a) In phases, B, C and D, it is mentioned "Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Business, Application, Data or Technology Architectures". Is this "candidate architecture roadmap component" same as Transition Architecture of the Architecture Roadmap? If not, what is it? b) In phase E, it is mentioned, "Determine whether an incremental approach is required, and if so identify Transition Architectures that will deliver continuous business value". So, it is confusing, which phase defines the Transition architecture, phase E or phase B, C and D?
