If Availability is 100%, Performance is 100%, and OEE is 90%, what is the Value Stream Quality percentage?

• A. 100%
• B. 90%
• C. 81%
• D. Cannot be calculated

Answer: (B)

OEE is made up of three factors that multiply together: Availability, Performance, and Quality. If Availability is 100% and Performance is 100%, their product is 1.0. With OEE at 90% (0.9), the remaining factor must be 0.9, which is the Quality portion. So the Value Stream Quality percentage is 90%. This means about 90% of produced items are good, while the remaining 10% are not acceptable, causing the OEE to be 0.9.
