When a member terminates the use of a service, they may remain on-going requests and information to be returned. The operational closure must be legible, even if the overall relationship with the cooperative continues. The legal effects depend on the actual conditions and must be verified separately.
I propose to reconstruct what remains to be completed and what steps are needed. An activity may be terminated, transferred or cancelled under applicable agreements. The structure and the member should know the status of the performance avoiding that a generic communication interrupts the work without a management of outstanding matters.
Let's imagine a support service that keeps documents that are still usable from the store. An organised return can facilitate the continuity of work. Data management requires appropriate procedures and cannot be defined solely on the basis of operational convenience.
The closure should produce an understandable summary of completed activities and those still to be managed. Its value concerns the quality of the relationship and the possibility of avoiding subsequent misunderstandings. A service ends best when the exit path is recognizable from the start.
