Which of the following ADM phases is where SBBs first appear in the ADM cycle?

In the context of the Architecture Development Method (ADM) within TOGAF, Solution Building Blocks (SBBs) first appear in Phase D, which focuses on Technology Architecture. During this phase, the architecture team defines how the architectural components will be realized through various solutions.

SBBs represent the physical aspects of the architecture design and include software and hardware components that will be utilized to implement the architecture. It is in this phase that the detailed specifications for these components are developed, creating a bridge between the conceptual architecture and the actual implementation.

Understanding that SBBs emerge in Phase D is crucial, as it signifies the transition from high-level architecture to tangible solutions that can be built and deployed. This phase ensures that any required technology components are identified and assessed, which is essential for achieving the desired architectural outcomes that have been established in the earlier phases of the ADM cycle.
