Lean Lexicon, a graphical glossary for lean thinkers (Spiralé)

The Lean Enterprise Institute (LEI) is a nonprofit publishing, training, and research organization founded in 1997 to promote the principles of lean thinking in every aspect of business and across a wide range of manufacturing and service industries. A major LEI objective is to create a complete toolkit for Lean Thinkers to use in transforming traditional businesses. The lean toolkit is intended to be a dynamic and continually evolving means of sharing knowledge between Lean Thinkers. We value your feedback on the tools and encourage you to send us ) your experiences using them. We also encourage you to visit to see LEI's complete catalog of products for facilitating your lean journey and to read more about the content of our monthly workshops and the schedule of dates and locations.
