Warehouse Error Cost at 75% customer-impacting share: a worked example

Push customer-impacting share up to 75% and the picture changes. This example computes every intermediate figure at that operating point. A quality lead sizes the cost of mispicks and misships to prioritize barcode scanning or pick-to-light investment.

The inputs for this scenario

  • Errors detected per period: 180 errors (unchanged)
  • Cost per error: 42 $/error (unchanged)
  • Customer-impacting share: 75 % (raised for this scenario; the documented default is 65)
  • Audit and QA overhead: 600 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total cost = errors detected x cost per error x customer-impacting share% + audit and QA overhead) to the inputs above produces each figure below.
  • At this operating point the engine returns 6,270 $ for total warehouse error cost, the number this scenario is built around.
  • At this operating point the engine returns 34.83 $ / piece for warehouse error cost per unit.
  • At this operating point the engine returns 5,670 $ for variable warehouse error cost.
  • At this operating point the engine returns 600 $ for fixed warehouse error cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where customer-impacting share sits at 65% and the headline result is 5,514 $, this scenario comes in 13.71% above the baseline at 6,270 $.
  • It multiplies detected errors by cost per error and the customer-impacting share, then adds fixed audit and QA overhead to report total error cost and cost per error. 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.
