How should I brief a day-of helper who has not been part of the planning?
Quick answer
Give your helper one concise, easy-to-find briefing sheet that explains the event, their responsibilities, the schedule, and who to contact. Mark which decisions they can make on their own and which require approval. Include practical details they need to act, such as locations and setup priorities, and leave out background that will not help them on the day. Confirm they know where to find the sheet and how to reach you.
The question, the details, the next step.
A practical checklist
Put the helper’s goal and shift times at the top.
List tasks in priority order, with locations and clear completion cues.
Separate fixed times from flexible targets and state what takes priority if delayed.
Name decisions the helper can make, those needing approval, and what to do if nobody responds.
Check that contact methods, supply locations, and unresolved details are clear before sharing.
A few more useful answers
Should I send the briefing sheet in advance or give it to the helper on the day?
Share it in advance when practical so the helper can ask questions. Also make sure they can find the current version on the day, whether that is a printed copy or a file you have agreed to use.
What if some event details are still undecided?
Mark them as [confirm] and say who will confirm them and by when. Do not write an unconfirmed guess as if it were settled.
How can I tell whether the brief is clear enough?
Ask the helper to explain their first task, one priority if timing slips, and what they should do before making a decision that needs approval. Clarify any answer that differs from your intention.
