QMS, CAPA & Quality System Management worked example

Nonconformance Closure Rate at 99% target closure rate: a worked example

This scenario runs the nonconformance closure rate calculation on the strong side: 99% target closure rate, with every other input held at its documented default. Use it when nonconformance closure 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

  • Nonconformances closed in period: 8 count (unchanged)
  • Nonconformances opened in period: 250 count (unchanged)
  • Target closure rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where target closure rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it in weekly or monthly quality reviews to gauge whether your team is keeping pace with incoming nonconformances and to prep for audits. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Nonconformance closure rate: 3.2 % (headline result)
  • Nonconformance closure rate gap to target: 95.8 points
  • Nonconformance closure rate count: 8 count
  • Total nonconformance closure rate population: 250 count
