  • Box on Quality

    Dr. George Box is not as well known in the general management community as his ideas merit (in my biased opinion – photo of Bill Hunter and George Box). He is well know in the statistics field as one of the leading statistical minds. Box on Quality is an excellent book that gathers his essays from his 65th to 80th year.

  • Management Training Program

    So I said to the Toyota executive, “You’ve only got two or three suppliers per category, and you never take bids. How do you know you aren’t being ripped off?” So this guy, who was around 60, gives me an incredibly frosty look and says, “Because I know everything.” Everything? “That’s my job,” he says.

    Reading “Because I know everything” brings to mind an arrogant blowhard to many in America (I think). Probably because most who would say that, are arrogant blowhards. But when someone has worked (a Toyota executive or a baker) for 40+ years in the same area those words can have quite a different meaning than a 31 year old MBA working in his third industry. Managing with constancy of purpose and long term thinking can make a big difference.

  • Government Lean Six Sigma

    Once the political decision has been made to eradicate polio then that desire can be carried out – and politics really has little impact. Other examples are not as simple. A political decision to eliminate AIDS runs into political controversies in selecting the best strategies to accomplish the goal.

    A desire to eliminate hunger, poverty or homelessness run into differing opinions on how those problems should be addressed. I can’t imagine any politician against the elimination of those problems. However, many politicians will be against various tactics to accomplish those goals.

    Political decisions have management components but arguing about the poor management effectiveness of political decisions is a bit too advanced for our current capability, I believe. It seems silly for a government to subsidize mansions being built in hazardous areas where insurers would not insure construction, but for political reasons it continues. It seems silly to have the political leadership prohibit the government from negotiating lower drug costs from suppliers, but they do.

  • Managing Innovation

    You manage processes such as thinking up a new way to use computer technology differently than you manage a process to manufacture tires. But the idea that you don't manage and improve the process just because the process seems discontinuous is a mistake.

  • Innovation and Research and Development

    Innovation can be related to productivity improvement or it can be completely unrelated. A company could innovate with an ideas like the remote control for televisions (or microlending or air bags). That innovation may not contribute in any way to manufacturing televisions more productively.

    Other innovation may be related to improving the productivity alone and add no additional functionality to the customer. Many innovations will provide a combination of both benefits. Both innovation and productivity improvement are important.

  • Eliminating Complexity from Work

    as much as half of the activities of about sixty people had been to set up and take down jobs, expedite, move material, count material, and do other tasks that were unnecessary in the new process.

    Tim Fuller's article discusses how much inneficiency was removed from the process by adopting single piece flow in 1985.  How long did it take for management practice to understand this?  Certainly this understanding wasn't widespred in 2005.  I am not even sure it if it is widely understood and systems have been designed or redesigned with this knowledge in 2017.

  • Process Improvement of the Order Fulfillment Process

    Shipping an international order now takes about 35 seconds, down from 3 minutes, and can be done by anyone, whether or not they have SQL and Mail Merge skills. Domestic orders are even faster since they don’t need customs forms. Most of all, it’s all really fun.

  • Public Sector Management Using Deming's Ideas

    Madison’s quality improvement efforts began after then-Mayor James F. Sensenbrenner and his staff were exposed to the teaching of W. Edwards Deming in 1983. A pilot project at the motor equipment division made substantial improvements in prioritizing repairs, improving communications with customers, reducing steps in the inventory purchasing process and, ultimately, reducing vehicle down time, all of which saved money and improved service at the same time. Based on the success of the pilot, it was decided to expand the philosophy throughout city government.

  • Agility vs. Six Sigma

    Some people dislike the idea of managing processes. In my experience they then invent the idea that slow, boring process improvement is an alternative to innovation. That is just wrong. Process improvement should be part of a well run system, as should innovation. Deming, who many believe focused only process improvement, knew the importance of both. See several of Deming’s ideas on innovation.

  • Zero Defects

    I do not believe you succeed by declaring your goal to be zero defects. You succeed by creating a culture of never ending improvement, of customer focus, of fact based decision making, of learning, of “empowerment”…

    Part of that improvement is reducing variation, reducing defects, implementing smart new mistake proofing but innovation is too. Effectively zero defects is not really achievable in most cases. Defects are largely a matter of definition. As performance improves expectations will often rise. When you eliminate anything you would have called a defect years ago, standards are higher and things that would not have been called defects are no longer acceptable. At some point the system process advances to such a level where zero defects is possible in some cases but in many (say medical care, air transportation, education, computer software, restaurants, government, management consulting, civil engineering, legal services…) I really think it is basically impossible.

  • Change is not Improvement

    We trained hard… but it seemed that every time we were beginning to form up into teams we would be reorganized. I was to learn later in life that we tend to meet any new situation by reorganizing; and a wonderful method it can be for creating the illusion of progress while producing confusion; inefficiency, and demoralization.

    These lines, from the Satyricon of Petronius written 2,000 years ago…*

  • Is Made in the USA Back In Vogue? (2006)

    This example provides more evidence of the benefits of "lean manufacturing," though it seems they are getting only a few benefits (reduction of waste, faster resupply of "hot items") and they may well not know about <a href="http://curiouscat.com/management/leanthinking.cfm">lean thinking</a>.  By studying and applying lean ideas they should be able to reduce the 45 day turn-around time.  Perhaps they should read the Fashion Incubator blog...

  • Using Design of Experiments

    Design of Experiments can seem complicated but at the core it is fairly simple and powerful. By applying the proper techniques it allows you to gage the effect of several variables and, very importantly, the interactions of those variables with a small number of experiments (or tests or pilots).

    George Box is a wonderful author (and friend) who can write for mangers who are not knowledgeable about statistics and statisticians. Statistics for Discovery does a good job of explaining how organizations should use experiments to improve.

  • Quality and Costs

    Deming explained that increasing quality decreases costs. Page 3 of Out of the Crisis: Improve Quality –> Costs decrease because of less rework, fewer mistakes, fewer delays…

    Like most models this does not explain everything. Achieving some quality desires does cost more. And the article examines how to look at the issue of cost reduction in health care, where the view that higher quality costs more persists to a larger extent than elsewhere. There is significant room in health care for adopting improvement that will improve quality and reduce costs because the systems are so poorly designed they are both increasing costs and decreasing quality over what could be achieved.

  • Lean National Health System

    This is an example of focusing on improving the system which will then result in improved measures (cost savings for example). This systems approach contrasts with cutting costs by cutting every budget by 5% across the board which often fails. Without improvements in the system reducing budgets just reduces capability.
