Question #: 7

Topic #: 1

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?

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

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 Boa

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 optio

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.

Explanation

The correct answer is C, as it aligns with the TOGAF ADM approach and best practices for organizing architecture work in a phased and structured manner.

Analysis of the Correct Answer (Option C):

Identifying Projects, Dependencies, and Synergies

The scenario describes a phased approach to vehicle development over five years.

Identifying dependencies ensures a logical and structured rollout of technology and business capabilities.

Developing High-Level Architecture Descriptions

Since Business Architecture is already defined, it is now time to develop high-level descriptions of Information Systems and Technology Architectures.

TOGAF emphasizes incremental and iterative refinement, meaning that starting with high-level descriptions is a logical first step.

Determining Workload and Resource Allocation

TOGAF ADM Phase B, C, and D involve creating architecture descriptions.

Understanding how much work is required ensures efficient resource planning and allocation.

Identifying Reference Architectures and Building Blocks

Using reference architectures and reusable architecture building blocks (ABBs) is a key best practice in TOGAF.

This enables efficiency and consistency in architecture development.

Evaluating Costs, Risks, and Feasibility

TOGAF emphasizes a risk-aware approach to enterprise architecture.

Documenting options, risks, and control measures ensures feasibility before execution.

Why Other Options Are Incorrect?

Option A: Initiating ADM Phase A Again

Incorrect because the scenario states that the Architecture Vision has already been completed.

Phase A is used for initial vision-setting, but at this point, the focus is on executing defined architectures.

Option B: Researching Data Companies for Target Architecture Development

Incorrect because the focus should be on defining internal architectures rather than external research.

While benchmarking best practices can be useful, it is not the primary activity at this stage.

Option D: Studying Other Companies and Performing Readiness Assessment

Incorrect because the focus should be on leveraging the organization's existing architecture and resources.

Solution provider readiness assessments are typically part of procurement, not enterprise architecture development.
