Wire Harness, Cable & Electromechanical Assembly worked example

Routing Labor at 7.2% setup, handling, and delay allowance: a worked example

Suppose setup, handling, and delay allowance falls to 7.2%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate routing labor for wire harness, cable and electromechanical assembly using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.

The inputs for this scenario

  • Wires or circuits to route: 120 units (held at the documented default)
  • Circuits routed per minute on the board: 12 units / min (held at the documented default)
  • Setup, handling, and delay allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base routing labor time = routing labor workload รท routing labor completion rate.
  • Required routing labor time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base routing labor time works out to 10 hr at these inputs.
  • Routing labor allowance applied works out to 7.2 % at these inputs.
  • Routing labor completion rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and delay allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • It computes the required routing labor hours by dividing the number of wires to route by the routing rate, then multiplying by an allowance factor for setup, handling, and delay. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Required routing labor time: 10.72 hr (headline result)
  • Base routing labor time: 10 hr
  • Routing labor allowance applied: 7.2 %
  • Routing labor completion rate: 12 pieces / min

Run it with your numbers

  • To rerun this with your own numbers, open the live Routing Labor calculator, set setup, handling, and delay allowance to your actual value, and adjust the remaining inputs to match your operation.
