Single-Use Bioprocess Assemblies worked example

Validation Cost at 72% billable validation share: a worked example in single-use bioprocess assemblies

This worked example runs the validation cost numbers for a tougher week than the baseline: 72% billable validation share instead of the typical 100%. Estimate validation cost for single-use bioprocess assemblies from test run count, per-run cost, billable share, and protocol setup.

The inputs for this scenario

  • Validation Test Runs: 24 runs (held at the documented default)
  • Cost per Validation Run: 850 $/run (held at the documented default)
  • Billable Validation Share: 72 % (the input this scenario stresses; the baseline uses 100)
  • Protocol & Report Setup: 4,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total validation cost = validation runs x cost per run x billable share + protocol & report setup.
  • Total validation cost works out to 19,188 $ at these inputs, and this is the headline figure for the scenario.
  • Validation cost per unit works out to 800 $ / piece at these inputs.
  • Variable validation cost works out to 14,688 $ at these inputs.
  • Fixed validation cost adder works out to 4,500 $ at these inputs.

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 22.94% below the baseline at 19,188 $.
  • Use it when quoting the validation portion of a new single-use assembly program or budgeting a material, supplier or design change. 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

  • Total validation cost: 19,188 $ (headline result)
  • Validation cost per unit: 800 $ / piece
  • Variable validation cost: 14,688 $
  • Fixed validation cost adder: 4,500 $
