Scenario: You are working as an Enterprise Architect within an Enterprise Architecture (EA) team at an electric vehicle manufacturer. The company produces electric cars and battery systems. The goal of the company is to build the best technology and software platform for electric vehicles. The company has decided to introduce 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 inherited the architecture for the hardware and software automotive platform used by current vehicles, some of which can be carried over to the new vehicle design. The EA team has started to define which parts of the architecture to carry forward. The presentation and access to different variations of data that the company plans to offer through its vehicles creates an architecture challenge. The application portfolio and supportinginfrastructure must connect with multiple cloud services and data repositories in different countries to be able to handle large-scale data. Enough of the Business Architecture has been defined, so that work can commence on the Information Systems and Technology Architectures. These architectures need to be defined to support the primary business services that the company plans to provide. These services will manage and process the data created by vehicles, paving 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: You have been asked how to decide and organize the work to deliver the requested architectures. Based on the TOGAF standard, which of the following is the best answer?
Answer options
A: You commence an iteration of ADM Phase A, identifying the stakeholders and revising the Architecture Vision. You perform a Stakeholder Analysis and update the Stakeholder Map created for the strategic architecture so it reflects the stakeholders who are now the most important to the projects that are to be developed. You then request the CTO to make some choices about the Architecture Roadmap and update the Implementation and Migration Plan to reflect the choices.
B: You research leading data companies, using your findings to help in developing high-level Target Data, Application, and Technology Architectures. You 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. You identify and estimate the cost of the main work packages. You then create an Architecture Roadmap and request the Architecture Board to approve the roadmap. You then start the project.
C: You look to the superior architecture to help plan your approach. You identify projects, dependencies, and synergies, then decide the order for starting the projects. You then develop high- level architecture descriptions. For each project, you determine how much work is needed, identify reference architectures, and candidate building blocks. You identify the resource needs taking into account cost and value. You document the different options, risks, and ways to control them to enable feasibility analysis and trade-offs with the stakeholders. Correct answer
D: You look outside the company to study how other companies organize their data models and application portfolios. You request just enough architecture description for the Application, Data, and Technology Architectures to identify different options. For each project, this includesidentifying architecture and solution building blocks. You then identify solution providers and perform a readiness assessment on the new approaches.
Correct Answer:
C. You look to the superior architecture to help plan your approach. You identify projects, dependencies, and synergies, then decide the order for starting the projects. You then develop high- level architecture descriptions. For each project, you determine how much work is needed, identify reference architectures, and candidate building blocks. You identify the resource needs taking into account cost and value. You document the different options, risks, and ways to control them to enable feasibility analysis and trade-offs with the stakeholders.
Explanation

The scenario states that an "architecture to support strategy has been completed with a roadmap for a set of projects," meaning the EA team must now develop an Architecture to Support Portfolio. According to the TOGAF Series Guide: A Practitioners' Approach, this involves looking to the superior strategic architecture, identifying projects, dependencies, and synergies, and determining the sequence of projects. The architect must develop high-level architecture descriptions, identify reference architectures and building blocks, estimate resource needs, and document options and risks for feasibility analysis.

Why Incorrect

A: Commencing an iteration of ADM Phase A and updating the Implementation and Migration Plan skips the necessary portfolio-level planning and high-level architecture definition required before project initiation. B: Researching leading data companies and immediately creating Target Architectures ignores the need to align with the superior strategic architecture and organize the portfolio of projects first. D: Looking outside the company and identifying solution providers is premature; the portfolio must first be organized, and high-level architectures defined before selecting specific solutions.
