All customers are important and our goal must be to satisfy them all. However, we have observed that producers of both internally and externally consumed products consistently favor the interests of brokers over end-users and fixers. This situation is less a matter of making a conscious decision than a matter of default. Differentiation of customers into the end-user, broker and fixer roles can solve this problem. Producers may not have direct contact with the end-users.
Customers can have competing interests.
Producers may choose to satisfy certain expectations over others, based on the power of the customer. End-users always win in the long run.
