“Where do I start?”
Getting started with quantitative risk assessment is easier than you might think.
If you’re calling the shots at your organization, drop ordinal scoring (i.e. using 1, 2, 3 or low, moderate, high) entirely and replace it with dollar amount ranges for impacts and frequency ranges for probabilities. For example:
If you’re not calling the shots at your organization, and you can’t convince your stakeholders to go quantitative, ask them if you can run a pilot quantitative risk assessment alongside your next assessment target.
Collect ordinal scores from your estimators like you normally do, but also ask them to provide range estimates.
Add a new column, or columns, next to your risk scores to collect the range estimates, like this:
“Ok got it, but how can I try it out?”
This is the process at a high level, and you can start doing this today! Try out this starter quantitative risk assessment spreadsheet we developed.
