Phase A – creating a roadmap of dissatisfactions (what and why you don’t like), planning measures to correct the situation, determining means and limitations.
Phases B, C, and D (Business, Information business owner data package Systems, and Technology Architecture) involve developing a blueprint for the goals that the architectural vision should achieve.
Phases E (opportunities and solutions) and F (development of migration plans) – formation of a set of tools with the help of which the target BA will be created.
Phases G (Execution Management) and H (Business Architecture Change Management) provide for the completion of the cycle and the transition to the new.
