Today, we live in an open and global economy, where the best ideas are ruling the market. Lean thinking in business is one of those ideas of management. It is based upon the unity and speed of a workplace as a team. It also focuses upon some traditional teachings and encourages employees to follow and practice some simple but focused philosophies. In the technical and monetary side, lean business management teaches how to lower the waste and increase the customer value. Lean thinking in business is being applied by a few of the tycoons now, and it is a talk of the industry after a few books came out about this. Lean thinking is not only a business management study but more or less of a life management study also. Lean thinking can be applied in smaller business, as well as the big enterprises effectively.
