質問 7：
Please read this scenario prior to answering the question
You are the Lead Enterprise Architect at a major agribusiness company. The company's main annual harvest is lentils, a highly valued food grown worldwide. The lentil parasite, broomrape, has been an increasing concern for many years and is now becoming resistant to chemical controls. In addition, changes in climate favor the propagation and growth of the parasite. As a result, the parasite cannot realistically be exterminated, and it has become pandemic, with lentil yields falling globally.
The CEO appreciates the seriousness of the situation and has set out a change in direction that is effectively a new business for the company. There are opportunities for new products, and new markets. The company will use the fields for another harvest and will cease to process third-party lentils. Thus, the target market will change, and the end-products will be different and more varied. This is a major decision and the CEO has stated a desire to repurpose rather than replace so as to manage the risks and limit the costs.
The company has a mature Enterprise Architecture practice based in its headquarters and uses the TOGAF standard as the method and guiding framework. The practice has an established Architecture Capability, and uses iteration for architecture development. The CIO is the sponsor of the activity.
The CIO has assigned the Enterprise Architecture team to this activity. At this stage there is no shared vision, or requirements.
Refer to the scenario
You have been asked to propose the best approach for architecture development to realize the CEO's change in direction for the company.
Based on the TOGAF standard which of the following is the best answer?
A. You propose that the team focus its iteration cycles on architecture development bygoing through the architecture definition phases (B-D) with a baseline first approach.This will support the change in direction as stated by the CEO. It will ensure that thechange can be defined in a structured manner and address the requirements needed torealize the change.
B. You propose that the team focus on architecture definition, with emphasis on definingthe change parameters to support this new business strategy that the CEO hasidentified. Once understood, the team will be in the best position to identify therequirements, drivers, issues, and constraints for the change.
You would ensure that thearchitecture development addresses non-functional requirements to assure that thetarget architecture is robust and secure.
C. You propose that the priority is to understand and bring structure to the definition of thechange. The team should focus iteration cycles on a baseline first approach toarchitecture development, and then transition planning. This will identify what needs tochange in order to transition from the baseline to the target, and can be used to work outin detail what the shared vision is for the change.
D. You propose that this engagement define the baseline Technology Architecture first inorder to assess the current infrastructure capacity and capability for the company. Thenthe focus should be on transition planning and incremental architecture deployment.This will identify requirements to ensure that the projects are sequenced in an optimalfashion so as to realize the change.

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 TOGAFADM.
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?
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 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.
C. 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.
D. 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.
