Batch Record Review Cost at 81% review completion rate: a worked example

Push review completion rate up to 81% and the picture changes. This example computes every intermediate figure at that operating point. Use this when budgeting QA headcount, justifying electronic batch record investments, or estimating the cost impact of increasing lot frequency.

The inputs for this scenario

  • Batch records to review: 20 records (unchanged)
  • QA reviewer hourly rate: 85 $ / hr (unchanged)
  • Review completion rate: 81 % (raised for this scenario; the documented default is 70)
  • Fixed review infrastructure cost: 1,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable batch record review cost = batch records to review × QA reviewer hourly rate × review completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,877 $ for total batch record review cost, the number this scenario is built around.
  • At this operating point the engine returns 144 $ / piece for average review cost per record.
  • At this operating point the engine returns 1,377 $ for variable reviewer labor cost.
  • At this operating point the engine returns 1,500 $ for fixed review infrastructure cost.

How this compares with the baseline

  • Against the tool's baseline example, where review completion rate sits at 70% and the headline result is 2,690 $, this scenario comes in 6.95% above the baseline at 2,877 $.
  • It multiplies the number of records, the reviewer rate, and a completion-rate factor to get variable review labor, then adds fixed infrastructure cost. 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.
