Phase 3 focuses on full organizational rollout and change management.

• A. Phase 3
• B. Phase 0
• C. Phase 1
• D. Phase 2

Answer: (A)

Phase 3 is the stage where the solution is deployed across the entire organization, and it is accompanied by structured change management. This means training users, communicating the new processes, updating governance and support structures, and actively guiding adoption so the new way of working sticks. The emphasis on change management here reflects the reality that, once the technical rollout is ready, broad adoption hinges on people embracing and sustaining the change. Earlier phases are about planning, validating, and piloting, while Phase 3 ensures the rollout is complete and integrated into everyday practice.
