Port, Crane & Terminal Equipment worked example

Rework Cost at 54% confirmed nonconformance rate: a worked example in port, crane & terminal equipment

This worked example runs the rework cost numbers for a tougher week than the baseline: 54% confirmed nonconformance rate instead of the typical 75%. Estimate the cost to rework nonconforming port crane and terminal components from the count flagged, per-unit correction cost, and confirmed defect rate.

The inputs for this scenario

  • Components Requiring Rework: 40 units (held at the documented default)
  • Rework Labor & Materials per Unit: 950 $/unit (held at the documented default)
  • Confirmed Nonconformance Rate: 54 % (the input this scenario stresses; the baseline uses 75)
  • Crane Access & Retest Charge: 6,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Rework cost = flagged components x rework cost per unit x nonconformance rate% + access/retest.
  • Total rework cost works out to 26,520 $ at these inputs, and this is the headline figure for the scenario.
  • Rework cost per unit works out to 663 $ / piece at these inputs.
  • Variable rework cost works out to 20,520 $ at these inputs.
  • Fixed rework cost adder works out to 6,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where confirmed nonconformance rate sits at 75% and the headline result is 34,500 $, this scenario comes in 23.13% below the baseline at 26,520 $.
  • Use it after an inspection or NDT campaign to price corrective work, or during a supplier claim to quantify the cost of nonconformance. 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 rework cost: 26,520 $ (headline result)
  • Rework cost per unit: 663 $ / piece
  • Variable rework cost: 20,520 $
  • Fixed rework cost adder: 6,000 $
