Manufacturing Terms, Buzzwords and Acronyms

As part of a consulting project I am involved in, I have created a list of acronyms and terms that are used in manufacturing and industrial automation. These are terms and acronyms from Lean/Six-Sigma, controls, electronics, business software and general corporate use. Part of the reason I did this is to ensure that everybody is on the same page when discussing different topics; everyone’s background is different and especially with acronyms, some are duplicated.

I plan to update this list regularly since it seems like a good resource. Please throw any of your own ideas in!

Part of the purpose of this list is to illustrate that words and acronyms can mean different things to different people, especially from different disciplines in the workplace. Make sure that you and the person you are communicating with are “on the same page”!
