In many ways, initiating the change project starts with the previous significant step, notably the Sourcing of the solution or provider. Prior steps should certainly line up the key change features through robust service schedules or go-live criteria. A proper initiation phase should get the project off to a great start and ensure the Project Brief and Project Plan are correctly compiled.
Delivering the project
Any form of change is tricky. It requires a robust plan of course, but also an approach which manages the change empathetically. Many people may be impacted by the changes. Matters such as TUPE should not be taken lightly. Many other variables can impact the course of a project and will need careful management to ensure the critical path is maintained appropriately.
