QMS, CAPA & Quality System Management worked example

Risk Register Coverage with severity of harm if the risk occurs of 3 score: a worked example

This worked example runs the risk register coverage numbers for a tougher week than the baseline: severity of harm if the risk occurs of 3 score instead of the typical 6 score. Estimate risk register coverage for qms, capa and quality system management using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.

The inputs for this scenario

  • Severity of harm if the risk occurs: 3 score (the input this scenario stresses; the baseline uses 6)
  • Likelihood the risk occurs (occurrence): 4 score (held at the documented default)
  • Chance controls fail to detect it (detection): 3 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Risk register coverage risk score = risk register coverage severity score × risk register coverage occurrence score × risk register coverage detection score.
  • Risk register coverage risk score works out to 3.35 score at these inputs, and this is the headline figure for the scenario.
  • Risk register coverage severity score works out to 3 score at these inputs.
  • Risk register coverage occurrence score works out to 4 score at these inputs.
  • Risk register coverage detection score works out to 3 score at these inputs.

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 26.37% below the baseline at 3.35 score.
  • Use it when triaging or reviewing a quality risk register, or during an FMEA, to prioritize which risks need action. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Risk register coverage risk score: 3.35 score (headline result)
