Closing a project helps prevent:

making the same errors over and over in new projects and goals
delivering finished goods or outputs without special assistance or resources
failing to identify the group or individuals who will be responsible for owning and maintaining the solution after delivery
posing liability problems as a result of missed payments, deadlines, or deliveries
Maintaining a well-defined project closing plan enables you to effectively hand off your solution to the client.

or final user. The final stakeholders are given the knowledge, tools, and training necessary to properly manage and use the product thanks to this process.

The project closure procedure also guarantees that the project is formally finished and is no longer regarded as a project, enabling you to transfer control to the appropriate team in responsibility of managing and maintaining the project’s results.

You reduce risks, raise client happiness, and make sure everyone is on the same page by formally completing a project. In other words, project closure is a step that must be completed.
