Residue Risk Score with residue impact score of 20 score: a worked example

This scenario runs the residue risk score calculation on the strong side: residue impact score of 20 score, with every other input held at its documented default. Use it when quality or process engineering teams need to prioritize oil, detergent, solvent, or particulate residue risks.

The inputs for this scenario

  • Residue impact score: 20 score (raised for this scenario; the documented default is 8)
  • Residue occurrence score: 5 score (unchanged)
  • Residue detection difficulty score: 4 score (unchanged)

Working through the calculation

  • Applying the documented formula (Residue risk score = residue impact score × residue occurrence score × residue detection difficulty score) to the inputs above produces each figure below.
  • At this operating point the engine returns 10.75 score for residue risk score, the number this scenario is built around.
  • At this operating point the engine returns 20 score for residue impact score.
  • At this operating point the engine returns 5 score for residue occurrence score.
  • At this operating point the engine returns 4 score for residue detection difficulty score.

How this compares with the baseline

  • Against the tool's baseline example, where residue impact score sits at 8 score and the headline result is 5.95 score, this scenario comes in 80.67% above the baseline at 10.75 score.
  • Use it during a cleaning-process FMEA or audit to prioritize which residue risks to mitigate first. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Residue risk score: 10.75 score (headline result)
