According to the PMBOK Guide, 6th edition, one of the key processes of the Project Integration Management knowledge area is Close Project or Phase, which involves finalizing all activities across all of the project management process groups to formally complete the project or phase. One of the tools and techniques for this process is benefits transition, which involves transferring the ownership of the project's benefits to the assigned business owner or sponsor, who will be responsible for sustaining and enhancing the value of the project outcomes. By confirming ownership for ongoing value realization, the project manager can ensure that the project team members understand the benefits of the project features and how they will be measured and monitored after the project closure.
