Every year, federal agencies spend over $500 billion to buy a wide variety of products and services, ranging from cutting-edge military aircraft to common office supplies. Supplier performance and sourcing strategies within the Air Force are distinctively complex due to the wide array of weapon systems and limited number of suppliers available within the marketplace. Academics and industry experts agree that the foundation for strong buyer-supplier relationships is a means to achieving superior performance. However, this dynamic can yield varying results when there are a limited number of suppliers available. One of the problems which emerges from the critical need of spare parts is that the delinquent rates increase as the number of approved suppliers increases. Conversely, although delinquent rates tend to be improved when there are two or less suppliers, the Air Force is highly susceptible to disruptions in the event of single sourcing failures. Therefore, the Air Force needs to optimize its supply base by considering supply risks within relevant laws and regulations.
