Fire Suppression, Sprinkler & Safety System Products worked example

Rework Cost at 72% captured rework exposure share: a worked example in fire suppression, sprinkler & safety system products

Here is what the math looks like when conditions slip. We hold every other input steady and drop captured rework exposure share to 72%, then walk the calculation through step by step. Estimate fire protection product rework cost from rework events, cost per event, captured exposure, and fixed containment cost.

The inputs for this scenario

  • Fire protection rework events: 38 events (held at the documented default)
  • Cost per rework event: 42 $ / event (held at the documented default)
  • Captured rework exposure share: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed containment or quality cost: 650 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Rework Cost = fire protection rework events × cost per rework event × captured rework exposure share + fixed containment or quality cost.
  • Total rework cost works out to 1,799 $ at these inputs, and this is the headline figure for the scenario.
  • Average rework cost per unit works out to 47.35 $ / event at these inputs.
  • Variable captured cost works out to 1,149 $ at these inputs.
  • Fixed containment or quality cost works out to 650 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where captured rework exposure share sits at 100% and the headline result is 2,246 $, this scenario comes in 19.9% below the baseline at 1,799 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to captured rework exposure share, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It uses an average cost per event; if your reworks vary widely in severity, a blended average can hide expensive outliers like full lot re-certification.

Results at a glance

  • Total rework cost: 1,799 $ (headline result)
  • Average rework cost per unit: 47.35 $ / event
  • Variable captured cost: 1,149 $
  • Fixed containment or quality cost: 650 $
