Which document is central to architecture compliance assessment in TOGAF?

The Implementation Governance Framework is central to architecture compliance assessment in TOGAF because it provides the structured approach and guidelines necessary for ensuring that implementation aligns with the established architectural vision and principles. This framework outlines the processes and governance structures that guide the development and execution of architecture implementation projects, ensuring that projects conform to the requirements of the architecture.

The Implementation Governance Framework includes principles, standards, and practices that govern the assessment of architectural compliance. It enables organizations to monitor progress during implementation and make necessary adjustments when deviations from the architectural vision occur. This oversight is crucial in maintaining the integrity of the architectural design and ensuring that the organization's needs are met throughout the implementation lifecycle.

The other documents mentioned play different roles in the architecture development process. The Architecture Vision Document primarily outlines the overarching goals and objectives of the architecture, while the Change Management Plan focuses on managing changes to the architecture. The Business Motivation Model is used for understanding the business reasons behind strategic initiatives, rather than assessing compliance against architectural standards. Therefore, the Implementation Governance Framework is the key element that directly supports compliance assessment.
