In TOGAF, what does a Solution Building Block (SBB) refer to?

A Solution Building Block (SBB) in TOGAF refers to a service used to deliver a solution, typically built from one or more Architecture Building Blocks (ABBs). This concept emphasizes the modular and composable nature of architecture in a way that allows organizations to integrate various components to create a comprehensive and effective solution.

The SBB is important because it supports the implementation phase of architecture development by providing concrete building blocks that can be utilized in constructing applications, systems, or services. By being structured around ABBs, which provide the essential foundational elements in an architecture, SBBs ensure that the solutions are aligned with the high-level architectural vision while remaining flexible enough to address specific requirements.

This clear delineation allows organizations to map out the functionality and services required to fulfill business needs, making it easier to manage, maintain, and evolve the architecture over time. As a result, SBBs assist in ensuring consistency and standardization across the organization’s architecture landscape.
