Door Rework Cost at 72% share of rework events charged to this line: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop share of rework events charged to this line to 72%, then walk the calculation through step by step. Estimate door rework cost from rework events, cost per event, scope, and containment adders.

The inputs for this scenario

  • Door rework events this period: 24 events (held at the documented default)
  • Average labor + material cost per door rework event: 145 $ / event (held at the documented default)
  • Share of rework events charged to this line: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed containment, sorting, and corrective-action cost: 620 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable door rework cost = door rework events × average door rework cost per event × door rework scope included.
  • total door rework cost works out to 3,126 $ at these inputs, and this is the headline figure for the scenario.
  • door rework cost per event works out to 130 $ / piece at these inputs.
  • variable door rework cost works out to 2,506 $ at these inputs.
  • fixed door containment and corrective-action cost works out to 620 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of rework events charged to this line sits at 100% and the headline result is 4,100 $, this scenario comes in 23.77% below the baseline at 3,126 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to share of rework events charged to this line, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Average cost per event hides variation — a single severe rework (full slab scrap) can dwarf a dozen minor adjustments, so pair this with a defect Pareto before acting.

Results at a glance

  • total door rework cost: 3,126 $ (headline result)
  • door rework cost per event: 130 $ / piece
  • variable door rework cost: 2,506 $
  • fixed door containment and corrective-action cost: 620 $
