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

The correct answer is C. Building Block specifications should be loosely coupled to implementation. Building Block specifications should be loosely coupled to implementation, meaning the specification (what it does) is defined independently from how it is implemented. This allows flexibility - the same Architecture Building Block (ABB) can be realized by different Solution…

Explanation

Building Block specifications should be loosely coupled to implementation, meaning the specification (what it does) is defined independently from how it is implemented. This allows flexibility - the same Architecture Building Block (ABB) can be realized by different Solution Building Blocks (SBBs). The other options are false: a good Building Block CAN be composed of other Building Blocks; ABBs are defined early (not first selected in Phase D); and custom developments are classified as SBBs, not ABBs.
