Deming’s 3rd point is the first to mention quality, and it is specific, even if its implementation is sometimes a tall order. Its complete statement is as follows:
“Cease dependence on inspection to achieve quality. Eliminate the need for massive inspection by building quality into the product in the first place.”
The idea that quality should be built into the design of the products and into the processes to manufacture them has come to be generally accepted in the past 30 years, and implemented in many industries. You never hear anyone arguing against it. At the same time, final inspection and test has never completely disappeared, even in the car industry. Engines, for example, are all tested before moving on to assembly, even at the best manufacturers, and body paint is visually inspected by people.
In the details he gives about this point, Deming acknowledges that there are exceptions where no one knows how to build quality into the process. In particular, he mentions integrated circuits. It is still true in 2012, and the economic importance of this “exception” has grown in the past 30 years. There are also other, older technology products for which there is no alternative to sorting the output. Lead shot, for example, is produced by pouring molten lead into a sieve, collecting the solidified drops, sorting the ones that are sufficiently round based on their ability to roll down chutes, and recycling the others.
Oddly, Deming includes “calculations and other paperwork” in a bank among the activities for which mistakes are “inevitable but intolerable.” Today, an individual using on-line bill-pay to settle a utility bill expects that the exact amounts will be properly debited and credited without human intervention. If, on the other hand, you are occasionally transferring $300K from Russia to the US, you can expect humans to validate the transaction.
At least in Out of the Crisis, Deming does not distinguish between inspection and testing. Inspection is a manual process, subject to human error and to dilution of responsibility when a product is subject to multiple inspections, which is why he describes it as ineffective as a filter for defectives. At the end of their process, however, integrated circuits are not inspected by humans but tested on automatic test equipment that, if properly calibrated, provides consistent results. The relevance of these results depends on the human process of programming the test equipment; the productivity of test operations, on the sequencing of the tests.
Because inspection and test is perceived as “non-value added,” it has a bad odor in the Lean community, and is ignored in its literature. Today, however, it is something we have to do, and we might as well do it well. Deming discusses it in Chapter 15 of Out of the Crisis; I, in Chapter 16 of Lean Assembly .

In yet another examples of journalistic innumeracy, this article confuses a quantity, manufacturing activity, with its variation, growth.
The title “Manufacturing growth is down for third straight month,” leads you to believe it says that growth is lower but activity is still growing.
The first sentence confirms this: “Manufacturing growth in August remained as it had been in the previous two months—sluggish.” Sluggish does not mean negative.
But the next paragraph tells you that manufacturing activity had actually been contracting, not growing: “ISM’s index used to measure manufacturing activity, was 49.6 in August, which is 0.2 percentage points below July and 0.1 percent lower than June. A reading of 50 or higher indicates growth is occurring.”

Response to a question in the IndustryWeek manufacturing network on LinkedIn:
For metrics of quality itself, see Metrics in Lean- Part 2 , but you specifically asked about the productivity of your Quality Assurance (QA) department, meaning that you are interested in its efficiency rather than its effectiveness. It is a legitimate concern, as long as you don’t pursue efficiency at the expense of effectiveness, which is common but not in the best interest of the organization as a whole.

Deming’s Point 6 of 14 – Institute Training on the Job
Deming’s full, terse statement of his 6th Point is as follows:
“Institute” is stronger language that just “implement.” It is not just about making something happen, but turning it into an institution. In the language of the 1980s, “on-the-job training” was synonymous with “sink or swim”: as a rookie engineer, you were given projects, and it was up to you to figure out how to carry them out. Given that you had had your fill of classes in college, you didn’t mind. Production line operators received some mandatory orientations on things like safety gears, but relied on colleagues to figure out how to do their work. So, what was Deming talking about?
Deming’s elaboration on Point 6 actually drops the “on-the-job” and is entitled just “Institute training.” In it, explains that it is about “the foundations of training for the management and for new employees,” as opposed to continuing education. Regarding management, he points out that Japanese managers “start their careers with a long internship (4 to 12 years) on the factory floor and in other duties in the company,” implying both that it is systematic in Japan, and not done anywhere else. I once worked with a Purchasing manager in a major Japanese company who had five spent years in Design Engineering (See Point 4), and this was part of a number of rotations preparing him for senior management positions. However, it was not systematic, in that not all professional employees went through this process.
This practice is also predicated on long-term, committed employer-employee relationships. It trains managers who know in depth how the company works and have personal ties to many of its departments, but are not necessarily at the top level of expertise in any of their specialties, and it does more to enhance their value to the company than their marketability outside of it. Similar practices are also found outside of Japan, in companies like Boeing, GM, or Unilever, for young employees identified as having “executive potential” (See Alternatives to Rank-and-Yank in Evaluating People). In Italy, I had the opportunity to work with a production supervisor in a frozen foods plant who was a young German engineer in such a program. The parameters and the management of these programs matter. They may degenerate, for example, if the time spent in each position is too short and if participants are rewarded for not making waves.
Here again, Deming is at odds with Drucker. The rotation of managers to be seasoned in the specifics of the company’s business before being promoted is contrary to Drucker’s concept of a professional manager who can run any business, and more in line with the practices of the military. When, at the end of The Practice of Management, Drucker discusses the preparation of tomorrow’s managers, which he sees as a combination of a “liberal education for use,” centered on classics and on a “basic understanding of science and scientific method,” supplemented by continuing education in advanced techniques of management. In his view, managers need to respect technical workmanship in the activity of the company, but they don’t need to possess this workmanship themselves, and their generic management skills are transferable across industries. At Apple, Steve Jobs would probably have agreed with Deming; John Sculley, with Drucker.
Deming says little on how shop floor operators should actually be trained, and makes no reference to Training-Within-Industry (TWI), a program we would have expected him to be familiar with as a development that was contemporary to his own work in World War II, but a Google search for “Deming +TWI” does not match any document. He bemoans companies’ failure to use people’s abilities but does not explain how training, on the job or otherwise, can remedy this.
Deming also says that training should be focused on the customer’s needs, which, influenced by TQM, we may interpret as meaning the next process. When Deming writes “customer,” however, he does not mean it metaphorically but literally. He is actually thinking of the real customer, the one who pays and has the option to buy elsewhere. In other words, training must relate the work done at any workstation to the experience of the end user of the finished product. The farther upstream from final assembly, the more remote the connection and the more challenging it is to communicate, but the more understanding an operator has of the effect of the work, the stronger the motivation to do it well.
Even in the best companies today, much of the initial training of operators is done off-line rather than on the job. The basic employee orientation on company procedures or personal protection equipment is, of course, done offline, but so is a major part of the work itself. Machinists learn the basics of CNC turning with tabletop lathes that carve wax cylinders before moving on to actual machines, and assembly teams learn the basics of the Kanban system through simulation games.
