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

The scope of an architecture is the extent and level of detail of the architecture work. The scope of an

architecture can be defined along four dimensions: project, breadth, depth, and architecture

domains. The project dimension considers the boundaries and objectives of the architecture project,

such as the time frame, budget, resources, and deliverables. The breadth dimension considers the

coverage and completeness of the architecture across the enterprise, such as the organizational

units, business functions, processes, and locations. The depth dimension considers the level of detail

and specificity of the architecture, such as the granularity, abstraction, and precision of the

architectural elements and relationships. The architecture domains dimension considers the aspects

or segments of the architecture, such as the business, data, application, and technology domains.

Therefore, the depth dimension is the one that considers to what level of detail the architecting

effort should go.
