Name the boundary before you join the rescue.

Imagine a small touring theater two days before opening night. The stage manager becomes ill, the company has arrived in an unfamiliar town, and nobody has confirmed how the scenery will move through the loading door. You are asked to step in because you have run shows in that venue before.

Rescue work creates an unusual risk. Everyone is relieved that you arrived, so nobody stops to define what your arrival means. You think you are solving the load-in. The director thinks you now own backstage operations. The venue manager thinks you are the company's decision-maker. If the opening goes badly, the newest person with the vaguest role becomes an easy place to put the whole story.

The solution is not to refuse every rescue. It is to close the open seat before the work begins.

Amy Edmondson's research on teams shows how strongly people need psychological safety to report errors and learn from them. When a group feels threatened, it becomes easier to protect yourself by locating one person who caused the problem. A newcomer without a written boundary is especially exposed because nobody has to contradict a clear agreement before widening that person's responsibility.

The planning fallacy adds pressure. Daniel Kahneman and Amos Tversky described our habit of imagining a plan from the inside, with each step going well. A stressed theater company may sincerely believe that the remaining work is small. That optimism makes it even more important to say what you will deliver instead of letting everyone assume the whole opening is now covered.

Write three lines where the relevant people can see them. What you are doing: planning the load-in, assigning the moving crew, and running a safety check. What you are not doing: calling lighting cues, repairing costumes, or approving changes to the set. What you will hand over: a marked route, a crew list, and a completed safety walk before rehearsal.

This resembles commander's intent, an approach Stephen Bungay describes in The Art of Action. State the result that matters, then make the boundaries clear enough that people can adapt inside them. You do not need detailed permission for every choice about the load-in because everyone knows the outcome you own. The lighting operator can improvise inside a different boundary without assuming you have taken it over.

The line about what you are not doing matters most. People remember promises. They rarely remember assumptions that were never corrected. Naming the unowned work also helps the original team. It tells the director that someone still has to call the show and tells the wardrobe lead that costume repairs did not disappear when help arrived.

Your boundary can move. You may finish the load-in early and agree to organize the prop table. If it moves, say so in the same visible place: I can add the prop check, while cue calling remains with the assistant director. Extra help should become a new agreement, not a silent expansion.

Do not confuse a boundary with coldness. You can be generous, stay late, and care deeply about opening night. The boundary simply makes generosity legible. It lets everyone know which risks are covered and which still need an owner.

One thing to try today: before joining any troubled effort, find the written description of your role. If there is none, write three short lines: doing, not doing, handing over. Put them in the place where the people relying on you will see them. Then start the work.

That is the lesson. A rescue needs more than willing hands. Name the result, name the boundary, and make every expansion explicit so help does not quietly become ownership of the whole wreck.
