In which phase of the TOGAF ADM are the assessments of migration project dependencies and costs performed?

The correct answer is found in Phase F of the TOGAF Architecture Development Method (ADM), which focuses on the migration planning process. During this phase, the assessments of migration project dependencies and costs are conducted. This is crucial because it involves creating a detailed plan for transitioning from the current state of the architecture to the desired target state.

In Phase F, stakeholders evaluate various factors such as existing systems, dependencies among different projects, the resources required, and cost implications. This ensures that the migration strategy is not only feasible but also aligns with the business objectives and available resources for successful implementation. By addressing these dependencies and costs early in the migration planning, organizations can minimize risks and avoid potential pitfalls in executing their architecture vision.

The other phases mentioned each have distinct objectives: Phase E deals with opportunities and solutions, Phase G focuses on implementation governance, and Phase H involves architecture change management. These phases contribute to the overall architectural development but do not specifically emphasize the detailed migration assessment that is central to Phase F.
