Supplier Quality, Development & Audits worked example

Supplier Escape Cost at 50% containment effectiveness: a worked example in supplier quality, development & audits

This worked example runs the supplier escape cost numbers for a tougher week than the baseline: 50% containment effectiveness instead of the typical 70%. Estimates the financial impact of nonconforming supplier parts that escape detection and reach your production line.

The inputs for this scenario

  • Escaped defective parts: 500 parts (held at the documented default)
  • Cost per escape event: 45 $/part (held at the documented default)
  • Containment effectiveness: 50 % (the input this scenario stresses; the baseline uses 70)
  • Investigation and 8D adder: 3,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total escape cost = escaped parts x cost per escape x containment% + investigation adder.
  • Total supplier escape cost works out to 14,750 $ at these inputs, and this is the headline figure for the scenario.
  • Supplier escape cost per unit works out to 29.5 $ / piece at these inputs.
  • Variable supplier escape cost works out to 11,250 $ at these inputs.
  • Fixed supplier escape cost adder works out to 3,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where containment effectiveness sits at 70% and the headline result is 19,250 $, this scenario comes in 23.38% below the baseline at 14,750 $.
  • Use it when a supplier nonconformance reaches your process or customer and you need to size the chargeback, containment budget, or supplier scorecard cost-of-poor-quality entry. 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
