[All OGEA-103 Questions]

Please read this scenario prior to answering the question

You have been appointed as Chief Enterprise Architect (CEA), reporting to the Chief Technical Officer (CTO), of a company established as a separate operating entity by a major automotive manufacturer. The mission of the company is to build a new industry leading unified technology and software platform for electric vehicles.

The company uses the TOGAF Standard as the basis for its Enterprise Architecture (EA) framework, and architecture development follows the purpose-based EA Capability model as described in the TOGAF Series Guide: A Practitioners’ Approach to Developing Enterprise Architecture Following the TOGAF® ADM.

An end-to-end Target Architecture has been completed with a roadmap for change over a five-year period. The new platform will be a cross-functional effort between hardware and software teams, with significant changes over the old platform. It is expected to be developed in several stages over three years. The EA team has inherited the architecture for the previous generation hardware and software automotive platform, some of which can be carried over to the new unified platform. The EA team has started to define the new platform, including defining which parts of the architecture to carry forward.

Enough of the Business Architecture has been defined, so that work can commence on the Information Systems and Technology Architectures. Those need to be defined to support the core business services that the company plans to provide. The core services will feature an innovative approach with swarm data generated by vehicles, paving the way for autonomous driving in the future.

The presentation and access to different variations of data that the company plans to offer through its platform pose an architecture challenge. The application portfolio and supporting infrastructure need to interact with various existing cloud services and data-lakes in many countries to be able to manage the data at scale.


Refer to the scenario -

You have been asked what approach should be taken to determine and organize the work to deliver the requested architectures?

Based on the TOGAF standard which of the following is the best answer?

  • A. You will revisit ADM Phase A, identifying the stakeholders and creating a new Architecture Vision. You will update the Stakeholder map produced for the strategic architecture so it reflects the stakeholders who are now the most relevant to the projects that are to be developed. You would then ask the CTO to make some decisions about the Architecture Roadmap and update the Implementation and Migration Plan to reflect the decisions.
  • B. You would refer to the end-to-end Target Architecture for guidance and direction. The first objective should be to identify projects, dependencies and synergies, then prioritize before initiating the projects. You will develop high-level architecture descriptions. For each project you would estimate effort size, identify reference architectures, and candidate building blocks. You will identify the resource needs considering cost and value. You will document options, risks, and controls to enable viability analysis and trade-off with the stakeholders.
  • C. You will research leading data businesses developing high-level Target Data Application and Technology Architectures. You would review the Architecture Vision in order to estimate the level of detail, time, and breadth of the ADM cycle phases that will be needed to develop the architecture. You will identify and cost major work packages, and then develop an Architecture Roadmap. You would then seek approval by the Architecture Board and initiate the project.
  • D. You would look outside the enterprise to research data models and application portfolios of leading big data businesses. You would develop just enough applications, data, and technology architecture to identify options. For each project this should include identification of candidate architecture and solution building blocks. You will identify solution providers perform a readiness assessment, and assess the viability and fitness of the solution options. You will then document the draft Implementation and Migration plan.

Option B TOGAF ADM Alignment: This approach aligns with the Architecture Development Method (ADM) steps for progressing from an established target architecture to detailed project planning, ensuring dependencies and synergies are considered for prioritization. • High-Level Planning: Developing high-level architecture descriptions and identifying building blocks supports initial project planning and estimation, which fits into the next phase after the end-to-end Target Architecture has been defined. • Resource and Viability Considerations: Assessing effort size, resources, costs, and value ensures practical project management and alignment with stakeholder needs, an essential step in moving forward with an implementation strategy. • Risk Management: Documenting risks, controls, and enabling stakeholder trade-offs supports informed decision-making and aligns with TOGAF’s emphasis on stakeholder engagement and managing change effectively.
