Running Head: INFORMATION SYSTEMS
1. List and describe the four basic functions of an information system. List and
describe three types of enterprise systems.
An information system has four basic functions which include;
Input- This is all the data and information that is embedded in a system which will be used
for some reason (Gupta, 2011). Input is done through a variety of sources including keyboards,
scanners, and mouse or from another computer. Input does not have much importance until it
gets processed to provide output.
Processing- This is a function that takes place inside a computer system. In this case, the
input is covered by information that is more useful to the organization (Gupta, 2011). Most of
what is presented on the computer screens is the process of input being converted into
information that users will apply in their day to day operations.
Output- an information system has to provide the output which is data in processed form so
that it is referred to as information (Gupta, 2011). Output has many different forms including
monitors and printers. An information system may provide the output that is either short term,
for example, a printed photo or long term where information is stored in databases.
Storage- this is the function of storing processed information in the computer systems
(Gupta, 2011). This function is helpful since it can apply for future reference, and to avoid data
loss in the long term. Storage is vital for an organization and some of the mediums that can help
in storing data include hard disks, USB drives and CDs.
The three types of enterprise systems include
Enterprise resources planning systems- This integrates all the system applications in a
similar way like a company makes the integration of different functions such as finance,
inventory management, purchasing and human resource (Gupta, 2011).
Supply chain management- Helps organizations in coordinating the activities of people and
other resources as a way of increasing productivity within an organizational setting.
Customer relationship management- Software helps organizations in addressing the issue
of raising sales within the organization thus meeting the needs of the customers.

2. There are two fundamental requirements for managing business performance: being
able to measure and knowing that your indicator is measuring the right thing. Explain each
of these requirements and why they are challenging.
Managing the performance of a business requires an organization to;
Have the ability to measure- Most organizations fail in identifying the right methods to
apply in measuring performance. For instance, it remains unclear on the best method that an
organization should apply in effectively measuring performance. In some cases, some
organizations use profit as an indicator of improved or deteriorated performance while others use
customer satisfaction as the measure. On the other hand, there is no one measure that is
universally accepted as a way of measuring performance given that organizations operate in
different industries (Neely, 2001). As a result, an organization may not have the ability to
measure its success in performance as would be expected a reason why some fail. Also, some
organizations have not embraced measurement of performance since they find the activity as
both times consuming and expensive.
Know an organization's indicator- Every organization has an indicator which it uses in
measuring performance. In this case, key performance indicators are applicable n determining
whether an organization is moving towards the right direction or nor. However, for some firms,
knowing the indicator has remained a hard task and most of the organizations do not know the
best indicator to apply (Neely, 2001). Some of the performance indicators will include sales and
productivity. However, where an organization fails to identify the performance indicators that
suit its operations, it will remain hard to know the performance trend. For many companies,
failure to identify a performance indicator that best suits their daily operations remains a reason
as to why poor performance is experienced.
