Fund the safe project or the risky one?

Innovation budgets default to the safe bet because a 75% failure rate sounds disqualifying. But when a cheap prototype stage lets you kill the project before the expensive launch, the risky project can quietly dominate the incremental option. This tree makes that flip visible in one Run.

After you install, this is the model to open.

Fund the Safe Project or the Risky One?

  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

Click Run and the rollback picks the best action at every gate, then rolls the value back to the root.

Risky project expected value
$1.0M with the prototype kill option
Safe refresh expected value
$625K 50/50 between $850K and $400K
Risky project if launch is forced
$175K no stage gate, it loses to the refresh
What the kill option is worth
$825K $1.0M minus $175K

The risky project rolls back to a $1.0M expected value, 1.6 times the safe refresh at $625K, even though it disappoints 75% of the time. The entire edge comes from the stage gate: forced to launch either way, the risky project is worth only $175K and the safe project wins. The right to spend $500K, look at the prototype, and walk away is worth $825K by itself.

The model

Three ways to spend one product budget, with every leaf shown net of the costs on its path.

Refresh, strong adoption (50%)+$850K net
Refresh, soft adoption (50%)+$400K net
Prototype cost, risky project$500K
Breakthrough odds25%
Breakthrough launch payoff+$5.5M net of a $2M launch
Modest result, launch anyway-$1.6M net
Modest result, kill it-$500K, prototype cost only

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.
