CALCULATE TEEP
THE BIG IDEA
OEE reveals how much of your Planned Production Time is truly productive, but TEEP also takes Utilization into account to show how much potential you have to increase throughput with the equipment you already own.
WHAT IS TEEP?
TEEP (Total Effective Equipment Performance) is a performance metric that provides insights as to the true capacity of your manufacturing operation. It takes account both Equipment Losses (as measured by OEE) and Schedule Losses (as measured by Utilization).

Let’s briefly contrast OEE and TEEP:
- OEE measures the percentage of Planned Production Time that is truly productive.
- TEEP measures the percentage of All Time that is truly productive.
If your TEEP score is 100% then you are making only Good Parts, as fast as possible, with no stops, around the clock (24/7). In other words, you have no Schedule Losses and no OEE Losses.

OEE and TEEP |
OEE is the ratio of Fully Productive Time to Planned Production Time. It takes into account the Six Big Losses. TEEP is the ratio of Fully Productive Time to All Time. It takes into account Schedule Losses and Six Big Losses. |
OEE is improving. Great job! Or is it? Dig a little deeper and the picture is less clear. Most companies would not want to increase Availability by 5.0% at the expense of decreasing Quality by 4.5%.
CALCULATION EXAMPLE
Now let’s work through a complete example using the preferred OEE calculation. Here is data recorded for the first shift:

HOW IS TEEP CALCULATED
TEEP is calculated as:
TEEP = OEE × Utilization
Utilization is calculated as:
Utilization = Planned Production Time / All Time
Here is a simple example, based on a manufacturing operation with a 65% OEE score, that is running two 8-hour shifts per day, five days per week.

MANUFACTURING CAPACITY AND EQUIPMENT UTILIZATION
Capacity can be defined as “the amount that can be produced”. From a discrete manufacturing perspective, we can define capacity as “the maximum number of parts that can be manufactured”. Capacity is fundamentally a part-based metric (e.g., our current capacity is 24,000 red widgets per hour).
Utilization can be defined as “how much something is used”. From a discrete manufacturing perspective, we can define utilization as “the proportion of time that manufacturing equipment is used”. Utilization is fundamentally a percentage-based metric (e.g., our current utilization is 47.62%).
TEEP AND LOSSES
As stated above, TEEP takes into account both Schedule Losses and OEE Losses. Interestingly, losses can be viewed from three perspectives:
- Part Units (we lost 1,000 units of potential production)
- Time Units (we lost two hours of production)
- Percentage Units (we lost 17% of our Planned Production Time)
All three perspectives can be useful – depending on whether you are thinking in terms of sales/capacity (part units), labor/utilization (time units), or manufacturing performance (percentage units).
Measuring TEEP reveals these losses in full so that you can begin to understand and utilize the entire capacity of your plant.
