QMS, CAPA & Quality System Management worked example

Deviation Closure Time at 12% investigation, review, and sign-off allowance: a worked example

This scenario runs the deviation closure time calculation on the strong side: 12% investigation, review, and sign-off allowance, with every other input held at its documented default. Use it when deviation closure time in qms, capa and quality system management is being added to next week's schedule and you need an honest hours estimate.

The inputs for this scenario

  • Open deviations awaiting closure: 120 units (unchanged)
  • Deviation disposition rate per reviewer: 12 units / min (unchanged)
  • Investigation, review, and sign-off allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where investigation, review, and sign-off allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • Use it when planning quality-review capacity, forecasting deviation backlog burn-down before an audit, or committing to a closure timeline for aging records. 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

  • Required deviation closure time: 11.2 hr (headline result)
  • Base deviation closure time: 10 hr
  • Deviation closure time allowance applied: 12 %
  • Deviation closure time completion rate: 12 pieces / min

Run it with your numbers

  • Every input above is editable in the live Deviation Closure Time calculator, which recalculates instantly and can be shared with the inputs intact.
