The feature doesn't work.
It's not critical, but there's a rush to fix it.
Two people are pulled off something else to deal with this.
The code is sloppy, but the original problem is gone so the fix is deployed.
A post-mortem is scheduled so 9 people can review what happened.
New QA procedures are applied to every project moving forward so it doesn't happen again.
The sloppy code that fixed the issue is never cleaned up.
So... Where's the bug?
