Production Ramp, Scale-Up & Launch Readiness worked example

Ramp Learning Curve at 12% setup, handling, and learning-curve delay allowance: a worked example

This scenario runs the ramp learning curve calculation on the strong side: 12% setup, handling, and learning-curve delay allowance, with every other input held at its documented default. Use it when ramp learning curve in production ramp, scale-up and launch readiness is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Units to build during the ramp period: 120 units (unchanged)
  • Steady-state build rate at end of ramp: 12 units / min (unchanged)
  • Setup, handling, and learning-curve delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and learning-curve 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 in the pre-launch and early-ramp window to size crew hours, plan shift coverage, and set realistic daily output commitments before the line hits nameplate rate. 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 ramp learning curve time: 11.2 hr (headline result)
  • Base ramp learning curve time: 10 hr
  • Ramp learning curve allowance applied: 12 %
  • Ramp learning curve completion rate: 12 pieces / min
