TEEP Explained: Total Effective Equipment Performance

TEEP (Total Effective Equipment Performance) is a manufacturing metric that measures how much of your total calendar time an asset spends producing good parts at full speed. It multiplies Utilization by OEE, so it accounts for all 8,760 hours in a year, including unscheduled time such as nights, weekends, and idle shifts.

What TEEP Measures And Why It Differs From OEE

TEEP answers a question OEE cannot: how much untapped capacity is hiding in your existing equipment. While OEE measures effectiveness only during planned production time, TEEP stretches the denominator to cover every hour the calendar offers.

• OEE uses planned production time as its baseline, so it excludes unstaffed shifts and planned closures.
• TEEP uses total calendar time (24 hours a day, 365 days a year) as its baseline, so nothing is excluded.

The practical result: OEE tells you how well you run when you choose to run, while TEEP tells you how much more you could produce if you ran the asset around the clock. TEEP is always lower than OEE for the same machine.

The TEEP Formula

TEEP is built from two components, one of which is OEE itself. The formula is deliberately simple:

1. TEEP = Utilization x OEE
2. Utilization = Planned Production Time / Total Calendar Time
3. OEE = Availability x Performance x Quality

Utilization is the new factor here. It captures the gap between the time you schedule the machine and the total time it physically exists to run. A single-shift operation that idles the machine two-thirds of every day will carry a low Utilization score no matter how flawless its OEE.

A Worked Numeric Example

Numbers make the distinction concrete. Consider a CNC cell over one standard week.

• Total calendar time: 7 days x 24 hours = 168 hours
• Planned production time: 5 days x 8 hours = 40 hours
• Measured OEE during those 40 hours: 82%

First calculate Utilization:

• Utilization = 40 / 168 = 0.238 (23.8%)

Then multiply by OEE:

• TEEP = 0.238 x 0.82 = 0.195, or 19.5%

The cell runs at a healthy 82% OEE, yet its TEEP is only 19.5%. That gap is not a failure of the operators; it is a signal that roughly 80% of the asset's theoretical capacity sits unused, mostly because the machine is scheduled for a single shift. This is exactly the insight a capacity or capital-investment decision needs.

Benefits Of Tracking TEEP

TEEP reframes hidden capacity as a strategic number rather than a shop-floor detail. Teams that monitor it gain several advantages.

• Smarter capital decisions: Before buying a new machine, TEEP reveals whether existing assets could absorb the demand with an added shift instead.
• Honest capacity planning: Sales and operations planning gets a realistic ceiling on output rather than an optimistic single-shift figure.
• Clear ROI framing: The gap between OEE and TEEP quantifies the cost of unscheduled time, which helps justify staffing or automation investments.
• Complement to reliability metrics: Paired with MTBF and MTTR, TEEP shows whether reliability gains would actually translate into more sellable output.

When To Use TEEP Versus OEE

Choose the metric that matches the decision in front of you. The two are complementary, not competing.

• Use OEE for day-to-day improvement: reducing changeover time, cutting minor stops, and improving quality within the shifts you already run. It is the right lens for reducing unplanned downtime and driving continuous improvement.
• Use TEEP for strategic questions: whether to add a shift, buy new equipment, outsource, or accept new demand. It exposes the true ceiling of your installed base.

A common pattern is to review OEE weekly with the production team and TEEP monthly or quarterly with operations leadership. TEEP fits naturally inside a broader total productive maintenance program, where the goal is to maximize the return on every asset.

Practical Steps To Start Measuring TEEP

Getting a trustworthy TEEP number depends almost entirely on clean, automatic data capture. Follow these steps.

1. Confirm your total calendar time baseline (usually 24 x 365, or 24 x the number of days in the period).
2. Log actual planned production time per period, including any planned closures you deliberately exclude from OEE.
3. Capture Availability, Performance, and Quality automatically from the machine rather than from manual logs, which drift and undercount micro-stops.
4. Calculate Utilization, then multiply by OEE for each asset and roll the results up by line and plant.
5. Review the OEE-to-TEEP gap regularly and treat large gaps as capacity opportunities, not shop-floor faults.

Real-time production monitoring makes this practical at scale. Fabrico captures OEE and utilization data directly from equipment, including through camera and computer-vision monitoring that works even on machines without a PLC, so TEEP reflects reality instead of estimates.

Frequently Asked Questions

Is TEEP always lower than OEE?

Yes, for any asset that is not run every hour of the calendar. TEEP equals OEE only in the theoretical case where planned production time equals total calendar time, meaning the machine is scheduled 24 hours a day, every day. Because almost every plant has nights, weekends, or idle shifts, Utilization is below 100% and TEEP falls below OEE.

What is a good TEEP score?

There is no universal target because TEEP depends heavily on your shift structure. A single-shift operation may sit near 20% while a continuous 24/7 process could exceed 60%. Rather than chasing a benchmark, track your own TEEP trend over time and use the gap to OEE to decide whether adding shifts or capacity is worthwhile.

How does TEEP relate to CMMS and maintenance?

TEEP exposes lost capacity, and a CMMS helps you recover it. Better preventive maintenance raises the Availability portion of OEE, while smarter scheduling of maintenance windows into unstaffed hours can lift Utilization. Together they turn a low TEEP into a concrete action plan for reclaiming output from equipment you already own.
