In the provided diagram, item A refers to the Architecture Repository, which is a part of the TOGAF framework where all the architecture assets are stored. This includes the architectural models, patterns, architecture descriptions, and other artifacts relevant to the architecture. Item B is labeled as the Governing Board, which is likely referring to the Architecture Board or a similar governance structure responsible for oversight and decision-making regarding the enterprise architecture. Item C refers to Enterprise Capability, which encompasses the processes, tools, skills, and other capabilities that enable the architecture function within the enterprise.

Risk is defined as the effect of uncertainty on objectives. It can be positive or negative depending on whether it enhances or hinders the achievement of objectives. Threat is a potential cause of risk that could have a negative impact on objectives. Continuity is the ability to maintain or resume normal operations after a disruption or disaster. Vulnerability is a weakness or exposure that could be exploited by a threat to cause harm or damage.

In a business scenario, business capabilities and value streams are modeled when identifying the business and technology environment. Here’s a detailed explanation:

Business Scenarios in TOGAF:

Business scenarios are used to capture and describe the business requirements, providing a context for the architecture development. They help in understanding the business environment, identifying problems, and defining desired outcomes.

Identifying the Business and Technology Environment:

Business Capabilities: During this phase, the architect identifies the key business capabilities required to achieve the business objectives. These capabilities represent what the organization needs to be able to do.

Value Streams: Value streams are also identified and modeled to understand how value is delivered to customers and stakeholders. They provide a high-level view of the end-to-end processes that create value.

TOGAF ADM References:

Phase A: Architecture Vision: In this phase, understanding the business and technology environment is crucial for defining the architecture vision. Modeling business capabilities and value streams provides a foundation for this understanding.

Phase B: Business Architecture: This phase involves a detailed analysis of business capabilities and value streams to ensure that the architecture supports the business strategy and objectives.

Importance:

Contextual Understanding: By modeling business capabilities and value streams, architects gain a comprehensive understanding of the business and technology environment. This helps in aligning the architecture with business needs and ensuring that it supports value creation.

Strategic Alignment: Identifying and modeling these elements ensures that the architecture is aligned with the strategic goals of the organization and supports its key business activities.

In summary, business capabilities and value streams are modeled when identifying the business and technology environment, providing a comprehensive understanding of how the organization operates and how the architecture can support its objectives.

Business capabilities in TOGAF are defined as the ability of an organization to achieve a specific purpose or outcome. The components that make up a business capability typically include:

Roles: The responsibilities and positions within the organization that support the capability.

Processes: The activities and workflows that are essential to the functioning of the capability.

Information: The data and knowledge necessary for the capability to operate effectively.

Resources: The assets, such as people, technology, and materials, required to support the capability.

This comprehensive definition ensures that each capability is fully understood in terms of the resources and activities required to deliver its intended outcomes.

According to the TOGAF standard, business models are used to understand and describe the business itself, including its organization, its objectives, and how it operates. This understanding is crucial when defining an enterprise architecture as it provides a frame of reference. Business models help in identifying new capabilities that the business must develop to achieve its future state as outlined in the target business model. These capabilities may be processes, information, or technologies that the business must adopt or adapt to fulfill the strategic objectives and deliver value. TOGAF emphasizes the alignment of IT with business strategy, and the business model serves as a key link in ensuring that the capabilities delivered by the enterprise architecture will enable the desired business outcomes.

The technique shown in the example is called heat mapping. It is a technique that can be used to show a range of different perspectives on a business capability map, such as maturity, effectiveness, performance, and value or cost contribution of each capability to the business2. Different attributes determine the colors of each capability on the business capability map. Heat mapping can help to identify strengths, weaknesses, opportunities, and threats in the business architecture.

Table 3: Heat Map for ABC Company’s Business Capabilities

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.

In the context of a value stream within TOGAF, a value stream stage represents a segment of the overall process that delivers value to stakeholders. Each stage has specific characteristics and elements that help define its progress and completion. The "exit criteria" is a key element that describes the end state condition, denoting the completion of a value stream stage. Here’s how TOGAF defines and uses these concepts:

Value Stream Definition:

A value stream represents an end-to-end collection of activities that create a result for a customer, stakeholder, or end-user. It provides a visual representation of how value is delivered.

Value Stream Stages:

Each value stream consists of multiple stages, each contributing to the overall value delivery. These stages need to be clearly defined to ensure the value stream can be effectively managed and improved.

Exit Criteria:

Definition: Exit criteria are the conditions that must be met to signify the completion of a value stream stage. These criteria ensure that all necessary tasks have been completed and that the output meets the required quality and performance standards.

Purpose: By defining exit criteria, organizations can ensure that each stage of the value stream is completed before moving to the next, maintaining quality and consistency across the process.

TOGAF References:

Phase B: Business Architecture: In this phase, value streams and their stages are modeled. Defining exit criteria for each stage helps in managing transitions and ensuring that each part of the value stream is delivering the intended value.

In summary, the exit criteria define the end state condition of a value stream stage, ensuring that all necessary tasks are completed and quality standards are met before proceeding to the next stage.

When developing a Business Architecture, TOGAF provides guidance on how to leverage existing architecture descriptions to build a comprehensive and accurate Baseline Description. Here’s a step-by-step explanation:

Existing Architecture Descriptions:

Existing architecture descriptions provide valuable insights into the current state of the enterprise’s architecture. These descriptions can include documentation of processes, systems, technologies, and organizational structures.

Baseline Description:

The Baseline Description represents the current state of the enterprise architecture. It serves as the starting point for developing the Target Architecture and planning the transition from the current state to the future state.

Using Existing Descriptions:

Review and Analyze: Existing architecture descriptions should be reviewed and analyzed to understand the current state accurately. This involves identifying all relevant artifacts, documents, and data.

Integration into Baseline: The information from the existing descriptions should be integrated into the Baseline Description. This ensures that the Baseline accurately reflects the current state, providing a solid foundation for future planning.

Gaps and Opportunities: By using existing descriptions, architects can identify gaps in the current architecture and opportunities for improvement. This helps in formulating a more effective Target Architecture.

TOGAF ADM References:

Phase A: Architecture Vision: This phase involves establishing the architecture vision, which includes defining the scope and approach for the Baseline Description.

Phase B: Business Architecture: During this phase, the Baseline Business Architecture is developed using existing architecture descriptions as a key input.

In summary, using existing architecture descriptions as the basis for the Baseline Description ensures that the current state is accurately documented, providing a reliable foundation for developing the Target Architecture and planning the transition.

The need to govern Enterprise Architecture is supported by the fact that best practice governance enables the organization to control value realization. Here’s a detailed explanation:

Enterprise Architecture Governance:

Definition: Governance in the context of Enterprise Architecture (EA) involves establishing processes, roles, and responsibilities to ensure that the architecture is developed and maintained in alignment with the business strategy and objectives.

Importance of Governance:

Control and Accountability: Effective governance ensures that architecture activities are controlled and aligned with business priorities. It establishes accountability for architectural decisions and outcomes.

Value Realization: Governance mechanisms ensure that the architecture delivers value to the organization by aligning with strategic goals, optimizing resource usage, and ensuring that architecture initiatives are completed successfully.

TOGAF References:

Architecture Governance Framework: TOGAF provides a framework for architecture governance, including guidelines for establishing governance structures, processes, and tools to manage architecture activities effectively.

ADM Phases: Governance is integrated into all phases of the ADM to ensure that architecture development is controlled and aligned with business needs. This includes monitoring progress, managing risks, and ensuring compliance with architecture principles and standards.

Best Practices:

Continuous Improvement: Best practice governance involves continuous monitoring and improvement of the architecture processes to ensure they remain effective and deliver the desired outcomes.

Stakeholder Engagement: Effective governance ensures ongoing engagement with stakeholders, ensuring their needs and concerns are addressed, and maintaining alignment with business objectives.

In summary, the need to govern Enterprise Architecture is supported by the fact that best practice governance enables the organization to control value realization, ensuring that architecture initiatives are aligned with strategic goals and deliver tangible benefits.

In the TOGAF ADM cycle, Phase A, the Architecture Vision phase, is where the architect would locate existing architecture descriptions to create an information map. This phase involves understanding the strategic context for the architecture work, defining the scope, identifying stakeholders, creating the Architecture Vision, and obtaining approvals to proceed with the work. Part of this involves reviewing existing documentation to understand the current state of the architecture and the information that is already available, which would be useful for creating an information map.

 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.

The purpose of Enterprise Architecture, within the context of TOGAF, is to establish a clear and comprehensive blueprint for how an organization can effectively achieve its current and future objectives through a structured approach. Enterprise Architecture guides effective change by providing a long-term view of the organization's processes, systems, and technologies so that individual projects can build capabilities that fit into a cohesive whole. It helps to ensure that IT investments are aligned with business goals, supports the management of complex IT landscapes, and provides a systematic approach for the adoption of emerging technologies. Essentially, it acts as a strategic framework that facilitates the translation of business vision and strategy into effective enterprise change.

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.

Business models are essential tools within TOGAF for providing different perspectives on the business operations, strategies, and value propositions. Here’s a detailed explanation:

Purpose of Business Models:

Business models are designed to represent various aspects of the business, such as value creation, delivery, and capture mechanisms. They provide a structured way to analyze and understand the business.

Different Viewpoint:

Cross-Check Assumptions: Business models offer a different viewpoint that helps in validating and cross-checking assumptions made about the business. By presenting a visual and structured representation of the business, these models enable stakeholders to identify gaps, inconsistencies, and areas that need further analysis.

Holistic Understanding: They help in gaining a holistic understanding of how different components of the business interact, which is crucial for ensuring that the enterprise architecture aligns with the business strategy and goals.

TOGAF References:

Phase A: Architecture Vision: During this phase, business models are used to articulate the vision and scope of the architecture effort. They help in ensuring that all assumptions are validated and that the architecture aligns with business objectives.

Phase B: Business Architecture: Business models are also utilized in this phase to analyze business capabilities, processes, and value streams. They provide a different viewpoint that aids in identifying areas for improvement and ensuring alignment with the strategic intent.

In summary, business models provide a different viewpoint that helps cross-check assumptions, ensuring that the enterprise architecture is aligned with the business strategy and objectives.

The purpose of this activity is to identify which business capabilities (out of the total set of capabilities) are critical to delivering stakeholder value, and therefore which ones need to be performed to a sufficient standard of quality to meet stakeholder expectations. It also helps to identify those business capabilities that do not contribute toward any of the core value streams, and which may be eliminated from the business.

The primary purpose of mapping capabilities to value stream stages within the TOGAF framework is to analyze how each capability contributes to delivering value to the customer. This process helps to identify:

Capabilities essential for value creation: These are the capabilities that directly contribute to the activities within the value stream and are critical for delivering customer value.

Capabilities with indirect or unclear contributions: These may require further investigation to determine their role in the value stream.

Non-contributing capabilities: These capabilities do not play a role in the value stream and may be candidates for elimination or optimization to improve efficiency and reduce costs.

Organization mapping is a technique used to represent the structure and relationships within an organization. Here’s a detailed explanation of its benefits, particularly for strategic planning:

Organization Mapping:

Organization maps visually represent the hierarchical structure of an organization, including departments, teams, and reporting relationships. They provide insights into how the organization is structured and how different parts interact.

Benefits for Strategic Planning:

Alignment with Strategy: An organization map helps in aligning organizational structure with strategic goals. By understanding how the organization is structured, leaders can ensure that resources are allocated efficiently and that the organizational design supports the strategic objectives.

Identifying Gaps and Overlaps: Organization maps highlight areas where there might be gaps or overlaps in roles and responsibilities. This information is crucial for making strategic decisions about restructuring or reallocating resources.

Improving Communication: By clearly depicting the organizational structure, these maps improve communication and collaboration within the organization. This is particularly important for strategic planning, as it ensures that all parts of the organization are aligned and working towards the same goals.

TOGAF References:

Phase B: Business Architecture: Organization mapping is a key activity in this phase, where the current organizational structure is analyzed to ensure it supports the business strategy and architecture vision.

Strategic Planning: TOGAF emphasizes the importance of aligning the business architecture with strategic planning. Organization maps are tools that facilitate this alignment by providing a clear representation of the organizational structure.

In summary, organization mapping improves strategic planning by providing a clear, visual representation of the organizational structure, helping to align resources and design with strategic goals.

In TOGAF, the dimensions for scoping an architecture are Breadth (coverage across the organization), Depth (level of detail), Time Period (horizon of the architecture), and Architecture Domains (the four architecture domains of Business, Data, Application, and Technology). These dimensions ensure comprehensive scoping and contextual alignment.

References: TOGAF Standard, Chapter on Scoping the Architecture.

According to TOGAF, defining the scope of an architecture involves considering these four key dimensions:

Breadth: This refers to how much of the enterprise is covered by the architecture. It defines the boundaries of the architecture, which could range from a single department to the entire organization, or even extending to external partners.

Depth: This dimension determines the level of detail included in the architecture. It can range from high-level conceptual models to detailed specifications of individual components.

Time Period: This specifies the timeframe for the architecture, including the intended lifespan of the architecture and any planned phases or iterations. It addresses questions like "What is the architecture for now?" and "What should the architecture look like in the future?"

Architecture Domains: This dimension defines which of the four architecture domains (Business, Data, Application, Technology) are included in the scope. The selection of domains depends on the specific needs and objectives of the architecture development effort.

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.

https://pubs.opengroup.org/togaf-standard/adm-techniques/chap10.html

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.

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.

An information map is most closely related to a Business Capability Map in the sense that both are tools used to visualize and understand different aspects of an enterprise's architecture. While an information map focuses on the relationships and flow of information within the organization, a Business Capability Map outlines the abilities and capacities the business possesses. Both are used to analyze and design architectures that support the business's objectives.

The TOGAF standard covers the development of four architecture domains: Business, Data, Technology, and Application. The Application Architecture domain defines the applications required to process the data and support the business functions.

The TOGAF standard describes the development of four architecture domains, which are considered its pillars. These are Business, Data, Technology, and Application. The Application Architecture domain provides a blueprint for the individual application systems to be deployed, their interactions, and their relationships to the core business processes of the organization.

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.

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.

The relationship between business models and business architecture is that while business models provide a high-level description of business elements such as customers, markets, and the economic rationale of the business, the business architecture takes this model and breaks it down into more detailed descriptions. It identifies the core functional components and their relationships, which describe how the business operates, the roles involved, the information flowing through the business, and the technology supporting business activities.

In TOGAF ADM, Phase B is the Business Architecture phase where the architect should locate existing architecture descriptions to create an information map. This phase involves developing a detailed understanding of the business environment, including business processes, roles, and information flows. Existing architecture descriptions provide a baseline for identifying how information is currently managed and how it can be optimized to support business objectives.

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.

The chart depicted is a Gantt chart, which typically represents the schedule for project activities. In the context of TOGAF's ADM, it is used to illustrate the sequence and interdependencies of tasks across different phases of architecture development. The ADM is an iterative cycle that includes various phases, from the preliminary phase, through architecture vision, business, information systems, and technology architectures, to opportunities and solutions, migration planning, implementation governance, and architecture change management. Each phase must be conducted in a sequence to ensure that the outputs of one phase feed into the next, thereby producing a coherent and structured architecture.
