| Situation The VP of Manufacturing is facing falling performance of orders that ship on time. Customers are looking at alternative sources, so corrective action is needed. He discovers that the primary reason for this problem is that a high volume of rework is occurring. The VP meets with various people to pinpoint the cause of the problems, but receives unsubstantiated opinions rather than factual information. Also, there is some finger pointing at vendors and material specifications as well as at the process specifications from engineering. He commissions his Production Control Manager to dig around in the systems for the problems and causes. Meanwhile, the VP holds daily meetings to review every customer order that is in process or pending, and to get reports on progress and problems. This meeting is often quite long, involves most plant managers and supervisors, materials and purchasing and QC supervisor. Everyone has to lose time that could be better spent elsewhere. Three weeks later, the PC Manager reports there is little to add to the initial findings of a lack of clarity and blame on others. There is one report of poor quality at step 2 of the manufacturing process, but not detected until inspection prior to finished goods. Rework of up to 40% of a major product line has been required. An immediate fix is implemented, with 100% inspection at several process steps, and stern warnings to supervisors to increase their vigilance, and operator awareness. Some improvement occurs, but so does an increase in direct labor and supervisory overhead that includes inspection. Because people try to cover the shortfalls with additional quantities there is an increase in material costs and some higher inventory.
Summary: Profit erosion to
achieve only partially improved quality and deliveries, with
lower plant morale. |
