OG0-092 Exam - Question 15

Scenario:

You are serving as the Lead Architect for the enterprise architecture team at the prime contractor for the Dreadnought Unmanned Aircraft System program.

Over the course of this contract, the company has grown rapidly by acquisition and has inherited numerous different procurement processes and related IT systems. The decision has been made to consolidate and reduce redundant procurement processes and systems. The CEO has announced that the company will seek to leverage higher volume discounts and lower related IT support costs by instituting a preferred supplier program.

TOGAF 9 Is used for internal Enterprise Architecture activities, with an iterative approach for executing Architecture Development Method (ADM) projects.

At present, there are no particularly useful architectural assets related to this initiative, so all assets need to be acquired and 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 existing processes or systems.

The architect-re development project has put in place Its Architecture Capability for this project and has started a number of iteration cycles to develop the

Architecture. Some tasks to address concerns related to the Business Architecture have been completed. The next immediate task is to address the Information

Systems Architectures.

The Information Systems Architectures must address stakeholder concerns such as:

1. Which procurement-related business processes are supported by zero, one, or many existing applications?

2. What non-procurement applications will need to be integrated with any new procurement applications?

3. What data will need to be shared?

[Note: You may need to refer to TOGAF 9 Chapter 35 in order to answer this question.]

You have been asked to identify the most appropriate catalogs, matrices, and diagrams for this situation.

Based on TOGAF 9, which of the following is the best answer?

Show Answer
Correct Answer: C

Given the scenario and the stated preference for target architectures first, beginning with a Target Application Architecture using Application Communication diagrams and an Application Interaction matrix is appropriate. This approach aligns with the goal of integrating new procurement applications and understanding data sharing needs. A Data Entity/Business Function matrix and a System/Data matrix help define the Target Data Architecture. In later iterations, describing the Baseline Application Architecture with a System/Function matrix and the Baseline Data Architecture with a Data Entity/Data Component catalog provides a clear comparison for transition planning. This method uses appropriate TOGAF 9 tools to address stakeholder concerns and project requirements effectively.

C is correct for me, as the User/Application Location diagram does not make sense in the scenario

my approach. Firstly the decision based on - develop from the scratch - Target Architecture first. So you have eliminated A and D. Then you need to compare B and C. All diagram names are OK, but in B there is User/Application Location diagram. There was no question (who?) because of that Location and User are irrelevant. Also: C ist the right answer.

"The CIO, who is the project sponsor, has stated that she is not concerned about preserving existing processes or systems." Meaning TARGET first "Data Entity/Business Function matrix" makes C the correct answer

A is the answer for me. Point 1 and 2 require a system function matrix, and Point 3 would be completed in the data matrix. Also, baseline before target in most scenarios.

Answer B. I change my mind today. Point 1 and 2 require a system function matrix, and Point 3 would be completed in the data matrix. These points are still satisfied. As we are using COTS, I would go Target before Baseline as we have a high level overview of the target infrastructure. Target First: in this style, the target solution is elaborated in detail and then mapped back to the baseline, in order to identify change activity This process is suitable when a target state is agreed at a high level and where the enterprise wishes to effectively transition to the target model

Its going to be B or C. Target first which means one of them 2. I rule B out because it has user location diagram which is useless as per requirements. C is correct.

CIO is not concerned about retaining the existing platform, This is Target first as they have decided to use COTS Choice C is correct

I agree with the target first approach given the statement "The CIO, who is the project sponsor, has stated that she is not concerned about preserving existing processes or systems". I have a question though, why would you then go and create a baseline architecture? Does the new target architecture become the baseline?

Never mind my question, I got my answer: Target First: in this style, the target solution is elaborated in detail and then mapped back to the baseline, in order to identify change activity This process is suitable when a target state is agreed at a high level and where the enterprise wishes to effectively transition to the target model

no particularly useful architectual assets, so shall be baseline first. stakeholder's concern 2 need application communication diagram, which doesn't in answer D. So, A

So the approach should be to develop Target Architecture first.. so B & C. But B has given System/Data matrix which doesn't exist thus C is the Best Answer.
