PLM, BOM & Digital Thread worked example

Part Revision Workload at 12% review, routing, and approval allowance: a worked example

Push review, routing, and approval allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when part revision workload in plm, bom and digital thread needs a defensible run time before a quote goes out.

The inputs for this scenario

  • Part revisions to process: 120 units (unchanged)
  • Revisions processed 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 part revision workload time = part revision workload workload รท part revision workload completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required part revision workload time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base part revision workload time.
  • At this operating point the engine returns 12 % for part revision workload allowance applied.
  • At this operating point the engine returns 12 pieces / min for part revision 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.
  • It converts a batch of part revisions into the engineering hours required, applying an allowance for review and approval overhead. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required part revision workload time: 11.2 hr (headline result)
  • Base part revision workload time: 10 hr
  • Part revision workload allowance applied: 12 %
  • Part revision workload completion rate: 12 pieces / min
