Nonconformance Cost at 43% share reaching full mrb: a worked example in space payload & avionics manufacturing

Suppose share reaching full mrb falls to 43%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimates the cost of processing and dispositioning nonconformances across a flight hardware build.

The inputs for this scenario

  • Nonconformance Reports Raised: 35 NCRs (held at the documented default)
  • Disposition Cost per NCR: 1,800 $/NCR (held at the documented default)
  • Share Reaching Full MRB: 43 % (the input this scenario stresses; the baseline uses 60)
  • Quality System Overhead: 6,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total cost = NCRs raised x disposition cost per NCR x share reaching MRB + quality overhead.
  • Total nonconformance cost works out to 33,090 $ at these inputs, and this is the headline figure for the scenario.
  • Nonconformance cost per unit works out to 945 $ / piece at these inputs.
  • Variable nonconformance cost works out to 27,090 $ at these inputs.
  • Fixed nonconformance cost adder works out to 6,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share reaching full mrb sits at 60% and the headline result is 43,800 $, this scenario comes in 24.45% below the baseline at 33,090 $.
  • It computes total nonconformance cost as NCRs raised times disposition cost per NCR times the share that reaches full MRB, plus fixed quality-system overhead, and divides by NCR count for a per-NCR figure. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Total nonconformance cost: 33,090 $ (headline result)
  • Nonconformance cost per unit: 945 $ / piece
  • Variable nonconformance cost: 27,090 $
  • Fixed nonconformance cost adder: 6,000 $
