SituationUnderJust RightOver
An open commitment from MondayStarts new work and leaves the Monday item sitting. The person waiting finds out only when they ask.Finishes it or names a new date before picking up the next thing. Says what will wait and who needs to know.Guards every leftover thread until each one is perfect. Time-sensitive work waits while old items get extra polish.
The first approach fails midweekStops and waits for a cleaner plan or a new owner. The original date stays on the calendar.Tries another path the same day and tells the people waiting what changed. Keeps the outcome and drops the method that failed.Spends the rest of the week forcing the first approach. Neighboring work sits, and the date still moves.
Calling a piece of work doneMarks it done while the handoff, check, or last user step is still open. The next person finds the holes.Confirms someone can actually use it, then stops. Leaves small nits only when they do not block use, and writes them down.Refuses to close until every nit is gone. People who needed it wait while it keeps getting touched.
Two deadlines in the same weekWorks whichever is louder and lets the other slip with no notice.Chooses the one that matters more, tells the other stakeholder what will move, and finishes the first one so it can be used.Promises both will land and splits the week so thin that neither result is usable.
A new request arrives midweekAdds it without moving anything already promised. Both pieces start to slip.Weighs it against this week's commitments. Takes it only if something else is deferred out loud, or if the new work is truly small.Protects the original list so tightly that a small, time-sensitive ask waits a week for no real reason.
Giving status when the work is behindStays quiet or still says on track. The slip appears only when the date arrives.Says what is late, what will still land this week, and what they need. Gives others time to react.Sends frequent updates that restate the same risk. People spend the week reading status instead of unblocking the work.
Inputs are still incompleteWaits for every input to be clean before starting. The date does not move, and the week goes by.Starts with what is in hand, marks the assumptions, and adjusts when the rest arrives.Builds a full answer on guesses so they can say they started. The real inputs arrive and the week is spent redoing it.
After a date is missedDoes not reset the plan. The miss goes unexplained, and the next date is just as soft.Says what slipped, why, and the new date they will actually hit. Cuts scope if that is what makes the new date real.Names a tight catch-up date to repair the miss. The following week starts already behind.
