• Question 11:

  Which of the following is a difference between an organization map and an organization chart?

  A. An organization map highlights where in the organization that stakeholder concerns are not being addressed by a business architecture.

  B. An organization map can be impacted by a business model change.

  C. An organization map reduces the time, cost, and risk of business operations.

  D. An organization map is limited to formal relationships between business units.

  Correct Answer: A

  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.

  An organization map differs from an organization chart in that it is designed to show more than just the formal hierarchy and relationships between different units within an organization. It provides a view of the enterprise from the perspective of the business architecture, highlighting areas where stakeholder concerns might not be addressed effectively, whereas an organization chart typically shows the formal reporting structures only.

• Question 12:

  Consider the following graphic illustrating a method supporting the TOGAF ADM.

  

  What does the method help identify?

  A. Solution Building Blocks

  B. Business Scenarios

  C. Alternative Target Architectures

  D. Architecture Solutions

  Correct Answer: C

  The graphic illustrates a method for developing alternative target architectures in Phase E of the TOGAF ADM1. The method involves identifying and evaluating candidate architectures based on criteria such as business value, cost, risk, and feasibility1. The method helps to identify the most suitable architecture solution for the enterprise.

  The graphic illustrates a method that supports the TOGAF ADM by identifying and evaluating alternative target architectures. The process begins with a vision, influenced by principles and requirements, leading to the consideration of alternatives. Each alternative is assessed based on different criteria, leading to the selection of the most suitable target architecture. This is consistent with the TOGAF approach of developing a set of potential architectures and then selecting the one that best meets the enterprise's needs.

• Question 13:

  When developing a Business Architecture, which of the following best describes the approach to take If no Architecture Descriptions exist?

  A. Review the contents of the Architecture Repository.

  B. Identify the business goals, business objectives, and drivers for the enterprise

  C. Information should be gathered, and Business Architecture models developed.

  D. Validate the business principles and update the Statement of Architecture Work.

  Correct Answer: C

  In the absence of existing Architecture Descriptions, the development of a Business Architecture would begin with the gathering of relevant information about the business. This information can come from strategic documents, business plans, process documents, and stakeholder interviews, among other sources. Once gathered, this information would be used to create Business Architecture models that articulate the business vision, strategy, governance, organization, and key business processes. These models provide a blueprint that captures the essence of the business and guides subsequent architecture work.

• Question 14:

  Which of the following is guidance for creating value streams?

  A. Identify the top-level value streams from components of capabilities.

  B. Include operational levels of detail.

  C. Start with customer-based value streams.

  D. Create an initial set of value streams that map one-to-one to existing capabilities.

  Correct Answer: C

  When creating value streams, it is recommended to start with customer-based value streams. Here's a detailed explanation:

  Value Streams:

  Definition: Value streams represent the end-to-end activities that create value for customers or stakeholders. They provide a high-level view of how value is delivered within the organization.

  Starting with Customer-Based Value Streams:

  Customer Focus: Starting with customer-based value streams ensures that the architecture is aligned with the needs and expectations of the customers. This approach helps in identifying the most critical value-creating activities and aligning

  them with business goals.

  Value Delivery: Customer-based value streams provide a clear understanding of how value is delivered from the customer's perspective. This helps in designing processes and capabilities that enhance customer satisfaction and business

  performance.

  TOGAF References:

  Phase B: Business Architecture: In this phase, value streams are identified and modeled to ensure that the architecture supports the delivery of value to customers. Starting with customer-based value streams is a key activity in this phase.

  Capability-Based Planning: TOGAF emphasizes the importance of aligning business capabilities with value streams to ensure that the architecture supports value creation and delivery.

  Benefits:

  Customer-Centric Design: Starting with customer-based value streams ensures that the architecture is designed with a focus on customer needs and value delivery. Strategic Alignment: Aligning value streams with customer needs helps in

  ensuring that the architecture supports the strategic goals of the organization and enhances customer satisfaction.

  In summary, when creating value streams, starting with customer-based value streams ensures a customer-centric design, aligning the architecture with the needs and expectations of the customers and supporting strategic goals.

• Question 15:

  Which of the following is the element of a value stream stage that describes the state change that triggers the value stream stage?

  A. Baseline state

  B. Enhance criteria

  C. Starting point

  D. Gating stage

  Correct Answer: D

  In the context of value stream stages, a gating stage is the element that describes the specific state change which triggers the next stage of the value stream to begin. It acts as a checkpoint that ensures that certain criteria are met before the process can proceed to the next phase.

• Question 16:

  Which of the following best describes the relationship between business models and business architecture?

  A. Business model development is a prerequisite for a Business Architecture development.

  B. Business Architecture articulates the different perspectives and impacts of the business model.

  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.

  Correct Answer: B

  The relationship between business models and business architecture in TOGAF can be described as follows:

  Business Models:

  Definition: Business models describe how an organization creates, delivers, and captures value. They provide a high-level overview of the business, including elements such as value propositions, customer segments, channels, and revenue

  streams.

  Purpose: Business models are used to understand and analyze the core elements of the business and how they interact to create value.

  Business Architecture:

  Definition: Business architecture provides a detailed view of the business, including its structure, capabilities, processes, and information. It articulates how the business operates and supports the business model. Purpose: Business

  architecture translates the high-level view of the business model into detailed architectural views and artifacts. It ensures that the architecture aligns with the business strategy and supports the execution of the business model.

  Relationship:

  Articulation of Perspectives: Business architecture articulates the different perspectives and impacts of the business model by providing detailed views of the business components that support the model. This includes defining the necessary

  capabilities, processes, and organizational structures.

  Alignment and Execution: Business architecture ensures that the architecture aligns with the business model and supports its execution. It translates the strategic intent of the business model into actionable and implementable architectural

  components.

  TOGAF References:

  Phase B: Business Architecture: This phase involves developing a detailed business architecture that aligns with and supports the business model. It includes identifying and defining business capabilities, processes, and organizational

  structures.

  Strategic Planning: TOGAF emphasizes the importance of aligning business architecture with business strategy and models to ensure that the architecture supports the overall business goals.

  Benefits:

  Comprehensive Understanding: By articulating the different perspectives and impacts of the business model, business architecture provides a comprehensive understanding of how the business operates and delivers value. Strategic

  Alignment: Ensures that the architecture is aligned with the business strategy and supports the execution of the business model, leading to better business outcomes.

  In summary, business architecture articulates the different perspectives and impacts of the business model by providing detailed views of the business components that support the model, ensuring alignment and effective execution of the

  business strategy.

• Question 17:

  Which approach to model, measure, and analyze business value is primarily concerned with identifying the participants involved in creating and delivering value?

  A. Value chains

  B. Value networks

  C. Lean value streams

  D. Value streams

  Correct Answer: B

  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.

• Question 18:

  Which of the following supports the need to govern Enterprise Architecture?

  A. The Architecture Project mandates the governance of the target architecture.

  B. The TOGAF standard cannot be used without executive governance.

  C. Best practice governance enables the organization to control value realization.

  D. The stakeholder preferences may go beyond the architecture project scope and needs control.

  Correct Answer: C

  One of the reasons that supports the need to govern Enterprise Architecture is that best practice governance enables the organization to control value realization6. Value realization is the process of ensuring that the expected benefits from implementing an Enterprise Architecture are achieved and sustained over time6. Best practice governance provides a framework and mechanisms for monitoring and evaluating the performance and outcomes of Enterprise Architecture initiatives, as well as ensuring alignment with strategic objectives and stakeholder expectations.

• Question 19:

  Complete the sentence. A key principle of value streams is that value is always defined from the perspective of the_____________

  A. Shareholder

  B. Architect

  C. Sponsor

  D. Stakeholder

  Correct Answer: D

  A key principle of value streams is that value is always defined from the perspective of the stakeholder2. A stakeholder is any person or group who has an interest in or influence on an enterprise or its activities5. A stakeholder can be internal or external to the enterprise. A stakeholder can also be a customer, end user, partner, supplier, regulator, employee, or any other role that interacts with or benefits from the enterprise's products or services5. Value streams should reflect how stakeholders perceive and measure value in terms of outcomes, benefits, costs, risks, and satisfaction2.
