Wire Harness, Cable & Electromechanical Assembly worked example

Harness Changeover Time at 12% setup, handling, and delay allowance: a worked example

This scenario runs the harness changeover time calculation on the strong side: 12% setup, handling, and delay allowance, with every other input held at its documented default. Use it when harness changeover time in wire harness, cable and electromechanical assembly is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Changeover tasks to complete between builds: 120 units (unchanged)
  • Changeover tasks completed per minute: 12 units / min (unchanged)
  • Setup, handling, and delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base harness changeover time = harness changeover time workload รท harness changeover time completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required harness changeover time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base harness changeover time.
  • At this operating point the engine returns 12 % for harness changeover time allowance applied.
  • At this operating point the engine returns 12 pieces / min for harness changeover time completion rate.

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 1.82% above the baseline at 11.2 hr.
  • Use it when planning batch runs, scheduling changeovers, or building a baseline before a SMED improvement effort. 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

  • Required harness changeover time: 11.2 hr (headline result)
  • Base harness changeover time: 10 hr
  • Harness changeover time allowance applied: 12 %
  • Harness changeover time completion rate: 12 pieces / min

Run it with your numbers

  • Every input above is editable in the live Harness Changeover Time calculator, which recalculates instantly and can be shared with the inputs intact.
