Trailers, Truck Bodies & Specialty Vehicles worked example

Rework Allowance with good units available after first-pass build of 310 units: a worked example in trailers, truck bodies & specialty vehicles

This scenario runs the rework allowance calculation on the strong side: good units available after first-pass build of 310 units, with every other input held at its documented default. Use it when rework allowance in trailers, truck bodies and specialty vehicles needs a clean margin number for a trailers, truck bodies and specialty vehicles go / no-go review.

The inputs for this scenario

  • Good units available after first-pass build: 310 units (raised for this scenario; the documented default is 125)
  • Units required to fulfill the order: 100 units (unchanged)
  • Reference batch size for percentage: 100 units (unchanged)

Working through the calculation

  • Applying the documented formula (Rework Allowance margin = available value - required value) to the inputs above produces each figure below.
  • At this operating point the engine returns 210 % for margin, the number this scenario is built around.
  • At this operating point the engine returns 210 value for absolute margin.
  • At this operating point the engine returns 310 value for available amount.
  • At this operating point the engine returns 100 value for required amount.

How this compares with the baseline

  • Against the tool's baseline example, where good units available after first-pass build sits at 125 units and the headline result is 25 %, this scenario comes in 740% above the baseline at 210 %.
  • Use it at batch release and again after first-pass inspection to confirm you still have enough conforming units to cover the order plus expected rework losses. 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

  • Margin: 210 % (headline result)
  • Absolute margin: 210 value
  • Available amount: 310 value
  • Required amount: 100 value
