Cleaning Rework Cost at 110% rework scope included: a worked example

This scenario runs the cleaning rework cost calculation on the strong side: 110% rework scope included, with every other input held at its documented default. Use it when rewash, manual wipe, extra rinse, or retest activity is consuming production capacity and cost.

The inputs for this scenario

  • Parts requiring cleaning rework: 420 parts (unchanged)
  • Rework cost per part: 1.85 $ / part (unchanged)
  • Rework scope included: 110 % (raised for this scenario; the documented default is 100)
  • Fixed containment and retest cost: 350 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable cleaning rework cost = parts requiring cleaning rework × rework cost per part × rework scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,205 $ for total cleaning rework cost, the number this scenario is built around.
  • At this operating point the engine returns 2.87 $ / part for rework cost per part.
  • At this operating point the engine returns 855 $ for variable cleaning rework cost.
  • At this operating point the engine returns 350 $ for fixed containment and retest cost.

How this compares with the baseline

  • Against the tool's baseline example, where rework scope included sits at 100% and the headline result is 1,127 $, this scenario comes in 6.89% above the baseline at 1,205 $.
  • Use it after a cleanliness failure to cost the containment, or when building a cost-of-poor-quality case to fund washer or chemistry improvements. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total cleaning rework cost: 1,205 $ (headline result)
