TOGAF Practice Exam 2025 – The All-in-One Guide to Master The Open Group Architecture Framework!

System Building Blocks (SBBs) are introduced in Phase D of the Architecture Development Method (ADM) in TOGAF. This phase focuses on Technology Architecture, which involves defining the technology components needed to support the proposed architecture. SBBs are critical in this context, as they represent specific components or services that will be used to implement the architecture.

During Phase D, architects identify and detail the SBBs required to fulfill the architectural vision articulated in earlier phases, such as Business Architecture and Information Systems Architecture. This phase also emphasizes ensuring that the SBBs align with the overall architecture and deliver the necessary functionality while adhering to quality standards and compliance requirements.

Understanding this phase's role in the overall ADM cycle is crucial, as it serves as the foundation for determining how the various building blocks will come together to realize the architecture outlined in previous phases.
