Cleanroom & Contamination Control worked example

Cleanroom Compliance Score with compliance impact severity score of 20 score: a worked example

This scenario runs the cleanroom compliance score calculation on the strong side: compliance impact severity score of 20 score, with every other input held at its documented default. a team needs to prioritize compliance remediation before product release, customer audits, or regulatory inspection for a cleanroom compliance review

The inputs for this scenario

  • Compliance impact severity score: 20 score (raised for this scenario; the documented default is 8)
  • Compliance gap occurrence score: 3 score (unchanged)
  • Control detection weakness score: 5 score (unchanged)

Working through the calculation

  • Applying the documented formula (Cleanroom Compliance Score risk score = compliance impact severity score × compliance gap occurrence score × control detection weakness score) to the inputs above produces each figure below.
  • At this operating point the engine returns 10.3 score for cleanroom compliance score risk score, the number this scenario is built around.
  • At this operating point the engine returns 20 score for compliance impact severity score.
  • At this operating point the engine returns 3 score for compliance gap occurrence score.
  • At this operating point the engine returns 5 score for control detection weakness score.

How this compares with the baseline

  • Against the tool's baseline example, where compliance impact severity score sits at 8 score and the headline result is 5.5 score, this scenario comes in 87.27% above the baseline at 10.3 score.
  • Use it when triaging environmental monitoring excursions, gowning or behavior audit findings, particle count trends, or any cleanroom deviation that needs prioritization across an FMEA or risk register. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
