NPI, DFM/DFA & Engineering Change worked example
Validation Build Quantity at 9.2% throughput efficiency factor: a worked example
This scenario runs the validation build quantity calculation on the strong side: 9.2% throughput efficiency factor, with every other input held at its documented default. Use it when validation build quantity in npi, dfm/dfa and engineering change is being sized against an asset rating.
The inputs for this scenario
- Validation units required: 100 units (unchanged)
- Available build capacity per hour: 1.2 units (unchanged)
- Throughput efficiency factor: 9.2 % (raised for this scenario; the documented default is 8)
Working through the calculation
- Applying the documented formula (Required validation build quantity load = validation build quantity demand รท validation build quantity 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 throughput efficiency factor sits at 8% and the headline result is 120 hr, this scenario lands almost exactly on the baseline at 120 hr.
- Use it when planning a validation, pilot or capability-study build on a line that is not yet at full mature throughput. 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
