PLM, BOM & Digital Thread worked example

Part Revision Workload at 7.2% review, routing, and approval allowance: a worked example

This worked example runs the part revision workload numbers for a tougher week than the baseline: 7.2% review, routing, and approval allowance instead of the typical 10%. Estimate part revision workload for plm, bom and digital thread 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

  • Part revisions to process: 120 units (held at the documented default)
  • Revisions processed per minute: 12 units / min (held at the documented default)
  • Review, routing, and approval 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 part revision workload time = part revision workload workload รท part revision workload completion rate.
  • Required part revision workload time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base part revision workload time works out to 10 hr at these inputs.
  • Part revision workload allowance applied works out to 7.2 % at these inputs.
  • Part revision workload completion rate works out to 12 pieces / min at these inputs.

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 2.55% below the baseline at 10.72 hr.
  • Use it when planning ECO campaigns, sizing a revision backlog, or committing a release date to a customer or program. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Required part revision workload time: 10.72 hr (headline result)
  • Base part revision workload time: 10 hr
  • Part revision workload allowance applied: 7.2 %
  • Part revision workload completion rate: 12 pieces / min
