QMS, CAPA & Quality System Management worked example

Risk Register Coverage with severity of harm if the risk occurs of 15 score: a worked example

Push severity of harm if the risk occurs up to 15 score and the picture changes. This example computes every intermediate figure at that operating point. Use it when risk register coverage in qms, capa and quality system management needs a defensible ranking against other qms, capa and quality system management risks for the next review.

The inputs for this scenario

  • Severity of harm if the risk occurs: 15 score (raised for this scenario; the documented default is 6)
  • Likelihood the risk occurs (occurrence): 4 score (unchanged)
  • Chance controls fail to detect it (detection): 3 score (unchanged)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where severity of harm if the risk occurs 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.
  • It multiplies severity, occurrence, and detection ratings into a single risk priority number for ranking register entries. 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.
