When considering the scope of an architecture, what dimension considers to what level of detail the architecting effort should go?

In the TOGAF standard, scoping an architecture effort involves four specific dimensions: Breadth, Depth, Time Period, and Architecture Domains. "Depth" specifically refers to the level of detail to which the architecting effort should go. This determines whether the architecture is developed at a high-level strategic, intermediate segment, or highly detailed capability level.

A. Project: This is not a standard scoping dimension in TOGAF; projects are vehicles for delivering and implementing the architecture.
B. Breadth: Refers to the extent of the enterprise covered (e.g., full enterprise vs. a specific division), not the level of detail.
D. Architecture Domains: Refers to the subject areas covered (Business, Data, Application, Technology), not the level of detail.
