Model Validation Workload at 40% retest and approval allowance: a worked example

This scenario runs the model validation workload calculation on the strong side: 40% retest and approval allowance, with every other input held at its documented default. Use it when quality, data science, or model risk teams need to plan validation work before deployment or model update approval.

The inputs for this scenario

  • Validation checks or test samples to review: 420 checks (unchanged)
  • Validation checks reviewed per minute: 5 checks / min (unchanged)
  • Retest and approval allowance: 40 % (raised for this scenario; the documented default is 35)

Working through the calculation

  • Applying the documented formula (Base model validation time = validation checks or samples รท validation review rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 118 min for required model validation time, the number this scenario is built around.
  • At this operating point the engine returns 84 min for base model validation time.
  • At this operating point the engine returns 40 % for retest and approval allowance.
  • At this operating point the engine returns 5 pieces / min for validation review rate.

How this compares with the baseline

  • Against the tool's baseline example, where retest and approval allowance sits at 35% and the headline result is 113 min, this scenario comes in 3.7% above the baseline at 118 min.
  • Use it when scheduling a model release, planning validation staffing, or estimating how long a retraining cycle's sign-off will take. 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 model validation time: 118 min (headline result)
  • Base model validation time: 84 min
  • Retest and approval allowance: 40 %
  • Validation review rate: 5 pieces / min

Run it with your numbers

  • Every input above is editable in the live Model Validation Workload calculator, which recalculates instantly and can be shared with the inputs intact.
