Cleaning Validation Workload at 46% protocol, deviation, and approval allowance: a worked example

Push protocol, deviation, and approval allowance up to 46% and the picture changes. This example computes every intermediate figure at that operating point. Use it when quality, process engineering, or manufacturing teams need to plan validation effort for a new or changed cleaning process.

The inputs for this scenario

  • Cleaning validation samples or records to review: 180 records (unchanged)
  • Validation review completion rate: 0.55 records / min (unchanged)
  • Protocol, deviation, and approval allowance: 46 % (raised for this scenario; the documented default is 40)

Working through the calculation

  • Applying the documented formula (Base cleaning validation time = cleaning validation samples or records รท validation review completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 478 min for required cleaning validation time, the number this scenario is built around.
  • At this operating point the engine returns 327 min for base cleaning validation time.
  • At this operating point the engine returns 46 % for protocol, deviation, and approval allowance.
  • At this operating point the engine returns 0.55 pieces / min for validation review completion rate.

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 4.29% above the baseline at 478 min.
  • It computes the total review minutes needed to clear a set of cleaning validation records, including a percentage allowance for protocol handling, deviations, and approvals. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required cleaning validation time: 478 min (headline result)
  • Base cleaning validation time: 327 min
  • Protocol, deviation, and approval allowance: 46 %
  • Validation review completion rate: 0.55 pieces / min
