BOM Routing Mismatch at 22% pairs with mismatches: a worked example

Suppose pairs with mismatches falls to 22%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the cost of reconciling BOM-to-routing mismatches that drive bad costing, shortages and scheduling errors.

The inputs for this scenario

  • BOM and routing pairs to check: 250 pairs (held at the documented default)
  • Reconciliation cost per pair: 60 $/pair (held at the documented default)
  • Pairs with mismatches: 22 % (the input this scenario stresses; the baseline uses 30)
  • Validation report build cost: 3,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total mismatch cost = pairs x reconciliation cost per pair x (mismatch % / 100) + validation report build.
  • Total bom routing mismatch cost works out to 6,800 $ at these inputs, and this is the headline figure for the scenario.
  • Bom routing mismatch cost per unit works out to 27.2 $ / piece at these inputs.
  • Variable bom routing mismatch cost works out to 3,300 $ at these inputs.
  • Fixed bom routing mismatch adder works out to 3,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where pairs with mismatches sits at 30% and the headline result is 8,000 $, this scenario comes in 15% below the baseline at 6,800 $.
  • It computes the total dollars to reconcile BOM-and-routing pairs given the share that are actually mismatched, plus a fixed validation report build, and the resulting cost per pair reviewed. 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 bom routing mismatch cost: 6,800 $ (headline result)
  • Bom routing mismatch cost per unit: 27.2 $ / piece
  • Variable bom routing mismatch cost: 3,300 $
  • Fixed bom routing mismatch adder: 3,500 $
