According to TOGAF, the recommended dimensions used to define the scope of an architecture include all the following, except:

TOGAF defines four key dimensions for scoping an architecture effort to ensure it is focused and manageable. These dimensions are Breadth (the enterprise scope being covered), Depth (the level of detail to be modeled), Time Period (the timeframe for the architecture, including baseline, target, and transition states), and Architecture Domains (which of the Business, Data, Application, and Technology domains are included). "Subject Matter" is not one of the explicitly recommended dimensions for scoping an architecture according to the TOGAF framework.

A. Architecture Domains: This is a core dimension used to scope which of the four architecture types (Business, Data, Application, Technology) will be addressed.
B. Enterprise Focus: This is synonymous with "Breadth," which defines the parts of the enterprise to be covered by the architecture effort.
C. Level of Detail: This is synonymous with "Depth," a key dimension that determines how granular the architectural descriptions will be.
E. Time Period: This dimension is crucial for defining the baseline and target states and the duration of any transition architectures.
