 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.

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.

In the TOGAF ADM (Architecture Development Method), Phase A, also known as the Architecture Vision phase, is critical for defining the problem to be solved and identifying the stakeholders, their concerns, and requirements. Here’s a detailed explanation:

Phase A: Architecture Vision:

Objective: The primary objective of Phase A is to establish a high-level vision of the architecture project. This includes defining the scope, identifying stakeholders, and understanding their concerns and requirements.

Stakeholder Identification: During this phase, all relevant stakeholders are identified. This includes business leaders, IT leaders, end-users, and other parties who have a vested interest in the architecture project.

Concerns and Requirements: Once stakeholders are identified, their concerns and requirements are gathered. This involves understanding their needs, expectations, and the issues they face that the architecture project aims to address.

Key Activities:

Problem Definition: Phase A focuses on clearly defining the problem or opportunity that the architecture project seeks to address. This sets the stage for developing the architecture vision and ensuring that the project aligns with business goals.

Developing the Architecture Vision: A key output of Phase A is the architecture vision, which provides a high-level overview of the desired future state. This vision is aligned with the business strategy and objectives.

Requirements Management: Phase A also involves establishing a requirements management process to ensure that stakeholder needs are captured, analyzed, and addressed throughout the architecture development process.

TOGAF References:

Phase A Deliverables: Key deliverables of Phase A include the Architecture Vision document, stakeholder map, and high-level requirements.

ADM Guidelines and Techniques: TOGAF provides guidelines and techniques for effectively conducting Phase A, including methods for stakeholder analysis, requirements gathering, and developing the architecture vision.

In summary, Phase A of the TOGAF ADM focuses on defining the problem to be solved, identifying stakeholders, understanding their concerns and requirements, and developing a high-level architecture vision that aligns with business objectives.
