This Google Docs template helps event organizers decide whether a new event is worth running before significant money is committed. It moves through eight pages: a concept with three tests, the demand evidence, the venue plan, the budget, a pilot variance check, a verdict with sign-off and next steps, and a guide page. Each heading states its point, so a sponsor can read the decision first and the workings after.

Every figure is sample data for Amberley Engineering, a fictional firm planning Foundry Days, a two-day engineering show with 80 stands. The sample reaches a conditional go: break-even at 52 paid stands, which is 65 percent of capacity, with a 10 percent contingency. Replace the interview counts, pilot numbers, venue quotes and sign-off names with your own, then check that the verdict still follows from the numbers.
