What Is TEEP (Total Effective Equipment Performance)? Definition, Formula, and Examples

TEEP (Total Effective Equipment Performance) is a manufacturing metric that measures how effectively a piece of equipment is used relative to all available calendar time — 24 hours a day, 7 days a week, 365 days a year — not just the hours it was scheduled to run.

Definition

TEEP extends OEE (Overall Equipment Effectiveness) by adding a fourth dimension: Loading. OEE tells you how efficiently you use the time you planned to produce. TEEP tells you how efficiently you use all the time that exists.

The Loading factor is the ratio of planned production time to total calendar time. A machine running one 8-hour shift in a 24-hour day has a Loading of 33%. Even with a perfect OEE of 100%, its TEEP would be capped at 33%.

This distinction matters because OEE can look healthy while the business still has significant hidden capacity. TEEP makes that hidden capacity visible.

World-class TEEP benchmark: 85% or higher. Most manufacturing plants operate between 40–65% TEEP, which means substantial untapped theoretical capacity exists — whether or not it makes business sense to exploit it.

Formula / Calculation

TEEP = Availability × Performance × Quality × Loading

Or equivalently:

TEEP = OEE × Loading

Where:

Loading = Planned Production Time ÷ Total Calendar Time

Component definitions:

• Availability — actual run time ÷ planned production time (accounts for breakdowns and changeovers)
• Performance — actual output rate ÷ ideal output rate (accounts for slow cycles and minor stops)
• Quality — good units produced ÷ total units started (accounts for defects and rework)
• Loading — planned production time ÷ total calendar time (the factor OEE ignores)

Manufacturing Example

Consider a CNC machining center at a job shop:

The OEE of 77.7% looks reasonable. The TEEP of 51.8% reveals that the machine is only producing value during roughly half of all available calendar time. Before investing in a third machine, management can ask whether adding a third shift would cost less.

Why It Matters for Production Scheduling

TEEP is most valuable when making capital allocation decisions. If your plant's TEEP is 45%, buying another machine before optimizing shift patterns is often the wrong investment. The capacity is already there — it just is not being scheduled.

For schedulers using tools like RMDB, TEEP data highlights which work centers have untapped third-shift or weekend capacity. That information changes how finite capacity scheduling allocates overloaded jobs: instead of flagging a bottleneck, the scheduler can propose a shift extension on the constrained machine.

TEEP also appears in lease-or-buy analyses. A machine with 30% TEEP has room to absorb contract work or new product lines before a capital expenditure is justified.

TEEP vs. OEE

Use OEE to drive daily operational improvement on the shop floor. Use TEEP when the question is strategic: "Do we need more machines, or more shifts?"

How to Improve TEEP

• Increase Loading by evaluating whether adding shifts is economically viable — this is the single highest-leverage TEEP lever for single-shift plants.
• Improve OEE through faster changeovers (SMED), predictive maintenance, and defect reduction — all gains flow through to TEEP automatically.
• Schedule weekend or holiday production for high-demand periods rather than defaulting to overtime on weekdays.
• Identify low-utilization assets using TEEP dashboards and consider whether they can be redeployed, sold, or leased to other manufacturers.
• Use finite capacity scheduling software to model the TEEP impact of shift pattern changes before committing to them operationally.
