The deployment plan (cut-over plan) is an essential part of project management. The five main milestones are: strategic planning as early as possible, allocate time to teams for data conversion, write a detailed production plan, test the deployment plan with simulations, and be ready on D-day with contingent teams and the go/no-go process.
The post-implementation support phase is the last step of an IT project. Its objective is to ensure a smooth transition between teams. The success of this support depends on three key actions: choose the most competent staff, determine and categorize issues according to their type and severity, and carry out rigorous monitoring with all stakeholders. This phase often contributes to the acceptance of change.
