Which framework is primarily used for enterprise architecture?

TOGAF, or The Open Group Architecture Framework, is primarily used for enterprise architecture due to its comprehensive approach to designing, planning, implementing, and governing an enterprise information architecture. It provides a standardized methodology and framework for developing an enterprise architecture, emphasizing alignment with business goals and strategic objectives. TOGAF includes guidelines, best practices, and templates that organizations can utilize to create a well-structured architecture that meets their unique needs.

In essence, TOGAF aids organizations in capturing their current architecture's state, determining the desired future state, and successfully transitioning between these states. Its iterative process, known as the Architecture Development Method (ADM), allows for continuous improvement and responsiveness to change in a dynamic business environment.

Other options, while useful in their own contexts, do not serve the primary role of a comprehensive enterprise architecture framework. VMOST incorporates vision, mission, objectives, strategy, and tactics for strategic planning but doesn't focus specifically on architectural frameworks. RACI is a responsibility assignment matrix for clarifying roles and responsibilities within processes rather than a structure for architecture itself. POPIT, which stands for People, Organization, Processes, Information, and Technology, offers a way to visualize the structure of an organization but lacks the comprehensive framework that TOGAF provides.
