Supplier Reduction Regardless of one's final analysis of the single/multiple sourcing debate, it is recommended to reduce the overall supply base. If the perceived benefits outweigh the risks, after careful analysis of both short-term and long-term needs, a single source may be appropriate. However, for operations that would be financially damaged when a supply stoppage occurs, then the use or development of a second source is wise. Benton, W. C..
