Navistar: Supply Management

The assembly supervisor at Navistar faces a critical supply problem; one that not only affects the bottom line but more importantly the customer. This case requires a student to determine what is and is not important, to think creatively about how to use the information provided, and to formulate a recommendation with respect to solving the current supply problem. The student must review: (1) a process flow chart in detail, (2) numerical data with respect to costs and frequency of specific causes for trim shortages, and (3) a number of identified causes for the supply problem. Navistar must look at value added activities, its internal policies and practices, storage of materials, a Just-In-Time inventory system that may be too tight, and communication difficulties that arise when last minute design changes occur.
