CMMS-EAM-OEE-TPM An alphabet cocktail
– An alphabet cocktail for manufacturing, maintenance and production
The goal of any manufacturer and production organization is fairly simple, get the most out of your equipment (assets), while producing quality goods. So how and where do each of the ingredients of the alphabet cocktail come into play?
So now you are tracking everything you need to know about your equipment (asset) with a CMMS/EAM solution or are you? No the next key ingredient in the alphabet cocktail is OEE (Overall Equipment Effectiveness). It is one thing to fix your equipment when it breaks down or better yet try to prevent those breakdowns with an aggressive preventive maintenance program. Let’s remember one of the key goals of manufacturing and production is to get the most out of your equipment (assets). This is where an OEE System comes into play.
The history of OEE can be traced back to metrics developed by Seiichi Nakajima in Japan during the 1960s to evaluate how effectively a manufacturing operation is utilized. OEE is based on availability, performance and quality rate.
Measurement of Overall Equipment Effectiveness (OEE), is becoming widely accepted as an overall measure of manufacturing effectiveness. However, when correctly applied, OEE is much more than a management benchmark. It is a powerful troubleshooting tool that identifies areas for improvement at the functional level.
It is important to remember that OEE is part of an overall improvement program and NOT just another KPI to measure. OEE is at its best when it is focused on one single asset or a synchronized line. Of course there are numerous studies of what a “World Class” OEE number is for a manufacturer or production operation. These “World Class” numbers should not be used as a benchmark. Remember OEE is about attaining improvements. A “World Class” continuous production operation might have an OEE number in the 90’s, but if you take your operation from the low 40’s up to the 60’s you have achieved a 50% improvement!
What can your maintenance program and your CMMS/EAM do to contribute to improving OEE’s three keys of availability, performance and quality?
