  3. Check the method and assumptions below before using the result.

The method, explained

First pass yield = units passing without rework / units entering × 100.

A WORKED EXAMPLE

Using units passing first attempt = 960 units, units entering process = 1000 units, the result is 96 %. Change these example inputs to match your task; use the method above to check each step.

Understanding your result

Count each unit once. Final yield after rework is a different metric and can hide rework burden.

What to keep in mind

Count each unit once. Final yield after rework is a different metric and can hide rework burden. Use consistent currencies, reporting periods and accounting definitions. This arithmetic estimate excludes items not entered in the form.
