Scenario Please read this scenario prior to answering the question You are serving as the Lead Architect for the enterprise architecture team at a large multinational aerospace and defense company. The company has grown rapidly by acquisition and has inherited numerous different procurement processes and related IT systems. Several procurement processes have had problems related to the timing of purchases, which has led to excess inventory. The Vice President in charge of Supply Chain Management has made the decision to consolidate and reduce redundant procurement processes and systems. The company will move to a "Just-in-time" procurement system so as to keep inventory costs low. TOGAF 9 is used for internal Enterprise Architecture activities. This project is using an iterative approach for executing the Architecture Development Method (ADM). At present, there are no particularly useful architectural assets in the Architecture Repository that are related to this initiative. All assets will need to be acquired, customized, or created from scratch. The company prefers to implement commercial off the shelf package applications with little customization. The CIO, who is the project sponsor, has stated that she is not concerned about preserving the existing procurement processes or systems. The architecture development project has completed the Preliminary Phase and has started a number of iteration cycles to develop the Architecture. As a packaged application is being considered, the next iteration will include both the Business and Application Architectures. Key stakeholder concerns that should be addressed by these architectures include: 1. What groups of people should be involved in procurement-related business processes? 2. What are the overall lifetimes of the Request for Proposal and Purchase Order business objects? 3. What non-procurement applications will need to be integrated with any new procurement applications? Refer to the Scenario [Note: You may need to refer to Chapter 35 of the reference text in order to answer this question.] You have been asked to identify the most appropriate catalogs, matrices, and diagrams to support the next iteration of Architecture development. Based on TOGAF, which of the following is the best answer?
Answer options
A: In the next iteration of Architecture development, you would describe the Baseline Business Architecture with a Business Service/Function catalog, an Organization/Actor catalog, and a Data Entity/Business Function matrix. You would describe the Baseline Application Architecture with an Application/Function matrix.
B: In the next iteration of Architecture development, you would describe the Target Business Architecture with a Business ServiceFunction catalog, an Organization/Actor catalog, and Data Lifecycle diagrams. You would describe the Target Application Architecture with Application Communication diagrams and an Application Interaction matrix. Correct answer
C: In the next iteration of Architecture development, you would describe the Target Business Architecture with a Business ServiceFunction catalog, a Business Interaction matrix, and Product Lifecycle diagrams. You would describe the Target Application Architecture with Application Communication diagrams and an Application Interaction matrix.
D: In the next iteration of Architecture development, you would describe the Baseline Business Architecture with a Baseline Business Process catalog, and an Object lifecycle catalog. You would describe the Baseline Application Architecture with a Technology Portfolio catalog.
Correct Answer:
B. In the next iteration of Architecture development, you would describe the Target Business Architecture with a Business ServiceFunction catalog, an Organization/Actor catalog, and Data Lifecycle diagrams. You would describe the Target Application Architecture with Application Communication diagrams and an Application Interaction matrix.
Explanation

The scenario indicates a forward-looking project to replace existing systems with a new COTS solution, and the CIO is not concerned with preserving the current state. This justifies focusing on the Target Architecture rather than the Baseline. The chosen artifacts in option B directly address the specific stakeholder concerns for the Business and Application Architecture phases.
1. Concern 1 (People): An Organization/Actor catalog is the correct artifact to identify the groups of people involved in business processes.
2. Concern 2 (Object Lifetimes): Data Lifecycle diagrams are designed to show the management of data entities (like a Purchase Order) from creation to destruction.
3. Concern 3 (Integration): Application Communication diagrams and the Application Interaction matrix are the primary artifacts for showing how different applications will be integrated and exchange information.

Why Incorrect

A. This option incorrectly focuses on the Baseline Architecture. The project sponsor has explicitly stated that preserving the existing systems is not a concern, making a detailed baseline analysis unnecessary.
C. This option incorrectly suggests a Product Lifecycle diagram. This artifact is used for the lifecycle of a company's products, not for the lifecycle of business data objects like a "Request for Proposal".
D. This option incorrectly focuses on the Baseline Architecture. It also includes a Technology Portfolio catalog, which is an artifact created during the Technology Architecture (Phase D), not the Application Architecture phase.

Organization/Actor Catalog: "The Organization/Actor catalog provides a list of the actors and roles that are involved in the architecture... It can be used to understand the actors and roles involved in business processes..." This directly supports addressing stakeholder concern #1.

Section 34.2.11

Data Lifecycle Diagram: "A Data Lifecycle diagram is used to show how the data in the enterprise is managed through its life cycle from creation to destruction." This directly supports addressing stakeholder concern #2 regarding the lifetimes of business objects.

Version 9.2

Part IV

Section 34.2.4

Application Communication Diagram: "An Application Communication diagram shows the key application components and the communication flows between them." This

along with the Application Interaction Matrix

directly supports addressing stakeholder concern #3 about integration.

Section 34.2.6

Application Interaction Matrix: "The Application Interaction matrix shows the communication and interaction patterns between applications in the enterprise." This also directly supports addressing stakeholder concern #3.

Phase B: Business Architecture - Approach: The standard notes that the extent to which the baseline is modeled depends on its intended use. Given the CIO's statement

a focus on the Target Architecture is the most appropriate approach.
