quality data and
reporting and innovation, quality data and reporting had a significant direct and indirect relationship with process management. It
can be interpreted that through process management, quality data
and reporting indirectly result in innovation. It is also noted that
quality data and reporting is indirectly associated with innovation,
although not directly related to innovation.
Additionally, we tested direct relationships between QM practices and innovation, which are not included in a set of hypotheses.
Thirty direct paths (e.g., management leadership → radical product
innovation; customer relations → incremental process innovation)
were added to the proposed structural model. The goodness of
fit indices showed that the model has a good fit to the data:
CFI = 0.98; RMSEA = 0.042; !2 /df = 1660.64/1167 = 1.42; NFI = 0.94;
and NNFI = 0.98. Four significant paths were additionally found
to be statistically significant paths. These paths were as follows:
between product/service design and radical product innovation (ˇ = 0.41; t-value = 2.29), between management leadership
and radical process innovation (ˇ = 0.25; t-value = 2.03), between
employee relations and incremental process innovation (ˇ = 0.50;
t-value = 2.71), and between management leadership and administrative innovation (ˇ = 0.28; t-value = 2.57). Perhaps these results
may be promising for further empirical research on the direct role
of QM practices on innovation.
4. Discussion and implications
The findings of this study support the notion that organizational
efforts to establish and improve QM practices relate positively to
innovative products or processes in both an existing market and an
emerging market. To be more specific, the analysis result indicates
that 17 out of 19 hypotheses are supported. Overall, the hypotheses
that are supported clearly show that QM practices through process
management are directly or indirectly associated with innovation.
The findings provide vital insights for academics and practitioners
interested in the relationship between QM practices and innovation.
Organizational capability to manage processes is very beneficial
to firms that are struggling to create radical and incremental innovations in a competitive market. This study confirms that process
management activities positively and directly relate to incremental, radical, and administrative innovation. Thus, it appears that
information and knowledge in a set of routines accumulated
through process management help firms establish a learning base
and facilitate innovative and creative activities. Stable and detailed
routines may add to the value of a product or a service in an
existing market, whereas simple and flexible routines are likely to
be valuable to firms targeting an emerging market. It also seems
that appropriate control for measuring performance and coordinating conflicts in critical processes is necessary for guiding and
304

generating incremental and radical innovation. Control in process
management is likely to assist firms to maintain stable goals, to
reduce product development time, and to meet customer needs in
both existing and emerging markets. This finding is consistent with
the empirical evidence found by Khazanchi et al. (2007) showing
that appropriate control, an innovation-supportive factor, enables
employees to innovate within proper boundaries and concentrate
on innovation initiatives.
Researchers also have pointed out that managing the process aids in facilitating creative problem solving and achieving
innovation. Benner and Tushman (2002) stressed that process management activities increase incremental learning that enhances
process efficiency and reduces variance in performance. In a longitudinal study, they reported that managing processes supports
knowledge sharing and incremental innovation. Salomo et al.
(2007), in an empirical study of 132 new product development
projects, found that the proficiency of process management is a
critical predictor of innovative performance in a new product development project. Using data from 108 technology service firms, Das
and Joshi (2011) highlighted that firms should manage processes to
encourage new ideas, creativity, and experimentation. They found
that a firm’s capacity for process improvement results in improving
innovation capability and providing a competitive advantage.
One implication of these findings is that firms can benefit from
identifying and enhancing organizational processes. Process management aids firms in fostering creative thinking, establishing
a learning base, and triggering incremental and radical innovation. It means that process-oriented firms are likely to develop

organizational capability for innovation by applying various QM
principles or techniques to engage in new ideas and creativity.
Firms are unlikely to build competitive advantage in existing or
emerging markets unless they invest their resources in process
management activities. Process management involves important
activities, such as identifying critical activities and repeating a set
of routines. These activities provide firms with opportunities for
generating incremental learning, increasing efficiency in a product development cycle, and responding quickly to customer needs.
Similarly, managers involved in innovation projects should put
more emphasis on employee ability to improve core processes and
apply well-developed routines to innovation activities. Managers
also need to be aware that stable and detailed routines generate incremental and administrative innovation, whereas simple
and flexible routines enhance radical innovation (Eisenhardt and
Martin, 2000). Depending on the target market, managers should
use different routines and develop criteria to select or terminate
an innovation project. Some short-term and cost-based routines
regarding the project selection criteria may inhibit radical innovation activities (Benner and Tushman, 2002). Therefore, it is critical
to understand the features and potential risks of radical innovation
and develop long-term and value-based selection criteria.
Another important finding is that emphasizing just one or a
few QM practices may not result in creative problem solving and
innovative performance. Our data indicate that QM practices are
interrelated with one another and influence innovation directly or
indirectly. This means that the significance of an individual QM
practice is strongly tied to other QM practices. QM practices seem
to provide advantages to firms in terms of innovative performance
only if a firm devotes attention to a set of QM practices, not just a few
techniques or tools. For example, we found management leadership to indirectly and positively relate to innovation through other
QM practices, such as training, employee relations, supplier quality
management, customer relations, and product and service design.
Similarly, supplier quality management is indirectly linked to innovation through product and service design. Process management
not only positively and directly relates to radical and incremental
innovation, but also mediates the influences of other practices, such
as quality data and reporting, employee relations, supplier quality
management, and product and service design.
Researchers have reached similar conclusions concerning the
importance of adopting a set of QM practices. Kaynak (2003), in
a study of 214 manufacturing and service companies, argued that
the validation of the interdependence of QM practices should be
emphasized to correctly understand the benefits of QM practices on
performance. Ahire and Ravichandran (2001) conducted an empirical study of 407 plants in the automobile industry. From their study,
Ahire and Ravichandran stressed that successful firms implement
QM in an integrated fashion, not a cherry-picking manner. Using
data from 130 R&D divisions of manufacturing firms, Prajogo and
Hong (2008) found that QM practices are interrelated and facilitate innovative activities. Martinez-Costa and Martinez-Lorente
(2008), in a study of 451 manufacturing and non-manufacturing
firms, stressed that QM practices should be measured with a multidimensional scale instead of a one-dimensional scale, because the
value of QM is based on a set of QM practices.
Another implication of these findings is that firms or managers
should not put excessive emphasis on a single or a few QM practices and techniques. Our analysis highlights the interdependency
of QM practices and the importance of a systematic approach for
managing QM practices. Given that QM requires a holistic organizational effort, firms need to invest in the development of various QM
practices that generate a creative synergy among individual practices. For managers and employees, a balanced and long-term view
about QM efforts and performance is a critical skill that they have
to possess. Firms that disregard a holistic perspective of QM and do
not focus on synergies of QM practices may fail to yield innovative
and financially rewarding performances. Thus, the overall improvement in a set of QM practices is fundamental to link organizational
efforts to innovation and leverage investments in QM. These suggestions will be very useful guidance for a firm when investing its
resources and changing its strategies to create innovation.
5. Conclusion and limitations
This study examines the relationship between QM practices and
innovation. A proposed model comprises eight QM practices and
five types of innovation. To test the proposed model, data were
collected from a sample of ISO 9001 certified manufacturing or service firms. The analysis shows that QM practices are associated with
innovation directly or indirectly and that the importance of individual QM practices is tied to other practices. In particular, the results
indicate that process management directly and positively relates
to all types of innovation.
306
D. Y. Kim et al. / Journal of Operations Management 30 (2012) 295–315
Limitations of this study should be recognized, providing
researchers with future research opportunities. First, respondents
for this study are ISO 9001 certified firms. The firms fit the research
purpose because they are familiar with terminologies and concepts
of QM practices. However, other QM-intensive firms, which were
awarded quality improvement awards such as the MBNQA or the
EFQA, might have been left out of this study. It would be promising to replicate this research using data collected from firms that
have been awarded the MBNQA or the EFQA but are not ISO 9001
certified. Further, it may not be possible to generalize our findings
for firms that are not ISO 9001 certified. Because our data involves
only ISO 9001 firms, the findings of this study may not be applicable to non-certified firms that are likely to have less-developed
quality programs. Future studies could be conducted to examine
the relationship between QM practices and innovation in both ISO
9001 certified firms and firms that are not certified.
A second limitation is the use of cross-sectional data. Although
the research is focused on examining the association between QM
and innovation across various organizations, it would be valuable
to conduct a longitudinal study within organizations. This attempt
would verify the finding of this research and improve understanding of the relationship of QM to innovation. Third, while this study
collected data based on respondents’ perceptual judgment, considering their performance within a firm, there is little attempt to
compare performance with other competitors in a similar industry. There is also no quantitative measurement item to evaluate
innovation. Though this study adapts measurement items from the
literature, future researchers need to develop more objective and
comprehensive measurement items for extending this research.
Fourth, it would be worthwhile to consider case studies to answer
why and how QM practices lead to innovation. Using a straightforward survey analysis, we focused on investigating the relationship
between QM practices and innovation. Our study could not clearly
answer questions such as how and why QM practices result in innovation. Case studies may offer in-depth insight on how QM-driven
firms create innovation efficiently and why process management is
the most important among QM practices in supporting innovation
activities.
Despite these limitations, this study contributes to the development of the literature in the following ways. The study enhances
our understanding of which QM practices relate to each other
and then, directly or indirectly, result in innovation. Earlier studies were limited to simply identifying a list of QM practices that
directly influence innovation. Unlike the previous studies, this
study investigates direct and indirect linkages among QM practices and clearly shows the positive relationships between QM
practices and innovation. Furthermore, this study extends the
boundaries of current studies by testing the relationship between
QM practices and five different types of innovation, such as radical product and incremental process innovation. We also provide
empirical evidence of the significance of process management
that may assist firms or managers to identify routines, to establish a learning base, and to support innovation initiatives. It will
be beneficial for practitioners to develop innovation strategies
and to allocate resources effectively, as needed by the type of
innovation.

Positive and significant
relationship between QM practices
and innovation.
Not all QM practices enhance
innovation.
Only three variables (leadership
and people management, process
and strategic management, and
open organization) showed a
positive impact on innovation.
Education and training, while
showing a positive effect on the
number of new products and
services, had a negative
relationship with the level of
newness.
Positive and significant
relationship between QM practices
and business innovation capability.
Three QM practices (process
management, product design, and
human resource management) are
more important than other
variables → It means that the
mechanistic QM practices also are
highly significant in the building of
business innovation capability
(BIC).
Evidence of the importance of size
is very slight.
No significant effects from
belonging to a business group.
The implementation of
technological audits in firms
significantly explains the presence
of innovative practices.
No significant relationships
between QM practices and
technological innovation.
Negative relationship between
formalization and technological
innovation.
No direct and positive relationship
between QM practices and
technical innovation.
No direct and positive relationship
between innovativeness and
administrative innovation.
Positive and direct relationship
between innovativeness and
technical innovation → the
mediating role of innovativeness is
required to achieve technical
innovation.
Positive and direct relationship
between QM practices and
administrative innovations.
The effect of QM on innovation is
moderated by market turbulence.
