Production Rework Rate
Production rework rate is the percentage of output requiring additional processing or correction before it can meet acceptance requirements.
What this term means in maintenance
Production rework rate is the percentage of output requiring additional processing or correction before it can meet acceptance requirements.
Formula
Rework rate = Reworked quantity ÷ Total production quantity × 100
Practical example
A process produces 1,500 units and 75 require correction.
Rework rate = 5%
Equipment-related causes
Rework may be associated with:
- Tool condition
- Sensor drift
- Incorrect adjustment
- Temperature
- Pressure
- Alignment
- Wear
- Inconsistent cycle
Rework versus scrap
Reworked output can be recovered through additional effort.
Scrap cannot be economically recovered.
Common mistake
Counting successfully reworked units only as good output hides the original quality loss and extra cost.

Scrap Rate
Scrap rate is the percentage of produced material or units that cannot be accepted or economically reworked.
Production Yield
Production yield is the proportion of input or total produced quantity that becomes acceptable output without being lost as scrap or rejected material.
Quality Rate
Quality rate is the OEE component measuring the proportion of total production that meets the defined good-output requirement.
Production Rework Rate FAQs
- What is production rework rate?
The share of output requiring additional correction before acceptance.
- How is it different from maintenance rework?
Production rework corrects product; maintenance rework corrects deficient maintenance execution.
- Should reworked units remain visible?
Yes. Treating them only as good output hides quality loss and added cost.
