PLM, BOM & Digital Thread worked example

Drawing Release Backlog at 12% check, sign-off, and distribution allowance: a worked example

This scenario runs the drawing release backlog calculation on the strong side: 12% check, sign-off, and distribution allowance, with every other input held at its documented default. Use it when drawing release backlog in plm, bom and digital thread is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Drawings awaiting release: 120 units (unchanged)
  • Drawings released per minute: 12 units / min (unchanged)
  • Check, sign-off, and distribution allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where check, sign-off, and distribution 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 during NPI ramp, before a production start, or whenever a release queue is backing up and threatening downstream schedules. 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 drawing release backlog time: 11.2 hr (headline result)
  • Base drawing release backlog time: 10 hr
  • Drawing release backlog allowance applied: 12 %
  • Drawing release backlog completion rate: 12 pieces / min

Run it with your numbers

  • Every input above is editable in the live Drawing Release Backlog calculator, which recalculates instantly and can be shared with the inputs intact.
