Coil Yield by Profile at 68% target coil yield rate: a worked example

This worked example runs the coil yield by profile numbers for a tougher week than the baseline: 68% target coil yield rate instead of the typical 95%. Estimate coil yield by profile for roofing, siding and exterior building products using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Panels rejected for this profile: 8 count (held at the documented default)
  • Total panels formed for this profile: 250 count (held at the documented default)
  • Target coil yield rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Coil yield by profile rate = coil yield by profile count ÷ total coil yield by profile population × 100.
  • Coil yield by profile rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Coil yield by profile gap to target works out to 64.8 points at these inputs.
  • Coil yield by profile count works out to 8 count at these inputs.
  • Total coil yield by profile population works out to 250 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target coil yield rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it per profile after a run or shift to rank which profiles scrap most and to feed a yield improvement backlog. 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.

Results at a glance

  • Coil yield by profile rate: 3.2 % (headline result)
  • Coil yield by profile gap to target: 64.8 points
  • Coil yield by profile count: 8 count
  • Total coil yield by profile population: 250 count

Run it with your numbers
