Because each incident is resolved and closed. The workaround works, everybody moves on, and the same fault is fixed forty times without anyone counting the cost of not fixing it once.
A problem is the underlying cause of one or more incidents, tracked separately from the incidents it explains.
Incidents link to a problem record, which accumulates them. The known workaround lives there, so agents apply it consistently while the underlying fix is pursued as a task in Loop.
A fault reported roughly monthly for a year shows as one problem with twelve incidents and their total handling time — which is the business case, and it is arithmetic.
It will not fix anything. It makes the recurrence and its cost visible and gives the fix somewhere to live; the engineering is still engineering.
Its incidents, the workaround, the Loop task pursuing the fix, and the change that eventually resolves it.
Yes — known error with a workaround is a legitimate state.
Only those still open, and each is notified.
They see their own incident's status, not the problem record.
Fourteen days, every module, no card. Or half an hour with someone who will run it on your own records and tell you where it does not help.
