In TOGAF, the dimensions for scoping an architecture are Breadth (coverage across the organization), Depth (level of detail), Time Period (horizon of the architecture), and Architecture Domains (the four architecture domains of Business, Data, Application, and Technology). These dimensions ensure comprehensive scoping and contextual alignment.

According to TOGAF, defining the scope of an architecture involves considering these four key dimensions:
Breadth: This refers to how much of the enterprise is covered by the architecture. It defines the boundaries of the architecture, which could range from a single department to the entire organization, or even extending to external partners.
Depth: This dimension determines the level of detail included in the architecture. It can range from high-level conceptual models to detailed specifications of individual components.
Time Period: This specifies the timeframe for the architecture, including the intended lifespan of the architecture and any planned phases or iterations. It addresses questions like "What is the architecture for now?" and "What should the architecture look like in the future?"
Architecture Domains: This dimension defines which of the four architecture domains (Business, Data, Application, Technology) are included in the scope. The selection of domains depends on the specific needs and objectives of the architecture development effort.
