The PRIMARY function of COBIT Implementation Phase 7: How Do We Keep the Momentum Going is to provide an opportunity for which of the following?

The primary function of Phase 7, "How Do We Keep the Momentum Going?", is to sustain the governance system and embed a culture of continual improvement. A critical activity to achieve this is ensuring frequent and effective stakeholder communication. This includes reporting on the success of the initiative, reinforcing the value delivered, and communicating the need for ongoing improvement. This communication maintains stakeholder buy-in and reinforces new ways of working, which is essential for keeping the momentum going and starting the next improvement cycle.

A. Closing the loop for communication workflow: This is too narrow and procedural; the function is broader, focusing on communicating success and reinforcing the need for continuous improvement.
B. Documenting improvements in a prioritized action plan: This is an output of Phase 7 that serves as an input to the next implementation cycle, not the primary function of the phase itself.
