Production Ramp, Scale-Up & Launch Readiness worked example
Line Qualification Workload at 7.2% setup, changeover, and inspection allowance: a worked example
This worked example runs the line qualification workload numbers for a tougher week than the baseline: 7.2% setup, changeover, and inspection allowance instead of the typical 10%. Estimate line qualification workload for production ramp, scale-up and launch readiness using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.
The inputs for this scenario
- Qualification units to run and inspect: 120 units (held at the documented default)
- Qualified line throughput: 12 units / min (held at the documented default)
- Setup, changeover, and inspection allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)
Working through the calculation
- The calculation starts from the formula this tool documents: Base line qualification workload time = line qualification workload workload รท line qualification workload completion rate.
- Required line qualification workload time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
- Base line qualification workload time works out to 10 hr at these inputs.
- Line qualification workload allowance applied works out to 7.2 % at these inputs.
- Line qualification workload completion rate works out to 12 pieces / min at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where setup, changeover, and inspection allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
- Use it during launch readiness planning to reserve line time for qualification runs, PPAP builds, or capability studies before production sign-off. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
