For years, Jerry Jingle’s dairy production facilities led the state in sales volume but recent declines worry him. Customers are satisfied with his products but are troubled by the dairy’s late deliveries and incomplete orders. Production employees (not the cows) are concerned about bottlenecks in milk pasteurization and homogenization due to poor job scheduling, mix-ups in customers’ orders, and improperly labeled products. How should Jerry address the problems? What data-gathering techniques would be helpful at this early stage?
