Audited planning profile
This lean ten-year profile applies a 0.75× editable baseline across 120 model periods to the fundraiser buffer model.
Use the buffered result for planning and the unbuffered result as the transparent baseline. Treat the lean scale as a lower-bound plan and test whether essential fixed costs still fit. Use a wide uncertainty range; small recurring assumption errors compound substantially over ten years.
Venue rules, taxes, permits, cancellation terms, accessibility, weather and vendor availability are not inferred.
Confirm headcount, written vendor quotes, venue conditions and a cancellation contingency.
