Which component provides a framework for comparing established architecture with desired changes?

The correct choice is associated with Gap Analysis. This component is specifically designed to identify the disparities between the current state of an architecture and the desired future state. By performing a Gap Analysis, organizations can assess what aspects of their current architecture do not meet the requirements for future needs or goals, effectively allowing them to pinpoint areas for improvement and transformation.

This process involves evaluating existing capabilities, resources, and processes against the strategic objectives and determining the necessary changes required to bridge the gap. Through this systematic comparison, stakeholders can make informed decisions about prioritizing changes and allocating resources effectively to achieve their architectural vision.

In contrast, the other options serve different purposes within TOGAF. The Architecture Repository is a storage space for architectural artifacts, while the Governance Log is related to the management of compliance and decisions in architecture governance. The Architecture Landscape provides a visual representation of the various architecture layers and domains rather than focusing directly on the comparison of existing and desired states.
