PLM, BOM & Digital Thread worked example

Change Notice Workload at 12% review, routing, and approval allowance: a worked example

What does the result look like when review, routing, and approval allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when change notice workload in plm, bom and digital thread is being added to next week's schedule and you need an honest hours estimate.

The inputs for this scenario

  • Change notices to process: 120 units (unchanged)
  • Change notices closed per minute: 12 units / min (unchanged)
  • Review, routing, and approval allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where review, routing, and approval allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • A figure at this level is achievable when review, routing, and approval allowance is genuinely sustained, not just peaked for a shift. The single closure rate assumes change notices are roughly uniform in effort; a few complex, multi-BOM changes can dominate actual hours and break the average.

Results at a glance

  • Required change notice workload time: 11.2 hr (headline result)
  • Base change notice workload time: 10 hr
  • Change notice workload allowance applied: 12 %
  • Change notice workload completion rate: 12 pieces / min
