Exam OGEA-102 Topic 1 Question 8 Discussion

Actual exam question for The Open Group's OGEA-102 exam
Question #: 8
Topic #: 1

Please read this scenario prior to answering the question
You are employed as an Enterprise Architect working within the Enterprise Architecture (EA) team at an electric vehicle manufacturer. The company focuses on designing, manufacturing, and advancing battery technology for sustainable transportation, while also investing in charging infrastructure, autonomous driving systems, and renewable energy integration.
The company is introducing a major change to its vehicle design over a five-year period. This will be a cross-functional effort between hardware and software teams, delivering significant new features in the vehicles they manufacture. It is planned to be developed in phases. An architecture to support strategy has been completed with a roadmap for a set of projects.
The EA team has taken over the architecture for the hardware and software automotive platform used by current vehicles, some of which will be used again in the new vehicle design. The EA team has started to pick which parts of the architecture to use again.
The presentation and access to different variations of data that the company plans to offer through its vehicles creates a design challenge. The application portfolio and supporting infrastructure must connect with multiple cloud services and data repositories in different countries to be able to handle the data at a large scale.
Enough of the Business Architecture has been defined, so that work can commence on the Information Systems and Technology Architectures. Those architectures need to be defined to support the primary business services that the company plans to provide. These services will handle and use the data created by vehicles, preparing the way for self-driving vehicles in the future.
The company uses the TOGAF standard as the basis for its Enterprise Architecture framework. The EA team reports to the Chief Technical Officer (CTO), who is the sponsor of the EA program. The CTO requires that the EA team follow the purpose- based EA Capability model as described in the TOGAF Series Guide: A Practitioners' Approach to Developing Enterprise Architecture Following the TOGAF® ADM.
Refer to the scenario
How would you plan, organize, and manage the architecture development at this stage?
Based on the TOGAF standard which of the following is the best answer?

A. The superior architecture should be used to guide the approach. Review the identified projects, dependencies, and potential overlaps, then decide the order for starting the projects. Develop high-level architecture descriptions. For each project determine how much work is needed, identify reference architectures, and candidate building blocks. Identify the resource needs, considering cost and value. Document the different options, risks, and ways to control them to enable feasibility analysis and trade-off with the stakeholders. B. Start an iteration of ADM Phase A, perform a Stakeholder Analysis, identifying the key stakeholders and revising the Architecture Vision. Update the Stakeholder map created for the strategic architecture, so it reflects the stakeholders who are now the most important for the projects that are to be developed. Hold a formal review with the CTO, who should decide which projects to include in the Architecture Roadmap and update the Implementation and Migration Plan to reflect the decisions. C. Follow a standard pattern for cloud solutions that manage complex data, and which fits with the architecture to support strategy. Develop high-level Target Data, Application and Technology Architectures. Review the Architecture Vision to determine the level of detail, time, and scope of the ADM cycle phases required for architecture development for the project. Identify and estimate the cost of the main work packages. Create an Architecture Roadmap and request the Architecture Board to approve the roadmap. Start the project. D. Architecture descriptions for the Application, Data, and Technology Architectures should be developed at a suitable level to address the problems, and to identify the different options. For each project this includes identification of candidate architecture and solution building blocks. Solution providers should be identified, a readiness assessment performed, and an assessment of the viability and fitness of the solution options. The results should be added to the draft Implementation and Migration plan.

Suggested Answer: A Vote an answer

The scenario states that:
A strategic architecture and roadmap already exist.
Business Architecture is complete, so the work now shifts to Information Systems and Technology Architectures (ADM Phases B-D).
The CTO requires use of the purpose-based EA Capability model (from the TOGAF Series Guide: A Practitioner's Approach to Developing Enterprise Architecture Following the TOGAF ADM).
The EA team has to plan, organize, and manage the next stage of architecture development, including re-use of existing hardware/software platform components, candidate solutions, feasibility, risks, and prioritization.
Under the purpose-based EA approach, when moving from strategy into defining the next layers of architecture, TOGAF emphasizes:
Using the superior (already-approved) architecture to guide the next ADM cycles
- This corresponds to the strategic architecture that is already completed.
Analyzing project dependencies, overlaps, and sequencing
Defining high-level architecture descriptions for the next iteration
Identifying reference architectures and candidate building blocks (especially when reusing existing platform components) Assessing feasibility, value, cost, and risk for each project Preparing for stakeholder trade-offs before formalizing the roadmap These tasks map directly to Option A.
Why Option A is correct
Option A includes exactly what the purpose-based EA approach prescribes at this stage:
"The superior architecture should be used to guide the approach."
✔ Correct - strategic architecture guides the work.
"Review the identified projects, dependencies, and potential overlaps, then decide the order..."
✔ Correct - sequencing and dependency assessment are core early tasks in Phases B-D planning.
"Develop high-level architecture descriptions."
✔ Correct - Business Architecture is done; now high-level IS/Tech Architecture descriptions are needed.
"Identify reference architectures and candidate building blocks."
✔ Correct - aligns with TOGAF building-block approach, and specifically fits the scenario where existing platform components will be reused.
"Identify resource needs, considering cost and value."
✔ Correct - mandatory for feasibility and planning.
"Document options, risks, and ways to control them to enable feasibility analysis and trade-off with stakeholders."
✔ Correct - this matches ADM guidelines for preparing options and addressing complexity before deeper development.
This is precisely how TOGAF expects the architecture team to plan, organize, and manage an ADM cycle after strategy is set.
