Pronghorn Company manufactures automobile components for the worldwide market. The company has three large production facilities in Virginia, New Jersey, and California, which have been operating for many years. Brett Harker, vice president of production, believes it is time to upgrade operations by implementing computer-integrated manufacturing (CIM) at one of the plants.
