I believe this statement is true...................

true and good reply from Mr. Vinod 

Maybe true, but where is the sold relation between lean management and one supplier per item.

Lean management is an approach to running an organization that supports the concept of continuous improvement, a long-term approach to work that systematically seeks to achieve small, incremental changes in processes in order to improve efficiency and quality.

Guiding principles for lean management include:

1. Defining value from the standpoint of the end customer.
2. Identifying each step in a business process and eliminating those steps that do not create value.
3. Making the value-creating steps occur in tight sequence.
4. Repeating the first three steps on a continuous basis until all waste has been eliminated.

Nowhere does it say or mean that only one supplier per item should be kept.
