There should be a matching confirmation where work has been allocated to individuals or teams in order to ensure work has been completed and approved. Once approved, any further changes must pass through change control. This should be done automatically as part of the configuration management being used.
PRINCE2 recommends:
✔ Ensure that the Team Manager has completed the work defined by the Work Package(s)
✔ Check that the Quality Register entries relating to the product(s) are complete
✔ Ensure that each product in the Work Package has gained its requisite approval (as defined in the quality responsibilities in its Product Description)
✔ Confirm that the Configuration Item Record for each approved product has been updated
✔ Update the Stage Plan to show the Work Package as completed.
