Deviation Cost at 92% deviation scope included: a worked example

Push deviation scope included up to 92% and the picture changes. This example computes every intermediate figure at that operating point. Use it when GMP, QA, QC, validation, manufacturing, or operations teams need a quick planning estimate to prioritize deviation reduction, size investigation budgets, and quantify quality event exposure.

The inputs for this scenario

  • GMP deviation count: 100 deviations (unchanged)
  • Average investigation cost: 45 $ / deviation (unchanged)
  • Deviation scope included: 92 % (raised for this scenario; the documented default is 80)
  • Fixed remediation or CAPA cost: 250 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable GMP deviation cost = GMP deviation count × Average investigation cost × Deviation scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,390 $ for total gmp deviation cost, the number this scenario is built around.
  • At this operating point the engine returns 43.9 $ / piece for deviation cost per event.
  • At this operating point the engine returns 4,140 $ for allocated investigation cost.
  • At this operating point the engine returns 250 $ for fixed remediation cost.

How this compares with the baseline

  • Against the tool's baseline example, where deviation scope included sits at 80% and the headline result is 3,850 $, this scenario comes in 14.03% above the baseline at 4,390 $.
  • It computes the total cost of GMP deviations by combining scope-adjusted investigation cost with a fixed remediation or CAPA charge, then divides to a per-event figure. 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.
