How to use the result
Availability identifies time loss
Availability compares operating time with planned production time. Agree whether breaks, planned cleaning, scheduled maintenance and changeovers sit inside or outside the planned boundary. Changing the rule between reports makes trends unreliable.
Performance identifies speed loss
Performance compares actual output during run time with the output expected at the approved ideal cycle. A result above 100% is normally a signal to check the ideal cycle, count, units or runtime rather than evidence of impossible extra capacity.
Quality identifies rejected production
Quality uses accepted packs divided by total packs. Record reject reasons at filling, closing, labelling, coding, inspection and secondary packing so improvement work targets the dominant loss rather than the easiest issue to see.
Common questions
What is the OEE formula?
OEE is availability multiplied by performance multiplied by quality, with each factor calculated from the same production boundary.
What is a good OEE for a packaging line?
A useful target depends on product variety, changeover frequency, line maturity and business requirements. Trend each loss category and improve the constraint rather than using a generic benchmark alone.
Why can performance exceed 100%?
The ideal cycle, runtime, product count or unit basis is usually wrong or inconsistent.
Should planned changeovers be included?
Use a documented policy that reflects the question being answered, then apply it consistently across every report.
