What is OEE?

OEE = Availability X Performance Rate X Quality Rate
Availability - Percent of scheduled production (to measure reliability) or calendar hours 24/7/365  (to measure equipment utilization), that equipment is available for production.
Note: measures the percent of time that the equipment can be used (usually total hours of 24-7-365), divided by the equipment uptime (actual production).
Performance Rate - Percent of parts produced per time frame, of maximum rate OEM rated production speed at. If OEM specification is not available, use best known production rate. 
Note: Performance efficiency is the percentage of available time that the equipment is producing product at its theoretical speed for individual products. It measures speed losses. (e.g., inefficient batching, machine jams)
Quality Rate - Percent of good sellable parts out of total parts produced per time frame.
Note: Determining the percent of the total output that is good. (i.e. all products including production, engineering, rework and scrap.) 
Example: 50% Availability (0.5) X 70% Performance Rate (0.7) X 20% Quality Reject Rate (results in 80%(0.8) acceptable) = 30%OEE (Please see www.DowntimeCentral.com/OEE_TEEP.htm for a free online calculator to practice with.) 

Why use OEE?

Overall Equipment Effectiveness (OEE) can be used to save companies from making inappropriate purchases, and help them focus on improving the performance of machinery and plant equipment they already own. OEE is used to find the greatest areas of improvement so you start with the area that will provide the greatest return on asset. The OEE formula will show how improvements inchangeovers, quality, machine reliability improvements, working through breaksand more, will affect your bottom line.

As you strive towards World Class productivity in your facility, this simple formula will make an excellent benchmarking tool. The derived OEE percentage is easy to understand and displaying this single number where all facility personnel can view it, makes for a great motivational technique. By giving your employees an easy way to see how they are doing in overall equipmentutilization, production speed, and quality, they will strive for a higher number!

How to use OEE?

Implementing the Overall Equipment Effectiveness formula in your facility can take on many different forms. It can be used as an analysis and benchmarking tool for either reliability, equipment utilization, or both. Don't let indecision on how to best use OEE become a barrier that prevents you from using it at all. Start out small if necessary, picking your bottleneck to collect the OEE metrics on. 
Once you see first hand what a valuable tool it is, you can gradually take OEE measurements on other equipment in your facility. If you work in  manufacturing , there is no substitute for going out to the shop floor and taking some rough measurements of OEE. You will be surprised by what you find!

While monitoring OEE per equipment brings focus on the equipment itself, it may not provide true cause of major costs, unless the cause is obvious. For example OEE can appear improved by actions such as purchasing oversize equipment, providing redundant supporting systems, and increasing the frequency of overhauls.
To improve your OEE percentage, you will need to use other tools and methodologies available to you, like TDC, RCA, SCADA, FTA etc. TDC is a relatively new methodology that focuses on True Downtime Cost for justification and making better management decisions.
