Explanation
According to the PMBOK Guide, a project manager should manage the transition of the project deliverables to the operations team and ensure that they have the necessary skills andknowledge to support the new system. A project using a hybrid approach to migrate from a current system to a new and enhanced system in stages should include knowledge transfer sessions between the project and operations team at every stage. This can help the operations team to understand the features, functions, and benefits of the new system, as well as the potential issues, risks, and changes that may arise during the migration. This can also help the project team to obtain feedback, validation, and acceptance from the operations team. Including knowledge transfer sessions is the best option, as it can improve the readiness, confidence, and satisfaction of the operations team. Creating a lessons learned register, changing the project management plan, or preparing detailed documentation are not the best options, as they do not address the immediate concern of the operations team and may not provide enough information or interaction to ensure a smooth transition.
