In the TOGAF ADM (Architecture Development Method), Phase B is the Business Architecture phase. During this phase, the information map, which represents the relationships and flow of information within the business, is linked to other business blueprints. This linkage is crucial to ensure that the business architecture is aligned with the data and information needs of the organization, providing a foundation for the development of subsequent architecture domains (Data, Application, and Technology Architectures).

According to the TOGAF Business Capabilities Guide V2, a business capability is defined as "the expression or the articulation of the capacity, materials, and expertise an organization needs in order to perform core functions"5. A business capability can be decomposed into four elements: roles, information, processes, and technology5. In the given example, A represents roles and C represents information.

In the context provided in the image, 'A' refers to the roles involved in the recruitment management process, which in this case is the 'User: Recruiter' and the 'Stakeholders: Manager, Candidate Employee'. 'C' refers to the information or data aspects of the process, which includes 'Candidate/Applicant Details', 'Position Descriptions', 'Recruitment Agency Data', and 'Industry Standard Role Definitions'. Thus, 'A' corresponds to 'Roles' and 'C' to 'Information'.

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.

TOGAF defines an “Enterprise” as any collection of organizations or alliances working toward shared goals, such as in consortiums or partnerships. This scope allows the architecture to address cross-organization processes and infrastructures for collaborative endeavors.

References: TOGAF Standard, Definition of an Enterprise.

TOGAF defines anEnterpriseas any collection of organizations that has a common set of goals. This definition is intentionally broad and can encompass various types of entities, including:

Single organizations:A traditional company or corporation with a unified structure and goals.

Groups of organizations:This could include:

Public sector:Government agencies, military branches, or international collaborations like the United Nations.

Private sector:Consortiums, industry alliances, supply chains, or joint ventures where multiple businesses work together towards shared objectives.

The key characteristic of an enterprise is the shared set of goals that drives its activities and architecture.
