Lean can be defined as elimination of waste. In manufacturing term, it can be list as below:

• Eliminate waste in the process. Process can be anything.

Lean is different from Six Sigma. Six Sigma is all bout quality of product & services while lean is all about waste reduction. Both add plus point to business by reducing cost.
