Quality worked example

Yield with input units started of 5,000 units: a worked example

Push input units started up to 5,000 units and the picture changes. This example computes every intermediate figure at that operating point. Use when output quality needs a simple good-part percentage.

The inputs for this scenario

  • Input units started: 5,000 units (raised for this scenario; the documented default is 2,000)
  • Good units out: 1,908 units (unchanged)
  • Scrapped units: 58 units (unchanged)
  • Reworked units: 34 units (unchanged)

Working through the calculation

  • Applying the documented formula (Yield = good units รท input units) to the inputs above produces each figure below.
  • At this operating point the engine returns 38.16 % for yield, the number this scenario is built around.
  • At this operating point the engine returns 61.84 % for loss rate.
  • At this operating point the engine returns 1.16 % for scrap rate.
  • At this operating point the engine returns 0.68 % for rework rate.

How this compares with the baseline

  • Against the tool's baseline example, where input units started sits at 2,000 units and the headline result is 95.4 %, this scenario comes in 60% below the baseline at 38.16 %.
  • It computes overall process yield as good units divided by units started, plus the loss, scrap, and rework rates that make up the gap. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

  • Yield: 38.16 % (headline result)
  • Loss rate: 61.84 %
  • Scrap rate: 1.16 %
  • Rework rate: 0.68 %
