"Thoughts on quality from one of the boys: Abe"
Back in the late 1970's, Vanderbilt had a summer internship program with a lot of the big fortune 500 companies as well as smaller companies.
I remember talking to a student about his summer experience when he worked at one of General Motors manufacturing plants in which they were assembling cars.
He finished the summer with the idea he would never buy or own a GM product and went on to say that they were using rubber mallets to solve a quality problem.
There was a slight interference issue with two of the stamping dies. Instead of correcting a problem in the supply chain, the solution was to issue rubber mallets
on the assembly line and institutionalized the problem into the production process.
I'm not taking about using a rubber mallet as a production tool, which is OK. I'm taking about using the rubber mallet as a solution to a quality problem.
Metaphorically, a rubber mallet solution is used a lot to solve quality in the United States. Too frequently, companies talk the talk and then follow the same 'ol rubber mallet solution. Let's think about that, what did GM lose thirty years ago by giving that student--that impression of quality--within one of America's venerable giants in American industry, and more importantly, what did America lose by sending that impression back to an engineering school full of eager and talented young minds? We haven't lost our manufacturing based solely on this anecdotal parable; obviously our loss of manufacturing infrastructure has to do with global economic forces that have developed, but a lot of it is because we have taken our eyes off of the Golden Goose, i.e., manufacturing, and the process of product improvement within the manufacturing process.
"A statistical approach to quality"
Quality is approached many difference ways. One of them is the Edwards Deming
solution, which is a statistical approach to quality. The Japanese auto manufacturers embraced his concept and they made huge inroads to the automotive market in the 1980's.
Regarding the summer experience thirty years ago, the Japanese would have implemented statistical controls which would have identified the problem and developed the appropriate feedback
through the supply chain. The resultant would have been parts meeting specifications subject to statistical verification. I think our company does this on a more tactile level.
We are constantly monitoring the raw materials; we inspect the glass, the locks, the balances that we use everyday; and we check the finished product. We report bad quality up
the supply chain, and we work our relationships in the supply chain for continuous improvement.
My brother, Zeke,
is a stickler for this. He constantly does an informal statistical sampling everyday. He is walking the plant and asking the supervisors if they have any problems. He is
physically handling the parts themselves as they are used in the manufacturing process. (And thereby doing an informal statistical sampling.)
I'm trying to accomplish a lot with this short treatise on quality, one of which is to let our customers and potential customers get to know us better. I'm hoping that you can get a flavor of the culture of our company. I only hope that my brothers don't mind my ramblings too much.)
"A psychiatric approach to quality"
I want to make a rather unique comparison between alcoholism and quality: the connection between quality and the inherent imperfections of people. Just
to set the tone, I'd like to say I'm not perfect, our employees aren't perfect and our suppliers are not perfect. Within that set of conditions we are trying to achieve
zero defects. Statistically that is impossible. At best we can get 99.xxx% correct windows, which means that we have a quality problem event 0.y% (1-99.xxx%) of the time.
Potentially pretty good, but we can also do potentially better. Herein lies the issue. If our quality defect percentage is low, how do we cut this defect rate in half again?
Ok, so how can you make a connection to 0.y% quality defects and alcoholism? It's easy, first and foremost is that you can not improve your quality if you deny there is a problem.
If you say the 0.y% is not a problem, then your in denial of a problem. Like an alcoholic, GM was in denial of it's problems for years; they denied it to their dealers--they
denied it to their paying customer. Their problem was much more than the marginal increases in quality that I am talking about, but you can use it as a case study on how to get better.
Secondly and simply, once you have identified the quality problem you have to take it one day at a time once an action plan has been established.
There are parallels to the psychiatric diagnosis process. The manufacturing team has to monitor the process after the decision has been made to solve an intrinsic quality issue.
Things change, what you thought you knew about the process might not be true. Finally even if you have a solution to a problem--you can fail each and every day.
I've got an NFL analogy coming later. As a preamble to that, you have to practice fundamentals each and every day.
You have to realize that people are fallible by nature. And you have to realize that you cannot get blood out of a turnip. You have to work with people. You have to build relationships with your suppliers; you have to build relationships with your employees to build a trust in the management. The company has to prove to the employees that their thoughts matter, both personally and professionally. They have to be a member of the team. And they have to know that they will not be victims of "kill the messenger" syndrome. If you can do that, then they will help you monitor the quality process and they will give you suggestions on how to do it better.
The design approach to quality
Quality to be considered in the design stage on the front end of the product life cycle. Many companies do not take this under consideration in the fenestration industry. Most do not have the software or design capabilities to even make decisions on such issues. The vast majority of window companies buy from a uPVC profile extruder. The extruders provide a series of double hungs, single hungs, and picture and market their designs to window manufactures that do not have the capability to extruder or design there own product. At MGM we have the ability to design our product; extrude our own profile (i.e., the vinyl lineals which are used to fabricate a window); manufacture our product and test our own product. In the process of design we have built relationships with companies that are also innovators. As an example our impact version of our 8010 series double hung (8080 series) has a slide latch that is nested in the sash aluminum reinforcement. Most window companies have taken a band-aid approach to the solution and have a top-mounted latch and the slide bolt is only held in place by screws in the latch housing. Our design is much stronger, and, consequently is better quality. As a final example of designing quality into a part, I would like to discuss our 8010 series sill. This product line has three features that you will not find on any other vinyl window system in the country:
•A corner key with an integral 1/4" shim. This will automatically shim the window in the opening which will eliminate crowning of the sill as a result of a crown in the framing on which the window sits.
•An aluminum nail fin. This will eliminate most, if not all, damage during the handling of the window during shipping. It will also eliminate crowning described above, and it will make the installation more rigid.
•A removable sill tower. This allows the builder to replace the sill tower if it gets damaged during construction. This is another feature that is exclusive to our vinyl window systems.
Without quality being designed into the part there is no statistical process control, or Psychiatric approach in the world that will create superior quality. At MGM we take a holistic approach and apply the techniques that are discussed at length. I am sorry for the long rendition, but if you want only lip service, then buy someone else's product. If you really want quality, then give us a close look: if you can find a better window, buy it.
"The definition of a Champion"
Each and every year we have the NFL playoffs which leads to a new Super Bowl champion to be christened. I bet you money, at some point in the battles some team member
on the eventual winner will make a mistake. Somebody will miss a coverage; somebody will miss a block; somebody will be penalized for holding an opponent; perhaps there will be a
miscommunication between the huddle and the sideline. Something will happen to the eventual champion. Notice I said champion and not winner. Believe it or not,
somebody could win that game and not be a champion in my mind. Champions manage their mistakes and take corrective action. Champions are the ones that return to
the Super Bowl because they have worked on the quality process (fundamentals). Champions acknowledge their errors and make sure the process is changed so that problems don't occur
systematically. The playoff games are fast paced, things are going to change by the minute and the second. Players and coaches are going to have to monitor that situation on a real-time
basis and adapt. Manufacturing anything is like that.
(As a side note, if Champions get blamed for an infraction that they did not do, then that does not mean they will like to accept a penalty for an infraction that was caused by others. That's an issue with customer relations, which is another issue. However, if a customer pays their bills, then I think a Champion will work with the customer even if the infraction was not caused by the champion. But that's moving into the concept of partnership--which we also know very well. )
Back to football, if one team is pounding it up the middle, it would not be a good strategy to stay in nickel coverage.
That would be analogous to the assembly line worker just pounding with the same rubber mallet, or as Elmer Fudd might say: mauwit.
The solution is not to continue with the rubber "mauwit", it is monitoring the situation and taking corrective action. In the football analogy, it's changing the strategy and getting that message
to the players.
My real passion, and our teams passion, is windows and doors. It's worth saying again: to get that last marginal benefit to the quality management process, our company's team has prepared the organization to succeed by following the Alcoholics Anonymous credo--we take it one day at a time. We monitor quality everyday. We walk the plant floor: we walk the walk. And last but not least, we design quality into our window system!
This is what it takes to get your quality level from 0.01% defect rate to a .005% defect rate. Leave your mauwit at home!!
