Transitioning a project to an operational state involves ensuring that all deliverables have been completed and meet the required standards. Reviewing the WBS with the project team is a good practice to confirm that all planned deliverables have been produced and validated. This step is crucial as it helps to ensure that the project has met its objectives and that all components are in place for the operational phase. It also allows for the identification of any remaining work that needs to be completed before the project can be closed out.
