According to the PMBOK Guide, closing a project or phase is the process of finalizing all activities across all of the project management process groups to formally complete the project or phase1 One of the main outputs of this process is the final product, service, or result transition, which involves transferring the ownership and accountability of the project deliverables to the customer, sponsor, or other designated entity1 Another important output is the project documents updates, which involves archiving all the project documents following the organization’s accepted practices so that they can be used in other future projects1 Archiving the project documents ensures that the project information is properly stored, organized, and accessible for future reference, lessons learned, audits, or legal purposes2 Some examples of project documents that should be archived are the project charter, the project management plan, the project scope statement, the work breakdown structure, the project schedule, the project budget, the quality reports, the risk register, the issue log, the change log, the stakeholder register, the lessons learned register, and the project closure report12

In the given scenario, the project manager is instructed by the project sponsor to immediately close the project and to move on to another project. The project manager should complete the critical task of archiving all the project documents before closing the project. This will ensure that the project information is preserved and available for future use, and that the project closure is done in a systematic and consistent manner2

The other options are not the best choices for the following reasons:

Option A: Ensure that the whole team is appropriately recognized and organize a project farewell party to celebrate the project success and closure. This option suggests recognizing the project team and celebrating the project success and closure. While this is a good practice to motivate and appreciate the project team, it is not the most critical task that the project manager should complete before closing the project. The project manager should first ensure that the project deliverables are transferred to the customer or sponsor, and that the project documents are archived, before organizing any recognition or celebration events2

Option B: Update and close both the risk register and issue log with the latest updates, and save them in the organization’s project management information system (PMIS). This option suggests updating and closing the risk register and issue log, and saving them in the PMIS. While this is a necessary task to document and communicate the status and resolution of the project risks and issues, it is not the only task that the project manager should complete before closing the project. The project manager should also update and archive other project documents, such as the project charter, the project management plan, the project scope statement, the work breakdown structure, the project schedule, the project budget, the quality reports, the change log, the stakeholder register, the lessons learned register, and the project closure report12

Option D: Meet with the project sponsor and advise that the new project might be difficult to undertake because the current project is not yet complete. This option suggests meeting with the project sponsor and advising that the new project might be difficult to undertake because the current project is not yet complete. While this is a valid concern that the project manager should raise with the project sponsor, it is not the most critical task that the project manager should complete before closing the project. The project manager should first finalize all the activities and deliverables of the current project, and archive all the project documents, before moving on to another project2
