Commercial Vehicle, Bus & Coach Manufacturing worked example

Harness Routing Labor at 110% harness scope included: a worked example in commercial vehicle, bus & coach manufacturing

What does the result look like when harness scope included reaches 110%? The full calculation is worked below with real intermediate numbers. costing vehicle wiring harness routing labor

The inputs for this scenario

  • Vehicles requiring harness routing: 16 units (unchanged)
  • Harness routing labor cost per vehicle: 2,350 $ / unit (unchanged)
  • Harness scope included: 110 % (raised for this scenario; the documented default is 100)
  • Harness fixture, test, and engineering support cost: 5,200 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable harness routing labor = vehicles requiring harness routing × harness routing labor cost per vehicle × harness scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 46,560 $ for total harness routing labor, the number this scenario is built around.
  • At this operating point the engine returns 2,910 $ / piece for harness routing labor per vehicle.
  • At this operating point the engine returns 41,360 $ for variable harness routing labor.
  • At this operating point the engine returns 5,200 $ for harness fixture, test, and engineering support cost.

How this compares with the baseline

  • Against the tool's baseline example, where harness scope included sits at 100% and the headline result is 42,800 $, this scenario comes in 8.79% above the baseline at 46,560 $.
  • A figure at this level is achievable when harness scope included is genuinely sustained, not just peaked for a shift. It uses one routing labor figure per vehicle, but harness complexity varies by option content, so a fully optioned coach can route far slower than the base build; cost variants separately.

Results at a glance

  • total harness routing labor: 46,560 $ (headline result)
  • harness routing labor per vehicle: 2,910 $ / piece
  • variable harness routing labor: 41,360 $
  • harness fixture, test, and engineering support cost: 5,200 $
