Which event risks are worth paying to prevent?

A risk list becomes useful the moment every line carries a probability and an impact. Then you can ask the question that actually spends money well: does this mitigation remove more expected cost than it costs to buy?

Words on this sheet

  • Venue: The place an event is held. A venue line is what hiring it costs, usually a fixed amount whatever the turnout.

Marketing Intermediate Risk Register Pro engine

After you install, this is the model to open.

Event Risk Register

  1. In your spreadsheet, click the Sortia icon in the strip of icons down the right-hand edge. No strip? Click the arrow at the bottom-right to open it. You can also use Extensions, then Sortia, then Open Sortia.
  2. Click Start from a template and put that name in the search box.
  3. Pick the card with that name and click Load this template. It arrives on a new tab with real numbers already in it.

This one runs on a Pro engine, and every free install includes five full-quality runs on your own numbers, shared across all five Pro engines rather than five for each. After that, Pro is $199/year.

The answer

Exposure, and what mitigating buys:

Total exposure
$51K expected
After mitigations
$25.5K
Best buy
+$2.8K venue contract
Worst
−$1K weather plan

Expected exposure is $51,000, led by low ticket sales at $31,500, and the mitigations cut it to $25,500. The net-value column decides the budget: a written venue contract clears $2,800 for almost nothing, while the weather contingency spends $4,000 to remove $3,000 and loses money. Note the venue risk is only 5% likely but carries a $120,000 impact, which is why you read the impact column and not just the ranking.

Once it is in your sheet

  1. The model arrives with real numbers in it and runs as it stands, so you can press the button first and understand it second.
  2. Change the numbers to yours. The sheet marks which cells are inputs and which hold formulas, and most labels carry a note explaining the row.
  3. Press the run button at the bottom of the panel. It is labeled for the tool you are in, and the result lands on its own tab, with a written reading of it beside the figures.
