In PM terms, when is a Project considered to be complete?

A project is considered complete when it has been successfully implemented and transitioned to the performing organization and approved by the Project Manager... in the project I used to work ,,, the project was completed when we went on line with production, however now it had to maintained... it is different building a building than planning in a production area ... the a production facility a project truly never gets completed ... just a different stage of PM starts.

In PM standards, the project is considered to be complete when the customer/sponsor accepts the project deliverables by signing off the acceptance agreement, then after that, all the project resources are archived and released after that.

When the archive is stored.

After disbursement of the Project related obligations; Handover the documentary evidences of project work and project office properties/assets,  finally submission of the completion report either by the recognized authority or by the sponsor.

A project is considered complete when it has been successfully implemented and transitioned to the performing organization and approved by the Project Sponsor. At this point in the project management lifecycle, the responsibilities of the Project Manager are to assess how closely the project met Customer needs, highlight what worked well, learn from mistakes made during the project, identify patterns and trends, derive ways to improve upon processes executed throughout the project, and, most importantly, communicate results. The purpose of Conduct Post-Implementation Review is to gather the information required to meet those responsibilities, and to present the information in a Post-Implementation Report.
