Which one of the following statements about TOGAF Building Blocks is true?

The correct answer is C. The specification of a building block should be loosely coupled to its implementation. TOGAF states that a building block's specification should be loosely coupled to its implementation. This is a key design principle: it allows the same specification to be realized by different implementations, promoting flexibility and reuse. Option A is false - functional-level

Explanation

TOGAF states that a building block's specification should be loosely coupled to its implementation. This is a key design principle: it allows the same specification to be realized by different implementations, promoting flexibility and reuse. Option A is false - functional-level building blocks are Architecture Building Blocks (ABBs), not Solutions Building Blocks (SBBs). Option B is false - SBBs are selected in Phase E (Opportunities and Solutions), not Phases A-D. Option D is false - gap analysis identifies gaps between Baseline and Target Architectures, not specifically building blocks for reuse.
