NPI, DFM/DFA & Engineering Change worked example

Drawing Release Cycle Time at 12% setup, handling, and delay allowance: a worked example

This scenario runs the drawing release cycle time calculation on the strong side: 12% setup, handling, and delay allowance, with every other input held at its documented default. Use it when drawing release cycle time in npi, dfm/dfa and engineering change is being added to next week's schedule and you need an honest hours estimate.

The inputs for this scenario

  • Drawing release cycle time workload: 120 units (unchanged)
  • Drawing release cycle time completion rate: 12 units / min (unchanged)
  • Setup, handling, and delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and delay 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 when committing a drawing release milestone for an NPI build, sizing a checker's weekly queue, or quoting turnaround for an ECO drawing batch. 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 cycle time: 11.2 hr (headline result)
  • Base drawing release cycle time: 10 hr
  • Drawing release cycle time allowance applied: 12 %
  • Drawing release cycle time completion rate: 12 pieces / min

Run it with your numbers

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