Edward Deming
Statistical Theory
• “Students are not warned in classes nor in the books that for analytic purposes (such as to improve a process), distributions and calculations of mean, mode, standard deviation, chi-square, t-test, etc. serve no useful purpose for improvement of a process unless the data were produced in a state of statistical control.” (312)
• “A distribution (histogram) only presents accumulated history of performance of a process, nothing about its capability. As we shall learn, a process has a capability only if it is stable.” (314)
• “Statistical theory (theory of probability) as taught in the books for the theory of sampling and theory of distributions applies in the use of random numbers, but not in the experiences of life. Once statistical control is established , then a distribution exists, and is predictable.” (353)
Statistical Control (1)
Statistical Control a state of random variation, stable in the sense that the limits of variation are predictable (340):
– The process has an identity; its performance is predictable. It has a measurable, communicable capability.
– Productivity is at a maximum (costs at a minimum) under present system.
– Costs diminish as quality improves– The effects of change in the system can be measured with greater
speed and reliability. – Regularity of output
Statistical Control (2)• “Statistical control of a process is not an end in itself.
Once statistical control is established, serious work to improve quality and economy of production can commence.” (354)
• “Every problem is different from every other, and no general rule should be attempted.” (354)
• “….A production worker, when he has reached statistical control, has put into the process all that he has to offer. It is up to management to provide better uniformity in incoming materials, better uniformity in previous operations, better setting of the machine, better maintenance, change in the process, etc.” (404-405)
System
• All resources and process make up a system.
• “I find in my experience that few people in industry know what constitutes a system. Many people think of machinery and data processing when I mention system. Few of them know that recruitment, training, supervision, and aids to production workers are part of the system.” (366)
• “Test of components in stages of development can not provide (a) assurance that they will work together satisfactorily as a system in service; nor (b) the average run between failures of the system; nor (c) the type and cost of maintenance that will be required in service.” (476)
Two Causes for Failure
• Deming estimates that most troubles and most possibilities for improvement add up to proportions of around: 94% belong to the system and 6% special. (315)
• “Confusion between common causes and special causes leads to frustration of everyone, and leads to greater variability and to higher costs, exactly contrary to what is needed.” (315)
• “It is a hazard to use judgment to distinguish between special causes and common causes. Judgment has been wrong every time.” (320)
• “No amount of care or skill in workmanship can overcome fundamental faults in the system.” (315)
Special Causes – Failure due to special event or a specific person (314)
Common Causes – Failure due to faults of the system (314)
Control Charts
• Control limits, once we have achieved a fair state of statistical control, tell us what the process is, and what it will do tomorrow. (333)
• “Action line placed on a chart by judgement, not calculated….such placement of a line, as substitute for a control limit, leads to overadjustment or to underadjustment, and perpetuates whatever troubles exist.” (357)
• “Specification limits should never be shown on a control chart.” (357)
“The control chart is the process talking to us.” (333)
InspectionThe rules for minimum average total cost turn out is either:
100% inspection or 0% inspection.
• Case 1: If the cost to inspect is more than the cost to fix the average
number of defective items than you perform 0% inspection.
• Case 2: If the cost to fix the average number of defective
items is more than the cost of inspection, then you
perform 100% inspection. (409)
“The rule for no inspection does not mean to drive in the dark
with no lights. One should take a look at all incoming material,
possibly on a skip lot basis, for information and for
comparison……” (417)
Deming on Standards “Most applications of the Dodge-Romig plans of
acceptance and of Military Standard 105D are, I fear, pro forma, merely conforming to the requirements of a contract, drawn up by people without qualifications for drawing up a plan, and carried out by another group of people equally qualified. Everybody does it, so we do too. The result is increase in cost.” (431)
Deming on Improvement
“Every appalling example in this book
turned up because I was there, on the line,
on the job, trying to be helpful by looking for
sources of improvement and wrong
practices. If I had waited for them to come
for help, I’d still be waiting.” (469)
Conclusion• Identifies that measurement is critical to
developing stability and predictability
• Identifies that all measurements are meaningless unless the measurements can be repeated to identify an average
• Statistical control is when things are stable [3 StDV]
• Identifies that creating a process or system or structure that is stable is most productive
• Track and measure to develop consistency
