What phase follows the Implementation Governance phase in TOGAF?

Following the Implementation Governance phase in TOGAF, the next phase is the Change Management phase. This phase is critical because it focuses on ensuring that the changes introduced during the implementation are effectively managed and aligned with the overall architecture framework. Change Management is essential for maintaining the integrity and continuity of the architecture post-implementation, supporting the organization in adapting to the changes made.

In the Change Management phase, the emphasis is placed on managing stakeholder engagement and addressing any resistance to change. This includes processes to facilitate ongoing communication, monitor the impact of the changes, and make necessary adjustments to ensure that the objectives of the architecture are met. Through effective change management, organizations can achieve smoother transitions, minimize disruption, and enhance the overall success of the architectural implementation.

The other choices represent different phases or realms within the TOGAF framework that do not directly succeed the Implementation Governance phase, thus making them incompatible with the sequence of phases outlined in the architecture development process.
