This evolution has placed to the center of the attention the supplier, transforming it in an element base for the attainment of the competitive advantage and for this reason it is necessary to establish relationships of mutual confidence, to characterize the collaboration areas and to define contracts that can guarantee to both the maintenance of the competitiveness in the time.
The immediate consequences of this new vision are:

• lessening of the total supplyes
• greater exchange of information between customer and supplier
• greater vicinity
• process of "progressive certification" of the consequent supplier to a careful selection and a continuous monitoring of the performance parameters.

• Famous 18: Strategy turned to the suppliers in which an improvement which had to the synergies of the connection is attempted.

Finally, the supplier has been only estimated on its output and therefore risks connected to not the acquaintance exist of as it can guarantee in the time such performances.
How much is not known the processes of the supplier is to "risk" as far as guarantee of quality and ability to answer to the changes in the programs.
And it is for all these reasons that are necessary to tutelarsi through emergency supplyes on such materials.
