Which assumption is carrying your conclusion?
Every plan relies on something being true. A weekend event might assume that guests are free, the venue is accessible and the equipment works. Listing these assumptions exposes where the plan is fragile. The most important assumption is often the one that would change the decision if it proved false.

Make the hidden conditions visible
Suppose a club plans an outdoor evening screening. The equipment list looks complete, but the plan quietly assumes there is a suitable power supply at the location.
That assumption matters more than the choice of poster colour. If it fails, the screening may not happen.
An assumption audit makes these dependencies explicit:
- What must be true for this plan to work?
- Which conditions have actually been checked?
- Which unchecked condition could cause the largest change?
The purpose is not to list every imaginable uncertainty. It is to identify the few beliefs carrying the decision. Checking the power connection directly is more useful than polishing a schedule built around equipment that may never turn on.
