  Mapping is the process that turns a set of business capabilities into a structure that communicates the right amount of detail to different stakeholder groups. Here's a detailed explanation:

  Definition of Mapping:

  Mapping: In the context of business architecture, mapping refers to the process of visually representing the relationships between business capabilities and other elements such as processes, value streams, and organizational units. This

  helps in communicating the structure and interactions within the business.

  Purpose:

  Communication: Mapping provides a clear and structured way to communicate the details of business capabilities to different stakeholder groups. It ensures that each group receives the appropriate level of detail needed for their role and

  decision-making.

  Alignment: Helps in aligning business capabilities with strategic goals, processes, and organizational structure, ensuring that the architecture supports the overall business strategy.

  TOGAF References:

  Phase B: Business Architecture: During this phase, mapping is used to represent business capabilities and their relationships with other business elements. This helps in creating a coherent and comprehensive business architecture.

  Capability Mapping: TOGAF emphasizes the use of capability mapping to understand and analyze how different capabilities support business processes and value streams.

  Benefits:

  Clarity and Understanding: Mapping provides a visual representation that enhances clarity and understanding of the business architecture. It helps stakeholders see the big picture and understand how different parts of the business fit

  together.

  Stakeholder Engagement: By providing the right amount of detail to different stakeholders, mapping ensures effective engagement and collaboration across the organization.

  In summary, mapping is the process that turns a set of business capabilities into a structure that communicates the right amount of detail to different stakeholder groups, facilitating clarity, understanding, and alignment.

• Question 83:

  Consider the following chart: Which important concept for Enterprise Architecture Practitioners does it illustrate?

  

  A. ADM phases must be run in a sequenced approach to produce the Architecture

  B. An Enterprise Architecture must be developed in phases with a limited fixed duration.

  C. ADM phases must be run simultaneously until the relevant information has been produced

  D. Enterprise Architects must use Gantt charts to communicate with Stakeholders.

  Correct Answer: C

  Reference: https://pubs.opengroup.org/togaf-standard/adm-practitioners/adm-practitioners_5.html The Gantt shows the inter-dependent nature of EA requires all ADM phases that develop a candidate architecture and test it for acceptance to be open simultaneously. The ADM phases stay open to address the information required; once it is provided they close.

• Question 84:

  Complete the sentence An information map is a_______________________________________.

  A. description of the business units that use capabilities and participate in value streams

  B. target description of information assets needed to support the business

  C. representation of where the business information is held within the enterprise

  D. collection of information concepts and their relationships to one another

  Correct Answer: D

  An information map is essentially a collection of information concepts along with their relationships. It's a visual representation that shows how various types of information are related and used throughout the organization. This can include data entities, their attributes, and the flow of data between different business processes or systems. Information mapping helps in understanding the structure of an organization's data and is a key part of the information system architecture within TOGAF's content framework.

• Question 85:

  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. Relationship Mapping

  B. Capability Mapping

  C. Perspective Analysis

  D. Gap Analysis

  Correct Answer: A

  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.

  This modeling technique is referred to as Relationship Mapping. It's used to relate business capabilities to organizational units to highlight areas of duplication and redundancy, as well as to indicate where capabilities are being performed well (green), where there are potential issues (yellow), and where there are significant problems or gaps (red). This visualization helps in understanding the alignment between organizational units and capabilities, and where improvements or changes may be needed.

• Question 86:

  Which of the following best describes a business capability map?

  A. A self-contained view of the business that is independent of organizational structure, business processes, systems and applications.

  B. The highest-level description of an organization, covering all missions and functions of the business.

  C. A holistic representation of capabilities, including end-to-end delivery value, and the relationships between these capabilities.

  D. A reference model that provides a c onceptual definition of all the key building blocks within a business architecture

  Correct Answer: C

  A business capability map is a comprehensive representation that showcases an organization's abilities in a structured manner. It identifies and illustrates the various business capabilities that allow the enterprise to function and deliver value. These capabilities are often defined independently of the organizational structure, processes, or technology, focusing instead on what the business does and can do. This map encompasses the end-to-end value delivery and how different capabilities interrelate and support one another, thus providing a holistic view of the business's functional abilities.

• Question 87:

  Consider the following example value stream:

  

  What does this show?

  A. The service "Acquire Retail Product" consists of five events

  B. The value stream consists of five business capabilities.

  C. A series of five subprocesses that makeup the value stream

  D. A decomposition into a sequence of value-creating stages.

  Correct Answer: D

  The example value stream shown, labeled "Acquire Retail Product," represents a decomposition into a sequence of stages that collectively create value. Each stage, such as "Advertise Channels," "Display Products," "Enable Selection," "Process Payment," and "Deliver Product(s)," is a step in the overall process that contributes to the final outcome, which in this case is the acquisition of a retail product by the customer. Value streams are utilized in business architecture to model the flow of value through an organization from the initial customer demand to the final delivery of the product or service.

• Question 88:

  What process is used to decompose a set of business capabilities to communicate more detail?

  A. Layering

  B. Sorting

  C. Mapping

  D. Leveling

  Correct Answer: D

  The process used to decompose a set of business capabilities to communicate more detail is leveling6. Leveling is a technique that can be used to break down a business capability into sub-capabilities at lower levels of granularity6. Leveling can help to provide more clarity and specificity about what a business capability entails and how it supports the business goals and objectives6. Leveling can also help to identify dependencies, gaps, overlaps, or redundancies among business capabilities6.

• Question 89:

  Consider the diagram of an architecture development cycle.

  

  Which description matches the phase of the ADM labeled as item 2?

  A. Conducts Implementation planning for the architecture defined in previous phases

  B. Provides architectural oversight for the implementation

  C. Operates the process of managing architecture requirements

  D. Establishes procedures for managing change to the new architecture

  Correct Answer: B

  The Architecture Development Method (ADM) is the core process of TOGAF which outlines a method for developing and managing the lifecycle of enterprise architecture. Considering the phases of the ADM, the item labeled as '2' in the provided architecture development cycle diagram likely corresponds to the 'Architecture Change Management' phase, which is responsible for providing ongoing architectural oversight and guidance to ensure that the implementation remains aligned with the architecture defined in the previous phases. This includes managing changes to the architecture in a controlled manner as the implementation progresses and ensuring that the architecture continues to meet the business needs.

• Question 90:

  Which statement best describes iteration and the ADM?

  A. The ADM is sequential. Iteration is applied within phases.

  B. The ADM is iterative between phases B to D, and between Phases E and F.

  C. The ADM is iterative, over the whole process, between phases, and within phases.

  D. The level of detail is defined once and applies to all iterations.

  Correct Answer: C

  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.
