In which ADM phase are the Transition Architectures defined in Phase E confirmed with the stakeholders?

In the Architecture Development Method (ADM) of TOGAF, Phase E, which focuses on Opportunities and Solutions, involves the development of transition architectures, identifying the various work packages and building blocks needed to transition from the baseline to the target architecture. However, it is in Phase F that these transition architectures are confirmed with stakeholders.

During Phase F, the focus shifts to managing the migration planning process, ensuring that the transition architectures defined in Phase E are validated, prioritized, and aligned with stakeholder expectations and requirements. This is crucial because stakeholder approval is essential before proceeding with actual implementation steps in further phases.

Moreover, confirming these transition architectures in Phase F ensures that all stakeholders have a clear understanding of the proposed changes and agree on how to move forward, thus minimizing risks and enhancing the chance of successful implementation.

Phases G and H deal with implementation and governance, which are subsequent to confirming the transition architectures, making them less relevant for the specific confirmation process with stakeholders.
