OEE vs TEEP vs OOE vs Utilization: Manufacturing Metrics Explained (2026)

Short answer: OEE, OOE, TEEP and Utilization all measure manufacturing productivity, but each uses a different time window. OEE measures how well you run during planned production time; OOE widens the lens to all scheduled operating time; TEEP goes all the way to calendar time (OEE × Utilization) to reveal hidden capacity; and Utilization is the share of calendar time you actually schedule production. Use OEE for daily improvement and TEEP for capacity and investment decisions.

What is OEE?

OEE (Overall Equipment Effectiveness) is the product of three factors — Availability, Performance and Quality — measured against planned production time (the time you intended to run, excluding planned shutdowns). It answers: when we meant to be producing, how much fully-good output did we actually get? It is the go-to metric for daily improvement. See our guide to calculating OEE.

What is OOE?

OOE (Overall Operations Effectiveness) uses the same three factors but a wider time basis: it counts all the time the operation is scheduled to be open, including unplanned stoppages. Because the denominator is larger, OOE is a stricter view of availability and is useful when you want losses judged against the full operating window, not just planned run time.

What is TEEP?

TEEP (Total Effective Equipment Performance) is OEE × Utilization, measured against all calendar time (24 hours a day, 7 days a week). It exposes hidden capacity: a line can have world-class OEE yet a low TEEP simply because it only runs one shift. TEEP is the metric for capacity planning and capex decisions.

What is Utilization?

Utilization is the share of total calendar time that you actually schedule production (scheduled time ÷ calendar time). It is the bridge between OEE and TEEP, and it answers a strategic question: before buying another machine, how much unused calendar time could you convert by adding a shift?

Which metric should you track?

Track OEE for continuous improvement on the floor, and TEEP when you are weighing capacity and investment. Utilization tells you whether the gap is a scheduling choice or a true capacity limit. To see where your OEE stands versus your sector, check the 2026 OEE benchmarks, and compare tools in our OEE software guide.

Frequently asked questions

Is TEEP always lower than OEE?

Yes. TEEP equals OEE multiplied by Utilization, and Utilization is at most 100%, so TEEP is always less than or equal to OEE. The gap is the calendar time you are not scheduling.

What is a good OEE versus a good TEEP?

World-class OEE is around 85%. TEEP is usually much lower because most plants do not run 24/7, so a strong TEEP depends on both high OEE and high scheduled utilization.

What is the difference between OEE and OOE?

The time basis. OEE is measured against planned production time, while OOE is measured against all scheduled operating time including unplanned stoppages, making it a stricter availability view.

Do I need to track all four metrics?

No. Start with OEE for daily improvement, add TEEP and Utilization when you are making capacity or investment decisions. OOE is optional and used when you want a stricter operating-time view.
