OPC is experiencing declining profitability and Mr. John Klein, VP Finance, is trying to figure out what is the problem. He is not sure if OPC is having a product mix problem -- in which case OPC should drop the unprofitable products -- or a location problem -- in which case OPC should close a branch office.
