QMS, CAPA & Quality System Management worked example

Corrective Action Cycle Time at 12% investigation & approval allowance: a worked example

What does the result look like when investigation & approval allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when corrective action cycle time in qms, capa and quality system management needs a defensible run time before a quote goes out.

The inputs for this scenario

  • CAPA Actions in the Queue: 120 actions (unchanged)
  • CAPA Closure Rate: 12 actions / min (unchanged)
  • Investigation & Approval Allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base corrective action cycle time = corrective action cycle time workload รท corrective action cycle time completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required corrective action cycle time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base corrective action cycle time.
  • At this operating point the engine returns 12 % for corrective action cycle time allowance applied.
  • At this operating point the engine returns 12 pieces / min for corrective action cycle time completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where investigation & approval allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • A figure at this level is achievable when investigation & approval allowance is genuinely sustained, not just peaked for a shift. It assumes a uniform closure rate; a single CAPA stuck awaiting cross-functional root-cause or external verification can blow past the average and should be tracked individually.

Results at a glance

  • Required corrective action cycle time: 11.2 hr (headline result)
  • Base corrective action cycle time: 10 hr
  • Corrective action cycle time allowance applied: 12 %
  • Corrective action cycle time completion rate: 12 pieces / min
