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.
The table describes the iterative cycle of defining requirements, identifying gaps, and creating solutions that occurs throughout the architecture development phases of the TOGAF ADM. This cycle is most prominent in:
Phase B (Business Architecture):
Develop the Business Architecture, identifying gaps between the baseline and desired business capabilities, processes, and information flows.
Define work packages to address these gaps and realize the target business architecture.
Phase C (Information Systems Architectures):
Develop the Data and Application Architectures to support the Business Architecture.
Identify gaps between the baseline and target information systems architectures.
Define work packages to address these gaps and realize the target data and application architectures.
Phase D (Technology Architecture):
Develop the Technology Architecture to support the Data and Application Architectures.
Identify gaps between the baseline and target technology architectures.
Define work packages to address these gaps and realize the target technology architecture.

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 Architecture Requirements Repository within the TOGAF Architecture Repository holds the architecture requirements that have been agreed with the Architecture Board. Here's a detailed explanation:
* Architecture Requirements Repository:
* This repository is a part of the larger Architecture Repository in TOGAF, which is used to store and manage all the artifacts related to the architecture.
* Content of the Repository:
* Agreed Requirements: It includes the architecture requirements that have been formally reviewed and agreed upon by the Architecture Board. These requirements are essential for guiding the development and implementation of the architecture.
* Governance and Compliance: The repository ensures that these requirements are accessible and can be used to enforce governance and compliance throughout the architecture development process.
* TOGAF ADM Phases:
* Phase A: Architecture Vision: Initial requirements are identified and refined.
* Phase B, C, D: Requirements are further detailed and agreed upon.
* Architecture Governance: Throughout these phases, the agreed requirements are stored in the repository to ensure they guide the architecture work and are adhered to.
* Purpose and Benefits:
* Centralized Repository: Having a centralized repository for agreed requirements ensures that all stakeholders have access to the current and approved requirements, facilitating better coordination and compliance.
* Traceability: It provides traceability of requirements throughout the architecture development lifecycle, ensuring that all decisions and designs are aligned with agreed requirements.
In summary, the Architecture Requirements Repository holds the architecture requirements that have been agreed with the Architecture Board, providing a centralized and authoritative source for guiding architecture development and ensuring compliance.

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.
