Single-Use Bioprocess Assemblies worked example

Validation Cost at 110% billable validation share: a worked example in single-use bioprocess assemblies

Push billable validation share up to 110% and the picture changes. This example computes every intermediate figure at that operating point. A validation lead pricing the extractables, integrity, and sterility test program for a new single-use assembly design.

The inputs for this scenario

  • Validation Test Runs: 24 runs (unchanged)
  • Cost per Validation Run: 850 $/run (unchanged)
  • Billable Validation Share: 110 % (raised for this scenario; the documented default is 100)
  • Protocol & Report Setup: 4,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total validation cost = validation runs x cost per run x billable share + protocol & report setup) to the inputs above produces each figure below.
  • At this operating point the engine returns 26,940 $ for total validation cost, the number this scenario is built around.
  • At this operating point the engine returns 1,123 $ / piece for validation cost per unit.
  • At this operating point the engine returns 22,440 $ for variable validation cost.
  • At this operating point the engine returns 4,500 $ for fixed validation cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where billable validation share sits at 100% and the headline result is 24,900 $, this scenario comes in 8.19% above the baseline at 26,940 $.
  • It computes the total and per-run validation cost from test-run volume, cost per run, the billable share of run cost, and a fixed protocol and report setup 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.

Results at a glance

  • Total validation cost: 26,940 $ (headline result)
  • Validation cost per unit: 1,123 $ / piece
  • Variable validation cost: 22,440 $
  • Fixed validation cost adder: 4,500 $
