QMS, CAPA & Quality System Management worked example

CAPA Effectiveness Rate at 68% target recurrence ceiling: a worked example

This worked example runs the capa effectiveness rate numbers for a tougher week than the baseline: 68% target recurrence ceiling instead of the typical 95%. Estimate capa effectiveness rate for qms, capa and quality system management using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Recurring nonconformances after CAPA closure: 8 count (held at the documented default)
  • Total CAPAs closed in the period: 250 count (held at the documented default)
  • Target recurrence ceiling: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Capa effectiveness rate = capa effectiveness rate count ÷ total capa effectiveness rate population × 100.
  • Capa effectiveness rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Capa effectiveness rate gap to target works out to 64.8 points at these inputs.
  • Capa effectiveness rate count works out to 8 count at these inputs.
  • Total capa effectiveness rate population works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target recurrence ceiling sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it in monthly or quarterly management review and when preparing CAPA effectiveness evidence for an audit. 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

  • Capa effectiveness rate: 3.2 % (headline result)
  • Capa effectiveness rate gap to target: 64.8 points
  • Capa effectiveness rate count: 8 count
  • Total capa effectiveness rate population: 250 count
