OEE vs TEEP vs OOE — A Decision Framework for Manufacturers
TL;DR
OEE measures performance during scheduled production time. TEEP measures performance against all calendar time (24/7/365). OOE measures performance during operating time (staffed time). Use OEE for operational improvement (80% of cases), TEEP for strategic capacity decisions (15%), and OOE for shift-addition evaluation (5%). Picking the wrong metric leads to misleading capacity comparisons and bad investment decisions.
OEE measures scheduled production time only; TEEP measures all calendar time (24/7/365); OOE measures operating time including staffed-but-idle periods.
OEE, TEEP, and OOE are three closely-related manufacturing productivity metrics that measure different time periods.
Choosing the wrong one leads to misleading comparisons (a 30% TEEP plant looks worse than a 60% OEE plant on the same operation) and bad strategic decisions (under-investing in capacity expansion because the OEE looks acceptable).
This guide provides a 4-scenario decision framework to pick the right metric.
The 3 metrics in 1 sentence each
OEE = scheduled-time productivity (Availability × Performance × Quality on planned production time).
TEEP = calendar-time productivity (OEE × Utilization, where Utilization = scheduled time ÷ 8,760 hours/year).
OOE = operating-time productivity (similar to OEE but includes staffed-but-idle time in the denominator).
OEE — when to use it
Use OEE when: improving performance during scheduled production, comparing shifts/lines, setting operator improvement targets. OEE is the right metric for ~80% of operational improvement work.
Mid-market median OEE: 60%. World-class: 85%. Read the OEE guide.
TEEP — when to use it
Use TEEP when: evaluating capacity expansion (add shifts vs buy new equipment), justifying capital investment, comparing against 24/7 plants. TEEP is the right metric for strategic capacity decisions.
Mid-market TEEP for 2-shift operations: 30-35%. World-class: 60%+ (requires 24/7 operation). The gap between OEE and TEEP shows your capacity expansion opportunity without buying new equipment.
OOE — when to use it
Use OOE when: evaluating shift-addition decisions, comparing plants with different shift schedules. OOE captures unstaffed time as recoverable.
OOE is rarely used outside this specific scenario — the difference between OEE and OOE matters only for plants considering adding/removing shifts.
4-scenario decision framework
Scenario 1 — Operator improvement target. Use OEE. Operators control what happens during their shift, not whether the plant runs nights/weekends.
Scenario 2 — Shift addition decision. Use TEEP first to evaluate the gap; OOE for detailed shift-by-shift analysis.
Scenario 3 — Capital investment justification. Use TEEP. If TEEP is 30% and OEE is 70%, adding shifts is cheaper than buying equipment.
Scenario 4 — Cross-plant comparison. Use OEE. TEEP comparisons are misleading if shift schedules differ.
Real-world example — 5-line packaging plant
5-line plant, 2 shifts × 5 days × 50 weeks = 4,000 scheduled hours/year. Calendar time = 8,760 hours.
- Utilization = 4,000 ÷ 8,760 = 45.7%
- OEE = 65% (good for 2-shift operation)
- TEEP = 0.65 × 0.457 = 29.7%
The 35-point gap between OEE (65%) and TEEP (30%) signals enormous unused capacity. Adding a 3rd shift (TEEP up to 45%) is often more cost-effective than buying a 6th line.

Frequently Asked Questions
What is the difference between OEE and TEEP?
OEE measures performance during scheduled production time only. TEEP measures performance against all calendar time (24/7/365). TEEP = OEE × Utilization. Use OEE for operational improvement; use TEEP for capacity expansion decisions.
What does TEEP stand for?
TEEP stands for Total Effective Equipment Performance. It captures both equipment effectiveness (OEE) and equipment utilization (% of calendar time scheduled), giving a complete view of total available capacity.
What is a good TEEP score?
World-class TEEP is 60%+ (requires 24/7 operation). For 2-shift operations, world-class is around 45%. For 1-shift operations, world-class is around 22%. Compare TEEP within plants of similar shift patterns; otherwise compare OEE instead.
Can TEEP be higher than OEE?
No. TEEP is mathematically always lower than or equal to OEE because TEEP = OEE × Utilization, and Utilization is always ≤100%. Only continuous 24/7 plants approach TEEP = OEE.
Should I track OEE or TEEP for daily operations?
Track OEE for daily operations and operator improvement. Track TEEP quarterly for strategic capacity planning. Most plants use OEE as primary KPI on shift dashboards and review TEEP in quarterly capacity reviews.
What is OOE?
OOE (Overall Operations Effectiveness) measures performance during operating time, which includes all available shifts (staffed or unstaffed) but excludes intentionally unscheduled time. It is a middle ground between OEE and TEEP, mostly used when evaluating shift addition decisions.
