Correct Answer: D

Heat mapping is an analysis technique used in TOGAF to show a range of different perspectives on the same set of business capabilities. This technique involves visually representing data to highlight areas of importance or concern, such as performance levels, resource allocation, or risk exposure. Heat maps provide a clear and intuitive way to identify strengths, weaknesses, opportunities, and threats within the business capabilities, facilitating better decision-making and prioritization of improvement efforts.

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.

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.

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.

Correct Answer: B

In TOGAF, a business capability represents a high-level abstraction of what a business does, independent of how, why, or where the capability is used. Here's a detailed explanation:

Definition of Business Capability:

Business Capability: A business capability describes the capacity or ability of a business to act or achieve a specific outcome. It is an abstraction of the business functions, representing what the business does.

Key Characteristics:

What, Not How: A business capability focuses on what the business does, without delving into the specifics of how, why, or where it is implemented or utilized. This abstraction helps in maintaining a clear and consistent understanding across

the organization.

Independence: Business capabilities are designed to be independent of the organizational structure, processes, or systems that support them. This ensures that they remain stable even as the organization evolves.

TOGAF References:

Phase B: Business Architecture: In this phase, business capabilities are identified and mapped to understand the core functions of the business. This helps in aligning the architecture with business strategy and objectives. Capability-Based

Planning: TOGAF emphasizes capability-based planning, where business capabilities are used as the foundation for planning and decision-making.

Importance:

Strategic Alignment: Business capabilities provide a stable and consistent view of what the business does, which is crucial for aligning the architecture with strategic goals. Foundation for Analysis: By focusing on what the business does,

capabilities serve as a foundation for various analyses, including gap analysis, impact analysis, and capability maturity assessments.

In summary, a business capability delineates what a business does without an explanation of how, why, or where the capability is used, providing a stable and consistent foundation for strategic planning and architecture development.

Correct Answer: C

The table describes the steps involved in Phase B (Business Architecture), Phase C (Information Systems Architectures), and Phase D (Technology Architecture) of the TOGAF ADM5. These phases are responsible for developing the target architectures for each domain and identifying the gaps between the baseline and target architectures. The table shows the outputs and outcomes of each phase, as well as the essential knowledge required for each phase.

Correct Answer: A

One of the guidance for creating value streams is to start with customer-based value streams2. Customer-based value streams are those that describe how an enterprise creates and delivers value for its external customers2. Starting with customer-based value streams can help to ensure that the value streams are aligned with the customer needs and expectations, as well as the enterprise's value proposition and strategic objectives2. Customer-based value streams can also provide a foundation for identifying and defining other types of value streams, such as internal or partner-based value streams.

Correct Answer: B

Business models within the TOGAF standard are used to tailor the enterprise architecture to the specific needs and context of the business. They help in understanding how the business operates, its structure, and how it intends to achieve its goals, which is critical for ensuring that the enterprise architecture aligns with and supports the business objectives.

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.

Correct Answer: B

Business scenarios are most prominently used in Phase A (Architecture Vision) of the TOGAF ADM. In this phase, they help in discovering and documenting business requirements by providing detailed and realistic descriptions of business situations. Business scenarios help in identifying the key business drivers, goals, and challenges, ensuring that the architecture development is aligned with the actual needs of the business.
