Exam OGEA-102 Topic 1 Question 19 Discussion

Actual exam question for The Open Group's OGEA-102 exam
Question #: 19
Topic #: 1

Please read this scenario prior to answering the question
You are employed as an Enterprise Architect within a multinational company. The company has been very successful and has been buying companies around the world. This has led to a growing number of manufacturing divisions in various locations with a complex supply chain.
The top management recently expressed concerns about the company's effectiveness because of its multiple data centers and duplicate applications. The EA team has been working on a project to solve this issue. An analysis shows that supply chain issues have led to not enough products being produced to meet all the customer demand.
A strategic architecture has been defined to help meet customer demand and manage the supply chain more effectively. The strategic architecture involves combining different Enterprise Resource Planning (ERP) applications that are currently used separately in the company's production sites.
Each division has finished the Architecture Definition documentation to address their own specific manufacturing needs. The Enterprise Architects have agreed an overall strategy for the migration. They have defined a set of work packages that address the gaps found. They have defined the intermediate architectural states between the Baseline and Target architecture to add a new ERP environment into the company.
Because of the risks posed by this change from the current environment, the architects have recommended that a phased approach should be taken to implement the target architecture with several stages of change. They have created a draft roadmap with the implementation process estimated to take over two years.
The company has an established Enterprise Architecture (EA) practice and follows the TOGAF Architecture Development Method. The company also uses various management frameworks such as business planning, project/portfolio management, and operations management. The EA program is sponsored by the Chief Information Officer (CIO). In your role as an Enterprise Architect within the EA team, you work closely with the important stakeholders from the various divisions within the company.
Refer to the scenario
You have been assigned to plan the next steps for the migration. Which approach will you choose?
Based on the TOGAF standard which of the following is the best answer?

A. You finalize the Architecture Definition documentation with updates to reflect the implementation approach. You ensure that Implementation and Migration Plan is consistent with the chosen approach. You identify the resources needed to undertake the development projects. You would then produce an Implementation Governance Model to manage the lessons learned before finishing the plan. You ensure that the lessons learned are applied to the Implementation and Migration Plan. B. You estimate the business value for each project by applying the Business Value Assessment Technique to prioritize the migration projects and project steps. The assessment should focus on return on investment and criteria for evaluating performance to track the progress of the architecture transformation. You would confirm and plan a series of Transition Architecture phases using a table of Architecture Definition Increments that lists the projects. You then update the Implementation and Migration Plan. C. You will focus on project selection. You make sure that the Implementation and Migration plan aligns with the other management frameworks in use in the company. Next, you assign a value to each work package, taking into account the resources available and how they fit into the overall strategy. Using these work packages, you estimate resource requirements and timings. You then select which projects will be included in the Implementation and Migration Plan. D. You conduct a series of Compliance Assessments to check that the architecture is being implemented as required by the contract. This is done now to confirm that the implementation team is following the correct development process, and if not, so course correction is viable. This involves using monitoring tools and making sure that performance targets are being achieved. If the targets are not met, you would then need to make adjustments to the performance requirements and update them in the Implementation and

Migration Plan.
Explanation:
At this stage in the scenario:
A strategic architecture has been completed.
All divisions have completed their Architecture Definition Documents.
Work packages have been defined.
Transition Architectures between Baseline and Target are already identified.
A draft roadmap exists for a multi-year phased migration.
You are now asked to plan the next steps for the migration, which aligns exactly with TOGAF ADM Phase F: Implementation and Migration Planning.
In Phase F, TOGAF prescribes the following key activities:
Evaluate and prioritize projects and work packages
Determine business value, cost, risk, dependencies
Confirm Transition Architectures and sequencing
Update and finalize the Implementation & Migration Plan
Option B is the ONLY answer that correctly follows these required TOGAF steps.
✔ Why Option B is correct
Option B states:
"Estimate the business value for each project by applying the Business Value Assessment Technique ... to prioritize the migration projects."
✔ This is a TOGAF-recommended technique specifically for Phase F to evaluate and prioritize transformations using value, risk, and ROI.
"Confirm and plan a series of Transition Architecture phases ... using a table of Architecture Definition Increments."
✔ Exactly aligned with TOGAF:
Transition Architectures were identified earlier.
In Phase F, they must be confirmed, sequenced, and documented.
"Update the Implementation and Migration Plan."
✔ This is the required output of ADM Phase F.
✔ At this point, the plan must be validated and finalized based on value and prioritization.
Thus, Option B directly matches TOGAF's prescribed migration planning process.
✘ Why the other options are incorrect
A - Incorrect
Suggests finalizing Architecture Definition documentation-this was already completed by each division.
Introduces an "Implementation Governance Model," which is not a TOGAF artifact at this stage.
Focuses on lessons learned BEFORE execution, which is not appropriate for migration planning.
C - Incorrect
Focuses only on project selection and resource assignment.
Does not use TOGAF techniques for value/risk evaluation.
Does not reference Transition Architectures, which are central in the scenario.
Oversimplifies Implementation & Migration Planning to resource scheduling.
D - Incorrect
Compliance Assessments occur DURING execution, not before migration planning.
At this stage, no implementation has started, so compliance reviews are premature.
Adjusting performance requirements now has no alignment with TOGAF's ADM sequence.
