NPI, DFM/DFA & Engineering Change worked example

PPAP Workload at 9.2% ppap workload utilization target: a worked example

This scenario runs the ppap workload calculation on the strong side: 9.2% ppap workload utilization target, with every other input held at its documented default. Use it when ppap workload in npi, dfm/dfa and engineering change is being sized against an asset rating.

The inputs for this scenario

  • Ppap workload demand: 100 units (unchanged)
  • Ppap workload capacity: 1.2 units (unchanged)
  • Ppap workload utilization target: 9.2 % (raised for this scenario; the documented default is 8)

Working through the calculation

  • Applying the documented formula (Required ppap workload load = ppap workload demand รท ppap workload utilization target) to the inputs above produces each figure below.
  • At this operating point the engine returns 120 hr for total load, the number this scenario is built around.
  • At this operating point the engine returns 13.04 hr / hr for hourly equivalent.
  • At this operating point the engine returns 100 hr for input load.
  • At this operating point the engine returns 1.2 x for load factor.

How this compares with the baseline

  • Against the tool's baseline example, where ppap workload utilization target sits at 8% and the headline result is 120 hr, this scenario lands almost exactly on the baseline at 120 hr.
  • Use it during launch planning or supplier ramp when the PPAP queue is filling faster than your quality team can clear submissions. 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

  • Total load: 120 hr (headline result)
  • Hourly equivalent: 13.04 hr / hr
  • Input load: 100 hr
  • Load factor: 1.2 x

Run it with your numbers

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