Deming 14 points

Sep 4 2012

Rereading Deming’s 14 points

The richest discussion in this blog to date, on Deming versus Drucker,  is all about point 11.b. from the list of 14 points that is the best known legacy of Deming’s 1986 book  Out of the Crisis. But what are his actual 14 points, and who are they intended for? Let us start with Deming’s own summary, from p. 23 of the book:

  1. Create constancy of purpose toward improvement of product and service, with the aim to become competitive, stay in business and to provide jobs.
  2. Adopt the new philosophy. We are in a new economic age. Western management must awaken to the challenge, must learn their responsibilities, and take on leadership for change.
  3. Cease dependence on inspection to achieve quality. Eliminate the need for massive inspection by building quality into the product in the first place.
  4. End the practice of awarding business on the basis of a price tag. Instead, minimize total cost. Move towards a single supplier for any one item, on a long-term relationship of loyalty and trust.
  5. Improve constantly and forever the system of production and service, to improve quality and productivity, and thus constantly decrease costs.
  6. Institute training on the job.
  7. Institute leadership (see Point 12 and Ch. 8 of Out of the Crisis). The aim of supervision should be to help people and machines and gadgets do a better job. Supervision of management is in need of overhaul, as well as supervision of production workers.
  8. Drive out fear, so that everyone may work effectively for the company. (See Ch. 3 of Out of the Crisis)
  9. Break down barriers between departments. People in research, design, sales, and production must work as a team, in order to foresee problems of production and usage that may be encountered with the product or service.
  10. Eliminate slogans, exhortations, and targets for the work force asking for zero defects and new levels of productivity. Such exhortations only create adversarial relationships, as the bulk of the causes of low quality and low productivity belong to the system and thus lie beyond the power of the work force.
  11. a. Eliminate work standards (quotas) on the factory floor. Substitute with leadership.
    b. Eliminate management by objective. Eliminate management by numbers and numerical goals. Instead substitute with leadership.
  12. a. Remove barriers that rob the hourly worker of his right to pride of workmanship. The responsibility of supervisors must be changed from sheer numbers to quality.
    b. Remove barriers that rob people in management and in engineering of their right to pride of workmanship. This means, inter alia, abolishment of the annual or merit rating and of management by objectives (See Ch. 3 of Out of the Crisis).
  13. Institute a vigorous program of education and self-improvement.
  14. Put everybody in the company to work to accomplish the transformation. The transformation is everybody’s job.

On the face of it, this is an odd mixture of actionable recommendations — like “a single supplier for any one item” — with generalities like “adopt the new philosophy,” and expressions like “a vigorous program” that don’t meet Deming’s own criteria for an operational definition (See Ch. 9 of Out of the Crisis). As a consequence, the summary is not sufficient to understand what Deming actually meant.

Deming elaborates on each point in the remainder of Ch. 2 but, contrary to what the reader might expect, the whole book is not organized around the 14 points. About 20 years after Deming, in  The Toyota Way, Liker also identified 14 principles, and then devoted a chapter to each, which gives the reader a sense of structure that is missing in Deming’s book.

On the other hand, what comes out of Deming’s book is a sense of urgency. He was in his eighties when he wrote it,  a celebrated figure in Japan but obscure in the US until 1980 when NBC aired its documentary If Japan Can… Why Can’t We?  In the early 1980s, industries like steel, cars, semiconductors, and consumer electronics in the US were facing formidable competition from Japan, but most American managers credited it to long working hours for low wages and unfair trade practices. The idea that there was anything to learn from Japan was a hard sell, and only a few, well-informed individuals like Deming knew that it was the case.

Deming obviously felt he had much to say to American management that was essential to future competitiveness, and little time to say it. He couldn’t afford to sugarcoat his message and didn’t have the leisure to organize it into a neat theory. His readers would just have to handle the truth and organize the parts themselves.

Deming is blunt and direct, and backs up his assertions with examples. He is often prophetic but, in hindsight from 2012, occasionally off the mark. He correctly predicted that Japan would achieve a standard of living on a par with the US and Western Europe, but he perceived the breakup of the AT&T monopoly as “wrecking our system of telephone communication” (p.152), which works pretty well for a wreck.

One criticism I have for all lists of 14 points, whether from Woodrow Wilson, Deming, or Liker, is that they are impossible to remember. They should have boiled their lists down to 7 or even 5 points. I will have more detailed comments on each point in forthcoming posts.

Blog passes 40,000 views

This blog crossed the 40,000 cumulative views mark yesterday, after 9 months of existence.

It reminds me of Stephen Colbert’s enthusiastic announcement that Romney’s horse Rafalca scored 73 points in the Olympics.

His next sentence was: “Is that good?”

I am in the same predicament.

Deming versus Drucker

Aug 26 2012

Deming’s Point 11.b of 14 – Deming versus Drucker

In his 14 points, by saying “Eliminate management by objective. Eliminate management by numbers and numerical goals,” Deming directly attacks Peter Drucker, the most revered guru of American management and creator of Management-By-Objectives (MBO). By the time Deming contradicted him, Drucker was an American institution, as sacred as the constitution. Drucker has published a new book every two to three years from 1939 to 2005 and contributed more than 30 articles to the Harvard Business Review. He received numerous awards from several governments, including the US Presidential Medal of Freedom, and has streets and a business school named after him.

In the Lean world, MBO has been replaced by Hoshin Planning, which is subtly but radically different. Drucker’s influence in the US remains so strong, however, that my favorite book on Hoshin Planning, Pascal Dennis’s Getting the Right Things Done, actually pays homage to him. The title itself is Drucker’s definition of effectiveness and, inside, Dennis presents Hoshin Planning as a refinement of MBO. It is still easier today to get through to an audience of American managers by standing on Drucker’s shoulders than by debunking him.

But Deming was in his eighties when he wrote his 14 points, his success in Japan had finally given him an audience in the US, and he must have known that he was running out of time to make his points. He thought MBO was a bad idea  and he would not pussyfoot. 15 years later, Drucker himself came around to the same point of view and recognized that MBO had failed. What did Deming find wrong with it?

In The Practice of Management (1954), Drucker repeatedly asserts that it is essential for managers to have quantitative objectives to work towards. They should set these objectives themselves, consistent with the objectives of the business as a whole. But Drucker is short on how this could actually be done, how you identify proper metrics, how you set targets for each metric, and how you go about reaching these targets. It is not an accidental omission. In  Drucker’s world, managers can find the answers themselves. It is part of their job, and they are supposed to have the requisite talents.

Instead,  Deming sees arbitrary objectives, unrelated to the purpose of the business, set without any plan on how to achieve them or even a means of taking accurate measurements. Deming sees MBO as “an attempt to manage without knowledge of what to do.” The managers focus on outcomes without looking into the processes that produce them. They end up gaming metrics rather than improving  processes, and playing management whack-a-mole.

About managing by numbers, Deming notes that performance evaluations of groups or individuals fail to  differentiate between fluctuations and outliers. Whether you measure quantities produced or units sold, there will always be a ranking, but top performance only indicates a difference in effort or talent if it is high enough to be an outlier. Otherwise, it would be just as meaningful to rank people based on the number of heads in 50 coin tosses.

Deming makes the case that fluctuations should never be the basis for management decisions. If you sell a product through three dealers of equal talent and resources, with territories of equal sales potential, you will still observe differences in results that will enable you to rank the dealers, even though these differences are just the luck of the draw for this particular period.

What Deming does not go into is what happens when you repeat this kind of ranking over a sequence of periods. If the first period was a fair competition, the following are not, as the top performing dealer starts receiving preferential treatment, such as an award to post in the show room, priority access to new products and marketing materials, and special training in sales or customer support. All of these advantages make it more likely that the ranking will be the same in the next period, with a larger gap. Revisiting Pareto shows how iterations of a pure game of luck can lead to the top 20% of the players holding 80% of the chips when the outcome of each round determines the probabilities of success in the next round.

If one of the dealers sold not 5% more but three times as much as the other two, it would be difficult to explain it away as a fluctuation or a fluke. It would be most likely due to the use of a different and more effective approach, which would warrant special treatment.

What is perhaps most remarkable about the story of MBO is that its poor performance has made no dent in Drucker’s reputation as a business thinker, and that many companies continue to use it.

Taking a Stand at Work

See on Scoop.it – lean manufacturing

The notion that production work should be done standing has been controversial in Lean implementations, and resisted in particular by experts in ergonomics. Now several health researchers are saying that sitting is about as healthy for humans as smoking.

This article is about Anup Kanodia, from Ohio State’s Center for Personalized Health Care, and his recommendation to reorganize offices for stand-up work. See also NASA’s Joan Vernikos’s Sitting Kills Moving Heals.
