Which document is important for validating architecture against requirements in TOGAF?

The Architecture Compliance Review is crucial for validating architecture against requirements in TOGAF. This document serves as a structured process to ensure that the architecture meets established standards and fulfills the specified requirements. During the compliance review, stakeholders assess how well the architecture aligns with the defined requirements, which assists in identifying any gaps or discrepancies that may exist.

Conducting these reviews helps ensure that the architectural framework is not only theoretically sound but also practically applicable and effective. This process is a vital part of maintaining the quality and integrity of the architecture throughout its lifecycle, ensuring that it continues to meet organizational needs and strategic objectives.

While the other documents, such as the Architecture Repository, Requirements Specification Document, and Change Management Log, play significant roles in the overall architecture development process, they do not specifically focus on the validation of architecture against requirements. The Architecture Repository serves as a storage for architectural artifacts, the Requirements Specification Document outlines the necessary requirements but does not validate them, and the Change Management Log tracks modifications rather than assessing compliance with the requirements. Thus, the Architecture Compliance Review is specifically designed for that validation purpose.
