How to use this tool

  1. Enter your own assumptions using a consistent currency and period.
  2. Review the scenario outputs and compare alternative inputs.
  3. Check the stated model limits before using the result in an operating plan.

Try this example

{
  "starts": 10000,
  "yield_a": 98,
  "yield_b": 95,
  "yield_c": 97
}

Accuracy and scope

Assumes sequential yields apply to surviving units and no rework recovery. Stage rates are user-supplied.
