Question 1

What is a good OEE score?

Accepted Answer

World-class OEE is 85%. Most manufacturing plants average 60-65%. An OEE of 40% is not uncommon for plants just starting to track OEE. A score of 100% means perfect production: only good parts, at maximum speed, with no downtime.

Question 2

How is OEE different from TEEP?

Accepted Answer

OEE measures effectiveness during planned production time only. TEEP (Total Effective Equipment Performance) considers all calendar time (24/7), including planned shutdowns. TEEP = OEE × Utilization, where Utilization = Planned Time / Calendar Time.
