質問 # 27
Which of the following best describes the relationship between business models and business architecture?
- A. Business Architecture breaks a business model down into the core functional elements that describe how the business works.
- B. Business model development is a prerequisite for a Business Architecture development.
- C. Business Architecture provides a conceptual summary view, whereas business models support in-depth analysis.
- D. Business models are useful for impact analysis, however Business Architecture is needed for scenario analysis.
正解：A
解説：
A business model describes how an organization creates, delivers, and captures value for its stakeholders3. A business architecture breaks a business model down into the core functional elements that describe how the business works, such as the value proposition, the customer segments, the channels, the revenue streams, the cost structure, the key resources, the key activities, and the key partnerships3.
質問 # 28
Consider the following:
In Phase A a business capability map and a core set of value streams were created while developing the Architecture Vision.
Why would such Architecture Descriptions need to be updated in Phase B?
- A. Phase B is an ADM Architecture Development phase.
- B. The development of Business Architecture Descriptions is always iterative.
- C. A new value stream was assessed as in the project scope.
- D. Phase B requires that all Architecture Descriptions be updated.
正解：B
解説：
The development of Business Architecture Descriptions is always iterative because it involves constant refinement and validation of the architecture models and views based on stakeholder feedback and changing requirements. Therefore, any Architecture Description that was created in Phase A may need to be updated in Phase B as new information or insights emerge. Phase B does not require that all Architecture Descriptions be updated, only those that are relevant and necessary for the Business Architecture. Phase B is an ADM Architecture Development phase, but that does not explain why Architecture Descriptions need to be updated. A new value stream may or may not require updating existing Architecture Descriptions depending on its scope and impact.
質問 # 29
Which of the following is a difference between an organization map and an organization chart?
- A. An organization map reduces the time, cost, and risk of business operations.
- B. An organization map can be impacted by a business model change.
- C. An organization map is limited to formal relationships between business units.
- D. An organization map highlights where in the organization that stakeholder concerns are not being addressed by a business architecture.
正解：D
解説：
An organization map is a technique that can be used to show how a business architecture addresses stakeholder concerns across different parts of an organization3. It can highlight gaps or overlaps in the coverage of stakeholder concerns by a business architecture. An organization chart, on the other hand, is a diagram that shows the formal structure and hierarchy of an organization, such as reporting relationships and roles4. An organization chart does not necessarily show how stakeholder concerns are addressed by a business architecture.

Requirements Management (label 1): This phase provides a process for managing architecture requirements throughout the ADM cycle3. It ensures that requirements are captured, stored, prioritized, and addressed by relevant ADM phases3. It also ensures that requirements are validated and updated as necessary3.
Implementation Governance (label 2): This phase provides a process for ensuring that the implementation projects conform to the defined architecture3. It involves establishing an implementation governance model, defining architecture contracts and compliance reviews, and monitoring and supporting the implementation projects3.
Preliminary (label 3): This phase provides a process for preparing and planning the architecture project3. It involves defining the scope and vision of the project, customizing the ADM process and content framework, defining principles and governance structures, and evaluating the enterprise architecture maturity and readiness3.
