Overall Equipment Effectiveness


If you cannot measure it, you cannot manage it. Overall Equipment Effectiveness, or “OEE,” is a well-known concept in maintenance and is a way of measuring the effectiveness of a machine. It is the backbone of many techniques employed in asset management programs.

This white paper begins with an explanation of the difference between efficiency, effectiveness and productivity. OEE is widely used as a metric to coordinate production strategies and propel manufacturing optimization through production planning, machine reliability, quality and productivity improvements. Implementing OEE on the shop-floor is complex and considers multiple machines types with variable run-times.

This compact one-day training course looks at OEE in detail. You will be able to understand the waste and loss in terms of equipment optimization, and point towards improvement initiatives that can impact the bottom line.
