• Question 2 Smith Engines worldwide operations are organized by country. In Mexico, they have a field services division that only works with clients in Mexico and only interacts with the Smith Engines Mexican operations. In a project to redesign the field services process, the project team should define the system boundaries as Selected Answer: • All the functions, data, and organizational units of Smith Engines Mexican operations Question 3 A reason why it is important to understand the enterprise’s environment is: Selected Answer: • Enterprise systems are open, so they exchange material, information, and other resources with the environment Question 4 Which of the following statements is true Selected Answer: The appropriate level of abstraction depends on the model's purpose • Question 5 4 out of 4 points What are system dynamics? Selected Answer: • Systems Dynamics is a continuous simulation in which the system state changes continuously as a function of time Question 6 A project team is faced with the problem of how to improve on-time performance for an airline. To solve the problem, they decide to get employees from different parts of the company together in a conference room. What type of approach in thinking should be done and why? Selected This is a divergent type of thinking since it provides several multiple Answer: solutions to the problem as well as alternative plans. The main intention of divergent thinking is to graduate a problem into the next level, where the problem is taken to multiple solutions. This is a way of thinking that makes one-break problems into multiple pieces by looking at things that are necessary or unacceptable. It does this by thinking in an assumption way by relating everything with each other. It is because of this reason that the employees are brought together in a conference room. • Question 7 10 out of 10 points Suppose you work for a large retailer and are tasked with a project to design a new electronic system to place orders with the retailer’s vendors. How would you define where the boundaries are for the project? Selected The new system of the project should work from the beginning when is Answer: placing the order because boundaries usually set as the first key for any system action at the beginning when it hit the button. Also, the project system will end the boundaries action when the order is placed or submitted which means retails will send the request to vendors then boundaries end after the clicked button and have no process over the vendor process after retails click the button to send the request to vendor. • Question 8 Why does an enterprise need an enterprise frame work and how would they determine to use TOGAF, Zachman, Reynolds’ Enterprise Framework, SMART or another reference framework? Selected Enterprises require frameworks to help them solve issues in business process Answer: especially in architecture, where it helps to come up with a model design to make the organization such as stakeholders come to an understanding of the business, make the company compliant with the laws understand each subsystem’s steps by coming up with an advance design for the business process as well as to ensure that each part has been placed correctly in its right position. This helps in solving design problems by providing more details and it also makes it easy to understand the complexity of the design to come up with a bigger picture of the architecture that will be used in the longer term at a cheaper cost.It will also help in making better decision for the organization in the long term. There are several ways to come up with the framework due to various businesses as well as projects. However, the best framework that should be chosen is that which will bring together the stakeholders in order to discuss how they intend to see the system function. This is a business step that will aid the enterprise to have a future’s vision as well as improve the goals of their system. • Question 9 What makes an IT system ready for use in an Enterprise? What things would you test to ensure this? Selected When readying an IT system for the first use, I will first have to go through Answer: various processes. This includes planning, which will look at how the problem will be created up to where it is implemented. It will also involve taking the project through processes that include validation, security, verification, scalability, responsibility and reliability. It will later involve designing, creating, testing as well as implantation, this will later be followed with maintenance. In order to ensure that everything run smoothly, there should be a benchmark for each stage that has to be passed before moving to the next one. • Question 10 Elaborate on the relationship between business strategies/goals and IT initiatives.

This is because IT insures the needs of consumers and it also comes up with processes that are faster and better by using applications that are unique where it leads to high quality production at a reasonable cost. • Question 11 20 out of 20 points Why is modeling critical to EA? Why are UML diagrams used to display: business activity, business entity, & business use-case? Selected Model is critical to EA since it allows the visualization of the goals that Answer: needs to be in the path of modeling which can be perceived to be the viewpoint purpose as well as an abstraction level that displays in EA since modeling has been created with the main purpose of high abstraction level through the use of modeling method technique tools to include what it should understand in the abstraction as well as to enable the person who created the modeling mask what is not important. If looked at a different dimension, modeling can be perceived to be an art abstract that is used to pint to a high level of purpose.UML diagrams are use to display business activities, as well as use since they make understanding of finer details easier since they break down every business component when they are used. However, the more information at hand on consumer needs as well as preferences, the more understandable to the enterprise the more the process of production. • Question 12 What affect do many different stakeholders have on the enterprise design? Selected Having several stakeholders on enterprise design makes it hard to Answer: understand as well as the goals that have been set for it to achieve. In order to solve this problem there should be a methodology from the beginning during the designing process. This should be able to help stakeholders acquire knowledge and get to understand the real problem that the enterprise faces and deal with them accordingly. Moreover, if there is support from a more powerful stakeholder, there will be engagement to win more resources thus making the engagement have a higher chance of succeeding. With the stakeholders, experts will more likely anticipate the likely reaction to what they are doing thus they can build into the plans as well as actions that will be required to capitalize on the positive reaction while avoiding any negative reaction. • Question 13 Are most enterprise systems open or closed systems?

Selected Answer: Reference Architecture as a starting point • • It describes a structured set of models that collectively represent the building blocks of the system in a specific domain Knowledge Reuse – Reference Architectures embody the knowledge gathered, on a large scale, from a multitude of enterprise engineering projects How are Frameworks Anchored to Business Architecture • • • • • Frameworks should cover Enterprise needs “Align business architecture efforts with the framework content” Solve “alignment issues in your environment” Business needs should be “spelled out in your business architecture model Business architecture should relate to and shape that IT architecture
