31 Jan The Lean Glossary
Embarking on a lean journey bodes well for the future success of your manufacturing operation, although it can feel like entering a minefield of terminology. You’ll soon discover that a little advice can go a long way.
As leading providers of integrated OEE software, Idhammar recognises the importance of complete visibility, in terms of both production performance and understanding OEE concepts, in order to drive a programme of continuous improvement.
So, we’ve put together The Lean Glossary of common terms and phrases used in the world of lean manufacturing, OEE and Continuous Improvement, to help lessen the confusion and improve your understanding of all things lean. You can’t go wrong!
