In which part of the ADM cycle do building block gaps become associated with work packages that will address the gaps?

In Phase E (Opportunities and Solutions) of the TOGAF ADM, the gaps identified in the architecture domains during Phases B, C, and D are consolidated and analyzed. It is during Phase E that these building block gaps are grouped and associated with specific work packages and transition architectures that will address them. This process forms the basis of the initial Architecture Roadmap and determines how the target architecture will be practically delivered.

A. Phases G and H: Phase G governs the actual implementation, and Phase H manages changes to the architecture; they do not perform the initial grouping of gaps into work packages.
B. Phases F: Phase F (Migration Planning) finalizes the Implementation and Migration Plan based on the work packages that were already defined and prioritized in Phase E.
C. Phases B C and D: These phases identify the specific gaps between the Baseline and Target architectures within their respective domains, but they do not define the work packages to address them.
