This chapter describes the process of identifying delivery vehicles (projects, programs, or portfolios) that effectively deliver the Target Architecture identified in previous phases.

The objectives of Phase E are to:

1) Generate the initial complete version of the Architecture Roadmap, based upon the gap analysis and candidate Architecture Roadmap components from Phases B, C, and D.

2) Determine whether an incremental approach is required, and if so identify Transition Architectures that will deliver continuous business value.

3) Define the overall Solution Building Blocks (SBBs) to finalize the Target Architecture based on the ABBs.
