Cleaning Validation Workload at 29% protocol, deviation, and approval allowance: a worked example

This worked example runs the cleaning validation workload numbers for a tougher week than the baseline: 29% protocol, deviation, and approval allowance instead of the typical 40%. Estimate workload for validating a cleaning process using validation samples, review rate, and protocol allowance.

The inputs for this scenario

  • Cleaning validation samples or records to review: 180 records (held at the documented default)
  • Validation review completion rate: 0.55 records / min (held at the documented default)
  • Protocol, deviation, and approval allowance: 29 % (the input this scenario stresses; the baseline uses 40)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base cleaning validation time = cleaning validation samples or records รท validation review completion rate.
  • Required cleaning validation time works out to 422 min at these inputs, and this is the headline figure for the scenario.
  • Base cleaning validation time works out to 327 min at these inputs.
  • Protocol, deviation, and approval allowance works out to 29 % at these inputs.
  • Validation review completion rate works out to 0.55 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where protocol, deviation, and approval allowance sits at 40% and the headline result is 458 min, this scenario comes in 7.86% below the baseline at 422 min.
  • Use it when scheduling a validation review window, sizing QA staffing for a campaign, or quoting a turnaround time to production after a cleaning study. 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 cleaning validation time: 422 min (headline result)
  • Base cleaning validation time: 327 min
  • Protocol, deviation, and approval allowance: 29 %
  • Validation review completion rate: 0.55 pieces / min

Run it with your numbers

  • To rerun this with your own numbers, open the live Cleaning Validation Workload calculator, set protocol, deviation, and approval allowance to your actual value, and adjust the remaining inputs to match your operation.
