How to make hard decisions under uncertainty

In business, decisions often have to be made without precise numbers or time for complex models. But the risk still needs to be assessed. I share a method I have used for years — it structures thinking and removes the fear of error.

The three-scenario method

The method requires no calculations — it helps put your thinking in order. Describe three ways events could unfold.

  • Worst. Imagine everything went wrong. What losses would you bear — money, time, reputation, partner relationships? Do not assess probability, just honestly describe the "bottom".
  • Most likely. The outcome that, by your sense of it, will most probably occur. What results would it lead to?
  • Best. What happens if everything goes perfectly. This is what you will aim for.

Two questions that give the answer

Now the key part. Take the most likely scenario and ask:

  1. Does it lead to my goal? If the likely outcome does not move you toward what you are starting the project for, you should not enter — even if there are no fears.
  2. If the answer is "yes", move to the worst scenario: can I survive it? The business will not collapse, I will not lose everything? If "yes" here too — the decision can be made: you can withstand the worst, and the likely outcome leads to the goal.
Three scenarios and two questions give clarity in minutes — where there is neither data nor time for a full analysis.

I used this method back at Beeline when assessing the risks of IT projects and startups: the scale did not always allow a deep analysis, yet the go/no-go decision had to be made fast.

FAQ

When is the three-scenario method appropriate?

When you need a quick decision under uncertainty, with no precise data and no time for complex models. For large, costly decisions it is complemented by quantitative risk assessment.

How is this different from a full risk analysis?

It is an express tool for speed and clarity. It does not replace a detailed analysis but guards against the main mistake — entering a project that even in the likely scenario does not lead to the goal, or in the worst case is fatal.
