Contamination Risk Score with contamination severity score of 15 score: a worked example in pharmaceutical, biotech & gmp manufacturing

This scenario runs the contamination risk score calculation on the strong side: contamination severity score of 15 score, with every other input held at its documented default. Use it when GMP, QA, QC, validation, manufacturing, or operations teams need a quick planning estimate to prioritize contamination control actions, environmental monitoring focus, and aseptic process improvements.

The inputs for this scenario

  • Contamination severity score: 15 score (raised for this scenario; the documented default is 6)
  • Occurrence likelihood score: 4 score (unchanged)
  • Detection weakness score: 3 score (unchanged)

Working through the calculation

  • Applying the documented formula (Risk score = severity score × 0.40 + occurrence score × 0.35 + detection weakness score × 0.25) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.15 score for contamination risk score, the number this scenario is built around.
  • At this operating point the engine returns 15 score for severity score.
  • At this operating point the engine returns 4 score for occurrence score.
  • At this operating point the engine returns 3 score for detection weakness score.

How this compares with the baseline

  • Against the tool's baseline example, where contamination severity score sits at 6 score and the headline result is 4.55 score, this scenario comes in 79.12% above the baseline at 8.15 score.
  • Use it during contamination control strategy reviews, aseptic process risk assessments, or when prioritizing CAPA and monitoring investments across multiple failure modes. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
