TOGAF's ADM (Architecture Development Method) is designed to be iterative at multiple levels: over the whole process, between phases, and within phases. This iterative approach allows for continuous refinement and improvement of the architecture, ensuring it remains aligned with changing business needs and technological advancements. Iteration helps in managing complexity and facilitates incremental development, enabling architects to revisit and adjust their work as new information and insights emerge.

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.

When developing the Architecture Vision, it is essential for the architect to examine and search for Value Streams and Business Capabilities. Here’s a detailed explanation:

Architecture Vision Phase (Phase A):

The Architecture Vision phase sets the overall direction and context for the architecture project. It defines the scope and vision for the future state architecture and establishes a shared understanding among stakeholders.

Value Streams:

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

Importance: Understanding value streams helps in aligning the architecture with business processes and ensuring that the architecture supports the delivery of value.

Business Capabilities:

Definition: Business capabilities define what an organization needs to be able to do to achieve its business objectives. They represent the core functions or abilities of the organization.

Importance: Identifying and understanding business capabilities is crucial for ensuring that the architecture addresses the critical functions of the business and supports its strategic goals.

TOGAF ADM References:

Phase A: Architecture Vision: In this phase, the architect examines value streams and business capabilities to understand the current state and define the desired future state. This helps in creating an architecture vision that is aligned with business objectives and supports value creation.

Strategic Planning: Value streams and business capabilities provide a foundation for strategic planning, ensuring that the architecture is designed to support key business activities and capabilities.

In summary, when developing the Architecture Vision, examining value streams and business capabilities is essential for understanding how the organization delivers value and ensuring that the architecture supports critical business functions and strategic 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.
