Which of the following is NOT a core component of OEE?

• A. Availability
• B. Utilization
• C. Performance
• D. Quality

Answer: (D)

OEE is built from three measurements: Availability, Performance, and Quality. Availability looks at how much uptime you actually have versus the planned production time, including how long the equipment is down for repairs or setup. Performance checks how fast the equipment runs when it’s actually producing, comparing the real speed to the ideal speed. Quality measures the proportion of good units produced out of all units, isolating losses from defects. Utilization, while it relates to how much of the available time you use, is not one of the three OEE components. It’s a broader concept you might consider alongside OEE, but it isn’t a named part of the OEE calculation. So Utilization is not a core component, whereas Availability, Performance, and Quality are.
