Which of the following is a benefit of Value Stream Mapping?
- A. It helps to assess an organization's effectiveness at creating, capturing, and delivering value for different stakeholders.
- B. It helps to ensure that investments and project initiatives are prioritized and funded at a level matching with their value.
- C. It highlights the value of individual work packages needed to develop the business architecture.
- D. It helps to identify value, duplication, and redundancy across the enterprise.
正解：A
解説：
One of the benefits of Value Stream Mapping is that it helps to assess an organization's effectiveness at creating, capturing, and delivering value for different stakeholders2. Value Stream Mapping is a technique that can be used to represent a sequence of activities that create an overall result for a customer, stakeholder, or end user2. Value Stream Mapping can help to identify the value proposition, outcomes, measures, enablers, and dependencies of each activity in the value stream, as well as the overall value flow and performance2. By analyzing the value stream map, the organization can evaluate how well it is meeting the stakeholder needs and expectations, as well as identify opportunities for improvement or innovation.

- A. strategy
- B. best practices
- C. value
- D. business function
正解：C
解説：
A business model is a description of the rationale for how an organization creates, delivers, and captures value4. Value is defined as the worth or importance of something to someone6. A business model explains what value proposition the organization offers to its customers, what revenue streams it generates from delivering the value proposition, what cost structure it incurs to create and deliver the value proposition, what key resources and activities are needed to create and deliver the value proposition, and what key partnerships are leveraged to support the value creation and delivery process4.
質問 # 16
Which statement best describes iteration and the ADM?
- A. The level of detail is defined once and applies to all iterations.
- B. The ADM is iterative between phases B to D, and between Phases E and F.
- C. The ADM is sequential. Iteration is applied within phases.
- D. The ADM is iterative, over the whole process, between phases, and within phases.
正解：D
解説：
The statement that best describes iteration and the ADM is that the ADM is iterative, over the whole process, between phases, and within phases4. Iteration is a key concept in managing the complexity of developing an Enterprise Architecture and managing its lifecycle4. The ADM supports several forms of iteration as follows:
Iteration over the whole process: Projects will iterate through the entire ADM cycle, commencing with Phase A (Architecture Vision) and ending with Phase H (Architecture Change Management)4. Each cycle of the ADM will be bound by a Request for Architecture Work that defines the scope and objectives of the project4. The architecture output will populate or update the Architecture Landscape that describes the current and target states of the enterprise4.
Iteration between phases: Projects may cycle between ADM phases in planned cycles covering multiple phases4. Typically, this is used to converge on a detailed Target Architecture when higher-level architecture does not exist to provide context and constraint4. For example, a project may iterate between Phase B (Business Architecture), Phase C (Information Systems Architectures), and Phase D (Technology Architecture) until a satisfactory solution is achieved4.
Iteration within phases: Projects may return to previous activities within an ADM phase in order to circle back and update work products with new information4. Typically, this is used to manage the inter-relationship between different aspects of an architecture domain or viewpoint4. For example, a project may revisit Business Architecture models after developing Information Systems Architecture models to ensure alignment and consistency4.
質問 # 17
Which of the following best describes where business scenarios are used in the TOGAF ADM?
- A. They are used as part of a business transformation readiness assessment in Phase E.
- B. They are used to resolve impacts across the Architecture Landscape in Phases B, C, and D.
- C. They are used as part of the lessons learned activity at the end of Phase F.
- D. They are used in the Preliminary Phase, Phase A, and Phase B.
正解：D
解説：
According to the TOGAF Standard, business scenarios are an important technique that may be used at various stages of the enterprise architecture, principally the Architecture Vision and the Business Architecture, but in other architecture domains as well, if required, to derive the characteristics of the architecture directly from the high-level requirements of the business1. The Architecture Vision is developed in Phase A, and the Business Architecture is developed in Phase B. The Preliminary Phase is also a stage where business scenarios can be used to help identify and understand business needs2.

- A. Value networks
- B. Lean value streams
- C. Value streams
- D. Value chains
正解：A
解説：
Value networks are an approach to model, measure, and analyze business value that is primarily concerned with identifying the participants involved in creating and delivering value3. Value networks focus on the relationships and interactions among the participants, such as customers, suppliers, partners, employees, and other stakeholders3. Value networks can help to understand how value flows through the network and how it can be improved or optimized.
質問 # 20
Which of the following is a derived relationship in an organization map?
- A. Capability
- B. Location
- C. Scope of enterprise
- D. Value flow
正解：D
解説：
According to the TOGAF Series Guide: Organization Mapping, one of the derived relationships in an organization map is value flow1. A value flow is a relationship that shows how value is exchanged between business units or other entities in an organization map1. A value flow can be expressed as a verb phrase that indicates what type of value is transferred or shared between entities1. For example, in an organization map for an online retailer, a possible value flow could be "Delivers products" between the Warehouse business unit and the Customer entity.
質問 # 21
Consider the following modeling example, relating business capabilities to organization units so as to highlight duplication and redundancy:
(Note in this example the cells colored green, yellow, and red, are also marked G. Y, and R, respectively) Which of the following best describes this technique?
- A. Gap Analysis
- B. Capability Mapping
- C. Perspective Analysis
- D. Relationship Mapping
正解：D
解説：
The technique shown in the example is called relationship mapping. It is a technique that can be used to show how a business architecture addresses stakeholder concerns across different parts of an organization2. It can highlight gaps or overlaps in the coverage of stakeholder concerns by a business architecture. In this case, the technique is used to relate business capabilities to organization units so as to highlight duplication and redundancy.
質問 # 22
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. A new value stream was assessed as in the project scope.
- B. The development of Business Architecture Descriptions is always iterative.
- C. Phase B requires that all Architecture Descriptions be updated.
- D. Phase B is an ADM Architecture Development phase.
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.
