QMS, CAPA & Quality System Management worked example

CAPA Effectiveness Rate at 99% target recurrence ceiling: a worked example

Push target recurrence ceiling up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when capa effectiveness rate in qms, capa and quality system management needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Recurring nonconformances after CAPA closure: 8 count (unchanged)
  • Total CAPAs closed in the period: 250 count (unchanged)
  • Target recurrence ceiling: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Capa effectiveness rate = capa effectiveness rate count ÷ total capa effectiveness rate population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for capa effectiveness rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for capa effectiveness rate gap to target.
  • At this operating point the engine returns 8 count for capa effectiveness rate count.
  • At this operating point the engine returns 250 count for total capa effectiveness rate population.

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 %.
  • It computes the recurrence percentage after CAPA closure and the gap between that rate and your target ceiling. 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.

Results at a glance

  • Capa effectiveness rate: 3.2 % (headline result)
  • Capa effectiveness rate gap to target: 95.8 points
  • Capa effectiveness rate count: 8 count
  • Total capa effectiveness rate population: 250 count

Run it with your numbers

  • Every input above is editable in the live CAPA Effectiveness Rate calculator, which recalculates instantly and can be shared with the inputs intact.
