Under, just right, over.

SituationUnderJust RightOver
Covering work before time offLeaves without a handoff. Open threads sit until they get back.Writes what is in flight, who can decide what, and the one case worth a ping. The team can move, and they actually rest.Stays in the threads all week and redoes the backup's calls. The backup never owns it, and they return already tired.
Closing the ticketMarks it done when the code is merged. Does not check whether the person who needed it can finish the job.Confirms the outcome landed. If something remains, they name an owner for it before they close.Leaves it open to chase extras that were never in the ask. Work behind it waits.
A workaround that will stickShips the patch and walks away. The next person hits the same hole with no note.Ships the patch so the week is unblocked, then either schedules the real fix or writes why the patch is the answer.Holds the release for a full rewrite. People wait on a problem that already had a safe patch.
A stalled decision threadWatches the thread and adds nothing. The week slips while people wait for a more senior voice.Posts a recommendation, who is hurt if they wait, and a time they will proceed if no one objects.Calls it alone on something that binds other teams. The next days are spent undoing it.
Leftovers after a launchTreats launch day as the finish line. Docs, known bugs, and follow-ups have no name on them.Before the team scatters, they list what is left, what can wait, and who takes each piece.Will not call it launched until every leftover is gone. The next start date moves.
Two teams started the same workNotices the overlap and keeps building their version. Two answers land and one gets thrown out.Stops, compares scope, and picks which team finishes. The other team's time goes back to their plan.Takes both piles and rebuilds a combined version so they can be the owner. Both teams lose the week they already spent.
Changing a shared interfaceChanges it for their case and ships. Other teams find out when their work breaks.Names who consumes it, gives them a window, and keeps a path for old callers through this week.Waits until every consumer has moved, including teams not using the field. A small fix sits while their own users stay blocked.
A promise someone else madeTells the customer it is not their promise. The customer is left with no next step.Owns the next conversation. They confirm what was promised, what can actually ship, and who will say so.Honors a promise the team cannot keep so they look like the owner. Planned work for the week gets dropped.
