Cleanroom Audit Readiness with audit finding severity score of 18 score: a worked example

Push audit finding severity score up to 18 score and the picture changes. This example computes every intermediate figure at that operating point. a team needs to prioritize audit preparation work before GMP, ISO, customer, or internal inspections for a cleanroom audit readiness review

The inputs for this scenario

  • Audit finding severity score: 18 score (raised for this scenario; the documented default is 7)
  • Readiness gap occurrence score: 4 score (unchanged)
  • Documentation detection weakness score: 5 score (unchanged)

Working through the calculation

  • Applying the documented formula (Cleanroom Audit Readiness risk score = audit finding severity score × readiness gap occurrence score × documentation detection weakness score) to the inputs above produces each figure below.
  • At this operating point the engine returns 9.85 score for cleanroom audit readiness risk score, the number this scenario is built around.
  • At this operating point the engine returns 18 score for audit finding severity score.
  • At this operating point the engine returns 4 score for readiness gap occurrence score.
  • At this operating point the engine returns 5 score for documentation detection weakness score.

How this compares with the baseline

  • Against the tool's baseline example, where audit finding severity score sits at 7 score and the headline result is 5.45 score, this scenario comes in 80.73% above the baseline at 9.85 score.
  • It computes a single audit-readiness risk score by multiplying the severity of a potential finding, how often the underlying readiness gap occurs, and how poorly current documentation would detect it. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
