Explanation

In TOGAF, existing legacy systems and processes that will continue to be used in the future are classified as Re-usable Building Blocks (RBBs). They represent existing assets from the current (Baseline) Architecture that are valuable enough to carry forward into the Target Architecture. This distinguishes them from Architecture Building Blocks (ABBs), which are abstract and technology-independent, and Solution Building Blocks (SBBs), which are specific product or technology implementations rather than inherited legacy components.
