TEEP: Total Effective Equipment Performance Explained

Key takeaways

• TEEP (Total Effective Equipment Performance) measures equipment effectiveness against all calendar time, including hours the plant was not scheduled to run. OEE measures effectiveness only during scheduled time.
• The formula is simple: TEEP = OEE x Utilization, where Utilization is the share of total calendar time the equipment was scheduled to run.
• TEEP answers a different question than OEE. OEE asks "how well did we run when we were running?" TEEP asks "how much of our total capacity are we actually using?"
• Use TEEP for capacity and investment decisions, not for day-to-day floor management. A low TEEP with high OEE often means you can meet more demand by scheduling more, before buying another machine.

What TEEP is

TEEP takes the OEE idea and widens the lens to the full calendar. Where OEE looks only at the time you planned to produce, TEEP looks at every hour the equipment physically existed: nights, weekends, unscheduled shifts, and idle periods included. It tells you what fraction of the theoretical maximum (24 hours a day, 7 days a week, at full speed, perfect quality) you are actually capturing.

That makes TEEP a blunt but honest capacity number. A machine running three shifts at 85% OEE looks excellent on OEE, but if it sits idle every weekend, its TEEP reveals a large pool of unused capacity.

TEEP versus OEE

The two are complementary, not competing. The difference is the time base:

• OEE = Availability x Performance x Quality, measured over scheduled production time. It is an operational metric for how well the line runs while it is supposed to.
• TEEP = OEE x Utilization, measured over all calendar time. It is a strategic metric for how much of your total capacity you are using.

The pillar on OEE for manufacturing covers the OEE side in full, and manufacturing KPIs covers where both sit among other metrics.

A worked example

Take a line over one week (168 calendar hours). It is scheduled for two shifts, five days: 80 hours. During those 80 hours it runs at 80% OEE. Utilization is 80 / 168 = 48%. So TEEP = 80% x 48% = about 38%.

The OEE of 80% says the line runs well when scheduled. The TEEP of 38% says nearly two thirds of the calendar is unused. If demand rises, adding a third shift is likely cheaper than buying a second machine, and the TEEP number is what makes that visible.

When to use TEEP

• Capacity planning. Before approving capital for new equipment, check TEEP. Spare calendar capacity is cheaper to use than to buy.
• Investment cases. A capex request to add a machine is stronger or weaker depending on whether existing TEEP shows headroom.
• Bottleneck decisions. On a constraint asset, low TEEP points to scheduling fixes before engineering ones. See downtime versus uptime for the availability side.

Common mistakes

• Using TEEP for daily management. It is a capacity metric. Driving operators against TEEP punishes them for scheduling decisions they do not control. OEE is the floor-level number.
• Confusing low TEEP with poor performance. A line can have world-class OEE and low TEEP simply because demand does not require more shifts. That is not a problem, it is a choice.
• Ignoring the utilization term. TEEP without an honest utilization figure is just OEE with extra steps.

How Fabrico fits

Fabrico measures OEE from automatically captured production and downtime data, and because it tracks the full calendar of each asset, the utilization term needed for TEEP comes from the same source rather than a separate spreadsheet. That means OEE for the floor and TEEP for capacity decisions both rest on the same trustworthy data. Fabrico is built and hosted in the EU with data residency in mind and is ISO 27001 certified.

Frequently asked questions

What is the difference between OEE and TEEP?

OEE measures how effectively equipment runs during scheduled production time. TEEP measures effectiveness against all calendar time, including unscheduled hours, by multiplying OEE by utilization. OEE is operational; TEEP is about total capacity use.

What is a good TEEP score?

There is no universal target, because TEEP depends on how many shifts you choose to run. A plant running one shift by design will have a low TEEP and that may be perfectly fine. Compare TEEP to your own trend and to demand, not to an external benchmark.

How is TEEP calculated?

TEEP = OEE x Utilization. Utilization is scheduled production time divided by all calendar time in the period. So TEEP is effectively OEE measured over the full 24/7 calendar rather than just scheduled hours.

When should we use TEEP instead of OEE?

Use TEEP for strategic capacity and investment questions ("do we have headroom or do we need to buy?"). Use OEE for day-to-day operational management. They answer different questions and work best together.
