PLM, BOM & Digital Thread worked example

Variant Management Workload at 12% setup, review, and handoff allowance: a worked example

What does the result look like when setup, review, and handoff allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when variant management workload in plm, bom and digital thread is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Variant records to process (create, revise, or clean up): 120 units (unchanged)
  • Variant processing throughput per person: 12 units / min (unchanged)
  • Setup, review, and handoff allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where setup, review, and handoff 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 setup, review, and handoff allowance is genuinely sustained, not just peaked for a shift. It assumes a steady average throughput; if variants differ wildly in complexity, split them into tiers and run the calculator per tier.

Results at a glance

  • Required variant management workload time: 11.2 hr (headline result)
  • Base variant management workload time: 10 hr
  • Variant management workload allowance applied: 12 %
  • Variant management workload completion rate: 12 pieces / min
