Rework Cost at 110% rework scope included: a worked example in construction machinery & attachments

This scenario runs the rework cost calculation on the strong side: 110% rework scope included, with every other input held at its documented default. prioritizing attachment quality issues by cost impact

The inputs for this scenario

  • Attachment rework events: 18 events (unchanged)
  • Average rework cost per event: 690 $ / event (unchanged)
  • Rework scope included: 110 % (raised for this scenario; the documented default is 100)
  • Fixed containment and corrective action cost: 1,800 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable rework cost = attachment rework events × average rework cost per event × rework scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 15,462 $ for total attachment rework cost, the number this scenario is built around.
  • At this operating point the engine returns 859 $ / piece for rework cost per event.
  • At this operating point the engine returns 13,662 $ for variable rework cost.
  • At this operating point the engine returns 1,800 $ for fixed containment and corrective action 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 14,220 $, this scenario comes in 8.73% above the baseline at 15,462 $.
  • Use it when quantifying the cost of a defect trend, building a cost-of-quality case, or comparing rework spend to a prevention investment. 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 attachment rework cost: 15,462 $ (headline result)
  • rework cost per event: 859 $ / piece
  • variable rework cost: 13,662 $
  • fixed containment and corrective action cost: 1,800 $
