QMS, CAPA & Quality System Management worked example

Deviation Closure Time at 7.2% investigation, review, and sign-off allowance: a worked example

This worked example runs the deviation closure time numbers for a tougher week than the baseline: 7.2% investigation, review, and sign-off allowance instead of the typical 10%. Estimate deviation closure time for qms, capa and quality system management using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.

The inputs for this scenario

  • Open deviations awaiting closure: 120 units (held at the documented default)
  • Deviation disposition rate per reviewer: 12 units / min (held at the documented default)
  • Investigation, review, and sign-off allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base deviation closure time = deviation closure time workload รท deviation closure time completion rate.
  • Required deviation closure time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base deviation closure time works out to 10 hr at these inputs.
  • Deviation closure time allowance applied works out to 7.2 % at these inputs.
  • Deviation closure time completion rate works out to 12 pieces / min at these inputs.

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 2.55% below the baseline at 10.72 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. 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

  • Required deviation closure time: 10.72 hr (headline result)
  • Base deviation closure time: 10 hr
  • Deviation closure time allowance applied: 7.2 %
  • Deviation closure time completion rate: 12 pieces / min

Run it with your numbers
