NPI, DFM/DFA & Engineering Change worked example
NPI Labor Load at 9.2% planned utilization of npi labor: a worked example
What does the result look like when planned utilization of npi labor reaches 9.2%? The full calculation is worked below with real intermediate numbers. Use it when npi labor load in npi, dfm/dfa and engineering change is being sized against an asset rating.
The inputs for this scenario
- NPI build hours demanded by the launch plan: 100 units (unchanged)
- NPI labor hours available on the floor: 1.2 units (unchanged)
- Planned utilization of NPI labor: 9.2 % (raised for this scenario; the documented default is 8)
Working through the calculation
- Applying the documented formula (Required npi labor load = npi labor load demand รท npi labor load 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 planned utilization of npi labor sits at 8% and the headline result is 120 hr, this scenario lands almost exactly on the baseline at 120 hr.
- A figure at this level is achievable when planned utilization of npi labor is genuinely sustained, not just peaked for a shift. Utilization is an assumption, not a measurement; if your real NPI team runs at 70% effective utilization but you plan for 90%, the required load is understated and the line falls behind.
