Case Study: Will Win, Director, Quality Assurance Will Win was whistling as he walked toward his office, still feeling a bit like a stranger since he had been hired four weeks ago as director, quality assurance. All last week he had been away from the plant at an interesting seminar entitled "Quality in the 2020's" given for quality managers of manufacturing plants by the corporate training department. He was not looking forward to really digging into the quality problem at this industrial products plant employing 1967 people. Will poked his head into Rob Robert's office, his immediate subordinate, the quality control manager, and asked him how things had gone last week. Rob's muted smile and an "Oh fine" stopped Will in his tracks. He did not know Rob very well and was unsure of how to start building his relationship with him since Rob had been passed over for the promotion of Will's job - Rob's evaluation form had stated "superb technical knowledge; managerial skills lacking." Will decided to inquire a little further into what had happened Rob replied: Oh, just another typical quality snafu. We had little problem on the Gxeaser line last week (a specialized degreasing solvent packed in a spray can for the high-technology sector). A little high pressure was found on some of the cans on the second shift, but a supervisor vented them out so that we could ship them out. We met our delivery schedule! Since Will was still relatively unfamiliar with the plant and the products, he asked Rob to elaborate. Painfully, Rob continued: We've been having some trouble with the new filling equipment, and some of the cans were pressurized beyond our acceptable standard on a psi (pounds per square inch) rating scale. The production rate is still 50 percent of standard, about 14 cases per shift, and we caught it halfway into the shift. Cody Cook (the inspector for that line) picked it up. tagged the cases "Hold" and went on about his duties. When he retumed at the end of the shift to write up the rejects, Mat Mason, first-line supervisor, was by a pallet of finished goods finishing sealing up a carton of the rejected Greasex: the reject "Hold" tags had been removed. He told Cody Cook that he had heard about the high pressure from another inspector at the coffee break, had come back, taken off the tags, individually turned the cans upside down and vented every one of them in the rejected eight cartons He told Cody Cook that production planning was really pushing for the stuff and that they couldn't delay by having it sent through the rework area. He told Cody Cook that he would get on the operator to run the equipment right next time Cody Cook didn't write it up but came in about three days ago to tell me about it Oh, it happens every once in a while, and I told him to make sure to check with mantenance to make sure the filling machine was adjusted, and I saw Mat in the hall and told him that be ought to send the stuff through rework next time. Will was a bit dumbfounded at this and did not say much - he did not know if this was a "big deal" or not. When he got to his office be thought again, what Mr. Power, general manager, had said when he hired Will. He warned Will about the "lack of quality attitude" in the plant and said that Will "should try to do something about this." He had further emphasized the quality problems in the plant. "We have to improve our quality, it's costing us a lot of money. I'm sure of it, hut can't prove it! Will you have my full support in this matter, you're in charge of these quality problems. This downward quality-productivity-tumover spiral has to end!" The incident had occurred a week ago: the goods were probably out in the customer's hands by now; everyone had forgotten about it (or wanted to!); and there seemed to be more pressing problems than this for Will to spend his time on. However, this continued to nag at him. He felt like the quality department was being treated as a joke, and it also felt to him like a personal slap from manufacturing. He did not want to start a war with the production people but what could he do? He was troubled enough to cancel his appointments and spend the morning talking to a few people. After a long and very tactful morning he learned the following: A. From personnel-The operator for the filling equipment had just beentranterred from shipping two weeks ago. He had no formal training in this job but was being trained by Mat on the job, to run the equipment. When Cody Cook had tested the high pressure cans, the operator was nowhere to be found and had only learned of the rejected material from Mat after the shift was over. B. From plant maintenance - This particular piece of automated filling equipment had been purchased two years ago for use on another product. It had been switched to the Greasex line six months ago, and maintenance had 13 work orders during the last months for repairs or adjustments on it. The equipment had been adapted by plant maintenance for handling the lower viscosity Greasex, which it had not originally been designed for. This included designing a special filling head. There was no scheduled preventative maintenance for this equipment, and the parts for the sensitive filling head, replaced three times in the last six months, had to be made at a nearby machine shop. Nonstandard downtime was running at 19% of actual running times. C. From purchasing - The plastic nozzle heads for the Greasex can, recently designed by a vendor for this new product on a rush order, were often found with slight burrs on the inside rim, and this caused some trouble in fitting the top to the can. An increase in application pressure at the filling head by maintenance adjustment had solved the burr application problem or had at least "forced" the nozzle heads on despite the burrs. Purchasing said that they were going to talk to the sales representative of the nozzle supplier about this next time they came in. D. From product design and packaging - The can, designed especially for Greasex, had been contoured to allow better gripping by the user. This change, instigated by marketing research, set Greases apart from the appearance of its competitors and was seen by the designers to be "significant." There had been no test of the effects of the contoured can on filling speed or filling hydrodynamica from a high-pressured filling head. Wall had a lunch that the new design, wat acting as a venturi when being filled, but the packaging desipner thought that "unlikely." E. From the manufacturing manager-He had heard about the problem: in fact, Mat had made a joke about it, bragging about how he beat his production quota to the other foremen and shift supervisors. Mat was thought of by the manufacturing manager to be one of the "best foremen we have... he always gets his production out" His promotion papers were actually on the manufacturing manager's desk when Will dropped by. Mat was being "strongly considered" for promotion to shift supervisor. The manufacturing manager, under pressure from Mr. Power for cost improvements and reduced delivery times, sympathized with Wiil but said that the rework area would have just vented with their pressure gauges what Mat did by hand But, I'I speak with Mat about the incident. F. From Marketing - The introduction of Greasex had been rushed to beat competitors to market and a major promotional/ advertising campaign was now underway to increase consumer awareness. A deluge of orders is swamping the order-taking department and putting Greasex high on the back-order list. Production "had to turm the stuff out." Even a little off spec was tolerable because "it would be better to have it on the shelf than not there at all. Who cares if the label is a little crooked or the stuff comes out with a little too much pressure? We need market thare now in that migh-tech segment." What bothered Will the most was the safety issue of the high-pressure in the cans. He had no way of knowing how much of a hazard the high pressure was or if Mat had vented them enough to effectively reduce the hazard. The data from the can manufacturer which Rob had showed him indicated that the high pressure which the inspector had found was not in the danger area; but then again the inspector had only used a sample testing procedure to reject the eight cases. Even if he could morally accept that there was no product safety bazard, could he make sure that this never happened again? Will, skipping lunch, sat in his office and thought about the moming's events. Last week's seminar had talked about "the role of quality", "productivity and quality", "creating a new attitude", and the "quality challenge", but where had they told him what to do when this happens? He had left a very good job to come here because he thought the company was serious about the importance or quality, and he wanted a challenge. Will demanded and received salary equal to the manufacturing, marketing and R\&D directors' and reported directly to the General Manager. Yet be still did not know exactly what he should or should not do or even what he could or could not do. Provocative questions to help get you started: 1. What is wrong with the way quality is managed in this company? 2. What should be done to improve quality management
