Problem management: the work that happens after service is restored
Incident management ends when the service is back. Problem management is what nobody schedules — finding out why, and removing the cause.
Project closure hands over the work, releases the team and records what happened. What to complete, what to hand to whom, and why most projects never formally end.
Project closure is the set of things that have to happen for a project to be genuinely finished rather than merely quiet. Most projects do not get closed; they trail off, with two open issues nobody owns, a supplier invoice still to come, and a team that has drifted onto other work while remaining nominally assigned. The cost of not closing is not tidiness — it is that the budget stays open, the lessons are never captured, and nobody can say whether the thing actually worked.
Closure is where scope disputes surface, because it is the first moment anyone has to say the work is complete. That is not a reason to avoid it — the dispute exists either way, and having it while the team and the evidence are still available is considerably cheaper than having it in six months with a supplier who has moved on.
Ettex Boards is where the closure checklist belongs as a short list of items with owners, because closure fails as a document and works as a set of tasks somebody is assigned. Keep the acceptance record, the handover and the outstanding-issue decisions together, and put the benefits review on the calendar as a dated item rather than an intention. It links back to the project charter, which is where the success criteria you are now testing against were written. Ettex does not manage budgets or contracts — the financial and procurement closure steps happen in your finance system; what this holds is the list of them and whether they are done.
Yes, and often you should. What matters is that each open issue has a named owner outside the project and a decision recorded — transferring an issue is closure, leaving it unassigned is not.
The person or body that authorised the project, against the criteria in the charter. Sign-off by the project manager alone is self-certification and tends to be treated as such later.
Late enough for the benefits to be measurable, which is usually three to twelve months after go-live depending on what was promised. Set the date at closure; deciding later means never.

A postmortem that produces a beautifully written timeline and no completed actions has cost a team an afternoon and changed nothing.
A snagging list records the defects found before handover. Its value is entirely in the timing — the same defect is a five-minute fix before completion and an argument afterwards.
