    http://www.brunel.ac.uk/research/qi/spc/home.html
    
    Extractions: Universally, businesses and industries use mathematics and statistical measurements to solve problems. There is an increasing demand for managers and workers who understand and are able to apply Statistical Process Control methods. While working at Bell Telephone Laboratories in the 1920's, Walter Shewhart developed a process using probability and variation theorems to increase the level of quality in the manufacturing process. He developed a method, called a control chart, of monitoring each process. By careful analysis of these charts, workers could detect and prevent many defects. More emphasis was put on specialization of areas. Though most companies continued with mass inspection, some companies changed, and gave more control to the worker. The need for mass inspection was eliminated. Each worker inspected his or her process and made changes as needed. This method gave workers better control over their process so that time, energy, and money was saved by eliminating scrap. Because the workers were given more responsibility and power, they took more pride in their work.

66. Quality For Business Reducing Variability
    walter shewhart. The idea of control as applied to variation was developedin the 1920s by walter shewhart in the Bell Telephone Laboratories.  
    http://www.thedecalogue.com/Papers/thevoice.htm
    
    Extractions: The aim of this article is to try and clarify what the prerequisites are for building Quality (with a capital Q). The first step is to understand what variation is. Once we have an understanding, we can recognize how the two approaches to variation – conformance to specifications versus consistency of processes – are irreconcilable. Quality means ( ) “On Target with Minimum Variance.” Walter Shewhart At the end of the eighteenth century, the fundamental problem the industrial revolution had to deal with was producing identical parts. This problem was (and still is) the source of enormous difficulties. We all know that no two things are exactly alike, so manufacturers had to settle for making things that were “similar enough”. The concept of “specification” thus arose from the need to define how similar two things had to be so they could be categorized as “good” (within specs) and “bad” (out of specs and therefore to be scrapped.) This distinction did not help manufacturers to make more parts within specs, nor did it help them understand the reason for non-conformities. The only thing this method allowed them to do was separate the wheat from the chaff at the end of the production line. The production process was more or less what you can see in figure 1.

    Extractions: by Corinne N. Johnson, editorial assistant The plan-do-check-act (PDCA) cycle is a well-known model for continual process improvement (CPI). It teaches organizations to plan an action, do it, check to see how it conforms to the plan and act on what has been learned. The PDCA cycle is made up of four steps for improvement or change ( see Figure 1) 1. Plan: Recognize an opportunity, and plan the change. 2. Do: Test the change. 3. Check: Review the test, analyze the results and identify learnings. 4. Act: Take action based on what you learned in the check step. If the change was successful, incorporate the learnings from the test into wider changes. If not, go through the cycle again with a different plan. A brief history The PDCA cycle is also known by two other names, the Shewhart cycle and the Deming cycle.

Pre-1600 If the early 1800s were the ``golden age'' of statistical graphics and thematic cartography, the early 1900s could be called the ``modern dark ages'' of visualization [ There were few graphical innovations, and, by the mid-1930s, the enthusiasm for visualization which characterized the late 1800s had been supplanted by the rise of quantification and formal, often statistical, models in the social sciences. Numbers, parameter estimates, and, especially, standard errors were precise. Pictures were- well, just pictures: pretty or evocative, perhaps, but incapable of stating a ``fact'' to three or more decimals. Or so it seemed to statisticians. But it is equally fair to view this as a time of necessary dormancy, application, and popularization, rather than one of innovation. In this period statistical graphics became ``main stream.'' It entered textbooks, the curriculum, and standard use in government, commerce and science. In this period graphical methods were used, perhaps for the first time, to provide new insights, discoveries, and theories in astronomy, physics, biology, and other sciences. As well, experimental comparisons of the efficacy of various graphics forms were begun, and a number of practical aids to graphing were developed. In the latter part of this period, new ideas and methods for multi-dimensional data in statistics and psychology would provide the impetus to look beyond the 2D plane.

74. Continuous Improvement
    W. Edwards Deming worked as walter shewhart's assistant and protégé andhelped further develop this radical approach to improving quality.  
    http://www.lmu.ac.uk/lis/imgtserv/tools/contimp.htm
    
    Extractions: Continuous Improvement Continuous improvement is not a tool or technique as such - more a way of life (or at least a cultural approach to quality improvement) - and the concept of continuous improvement has to be set in the context of 'the quality movement'. 'Quality' as a business issue - in the way we know it now - arose with labour specialisation, mass production and automation techniques - techniques which moved away from the traditonal expert craftsman approach to quality. In the new world of 'factories' and mass production, quality was obtained by inspecting each part and passing only those that met specifications. This was true until 1931 when Walter A. Shewhart, a statistician at the Hawthorne plant at Western Electric published his book Economic Control of Quality of Manufactured Product (Van Nostrand, 1931). This book is the foundation of modern statistical process control (SPC) and provides the basis for the philosophy of total quality management or continuous process improvement for improving processes. With statistical process control, quality inspection of each individual part produced is no longer used - the process is monitored through sampling. Dependent on the results from the sample, adjustments are made to the process to ensure 'quality' production.

    http://www.anu.edu.au/nceph/surfstat/surfstat-home/5-1-2.html
    
    Extractions: Surfstat. australia : an online text in introductory Statistics In the 1920's Walter Shewhart developed the idea of the control chart to help decide when the output of a process was part of " a stable system of chance causes", or whether there was an " assignable cause ". Shewhart viewed a stable system as one whose variation arose as the result of many small perturbations (which we call common cause variation ); for a stable process the observations could be described by a probability distribution - the system is said to be "in a state of statistical control", or simply, in control . An unusually large deviation suggested that the system had been disturbed and hence there was an assignable cause for the disturbance - the system is out of control , or unstable. Deming substituted the term special cause for assignable cause. Deming said that uncovering special causes was the responsibility of the local work force (those who had day-to-day contact with the process). Common causes were part of the system. The system is the responsibility of management. If the common cause variation is too large, it is the responsibility of management to change the system. Deming, stated that 85% of the problems with processes were system problems; later he increased this to over 94%, based on his own experience. Some authors regard this sharp delineation between special causes and common causes, workforce responsibility and management responsibility, as overly simplistic. For example, when a special cause is signalled, and its cause found (rarely an easy task), the local workforce may not have the authority to fix up the problem. Nevertheless, the distinction between special and common causes of variability is a useful one, and the recognition of responsibility assignments to the workforce for sporadic problems and to management for system problems is generally sound.

    Extractions: Introduction How did Statistical Quality Control Begin? Historical perspective Quality Control has been with us for a long time. How long? It is safe to say that when manufacturing began and competition accompanied manufacturing, consumers would compare and choose the most attractive product (barring a monopoly of course). If manufacturer A discovered that manufacturer B's profits soared, the former tried to improve his/her offerings, probably by improving the quality of the output, and/or lowering the price. Improvement of quality did not necessarily stop with the product - but also included the process used for making the product. The process was held in high esteem, as manifested by the medieval guilds of the Middle Ages. These guilds mandated long periods of training for apprentices, and those who were aiming to become master craftsmen had to demonstrate evidence of their ability. Such procedures were, in general, aimed at the maintenance and improvement of the quality of the process. In modern times we have professional societies, governmental regulatory bodies such as the Food and Drug Administration, factory inspection, etc., aimed at assuring the quality of products sold to consumers.
