TEEP calculator

Multiply OEE by utilization. Utilization is planned production time divided by all calendar time in the period, and OEE is availability × performance × quality. A line planned for 80 of 168 hours in a week (47.6% utilization) with an OEE of 83.8% has a TEEP of 39.9%.

OEE only looks at the time you planned to run, so a plant that runs one shift can show a high OEE. TEEP measures against every hour in the period, so it also shows the capacity in the shifts, nights and weekends you do not schedule. OEE tells you how well the scheduled time is used; TEEP tells you how much of the machine's full-time potential you are using.

There is no fixed benchmark, because TEEP depends on how many hours you choose to schedule. A plant that runs 24 hours a day, 7 days a week has a TEEP equal to its OEE. A plant that runs one 8-hour shift, 5 days a week can never get above 23.8% (40 of 168 hours), however well it runs. Compare a line with its own TEEP over time, not with another plant's.

Planned stops are taken out of the planned production time, so they lower utilization and therefore TEEP, but they are not counted as a loss inside OEE. The calculator's planned production time should be the hours you scheduled the machine to produce, after breaks and planned maintenance.

Use it before buying capacity. If TEEP is low because the machine is not scheduled, adding a shift may be cheaper than buying another machine. If TEEP is low because OEE is low, fixing availability, performance or quality on the hours you already run comes first.
