4. Implement a quantitative risk analysis

When qualitative analysis is not enough, or in certain complex cases when statistical and probabilistic data are available (e.g. analyzing the risk of a satellite colliding with orbiting waste to decide whether or not to modify the satellite's trajectory to avoid the object), it is then necessary to move on to quantitative analysis.

This involves a numerical analysis of the impact of identified risks.

This method requires time, costs, specialist skills and specific digital tools.

Cause-and-effect diagrams or Ishikawa diagrams are part of quantitative analysis methods, as are algorithms based on Monte-Carlo distributions.
