The Shainin Medal

In 2003, ASQ established an award to recognize the development of statistical methods for solving quality problems in products or services. The award was named for Dorian Shainin, a leading authority on product quality and reliability. During a professional career that spanned nearly six decades, Shainin developed more than 20 statistical techniques for solving problems, controlling processes, and developing highly reliable products.

In 2003, ASQ established an award to recognize the development of statistical methods for solving quality problems in products or services. The award was named for Dorian Shainin, a leading authority on product quality and reliability. During a professional career that spanned nearly six decades, Shainin developed more than 20 statistical techniques for solving problems, controlling processes, and developing highly reliable products.

After earning a degree in aeronautical engineering at MIT, Shainin began his career as a design engineer for the Hamilton Standard division of United Aircraft. In 1939, he was assigned to work with suppliers to help solve technical problems. These problems were limiting Hamilton Standard’s ability to provide critical propeller systems for the war effort. Shainin quickly discovered that he could solve problems faster and more effectively by “talking to the parts” rather than talking to the engineers. While the engineers would speculate and develop lists of potential causes, the parts always revealed the real root cause, if you knew how to speak their language. This insight drove Shainin’s approach to problem solving for the remainder of his career.

In 1946, he developed his first statistical technique, the Hamilton Standard Lot Plot. This was a graphical method for evaluating the quality of an incoming lot based on measuring a random sample of 50 units. Developing new techniques requires perseverance and Lot Plot was no exception. Shainin had to demonstrate to the Navy Bureau of Aeronautics that Lot Plot was more effective than 100 percent inspection—a conclusion that was counter-intuitive. In 1951, Shainin’s article on Lot Plot was recognized with the Brumbaugh Award for the most influential article of the year.

Shainin’s most significant contribution was his discovery of the Red X®1 model of systems variation. The prevailing wisdom held that variation causes could be discovered and controlled until the system reached a state of statistical equilibrium. At that point, the remaining causes were believed to be random and undiscoverable. Any further improvement would require a redesign of the system. However, Shainin found that by talking to the parts, he could find variation causes within stable systems. He concluded that Juran’s Pareto principle must apply to the causes of system variation. No matter how many causes had already been identified and controlled, among the remaining causes there must be one that contributed more to the overall variation than any other. He called this cause-effect relationship the Big Red X.
Because of the way sources of variation combine to create overall system variation, it is not possible to make a significant improvement unless you find and control the Red X. For the rest of his professional career, Shainin focused on promoting and developing statistical tools that aided in the search for the Red X. Shainin followed three principles for solving variation problems:

1. There is always a Red X.

2. The fastest route to identifying the Red X is a progressive search using a process of elimination.

3. Talk to the parts with tools that are both statistically simple and rigorous.

In the early 1960s, Shainin served Grumman Aerospace as a reliability consultant for the lunar module of NASA's Apollo project. The lunar module prototype components and systems had been empirically tested using the Shainin multiple environment overstress probe testing system to be statistically sure that even the weakest failure mode had a statistical margin of safety. NASA initially awarded that contract to Grumman because no other aerospace competitive proposal demonstrated that safety ability.From 1950 through 1983, Shainin was on the faculty of the University of Connecticut, where he originated and conducted the continuing education program for people in industry. At one of his seminars, the medical directors of two Connecticut hospitals convinced him to work on some of their critical management problems. As a result, The Newington Children's Hospital (now part of the Connecticut Children's Medical Center) appointed him statistical consultant to the medical staff from 1957 to 1994. Thus, he had the opportunity to adapt several of his techniques to the problems of the etiology of infirmities, particularly disabled children.

The Shainin Medal is awarded for the development and application of creative or unique statistical approaches in solving problems relative to the quality of product or service. The recipients of the Shainin Medal have been recognized for the development of a specific technique. The committee evaluates nominations with an emphasis on creativity, uniqueness, and usefulness.

To date, the medal has been awarded seven times. The medalists are:

Carl Bennett (2004), for the development of a new method for analyzing the results of designed experiments that more accurately represents the effects of interactions.

Nicholas Squeglia (2005), for the development and promotion of attribute sampling plans based on a c=0 standard.

Yoji Akao (2006), for the development of quality function deployment (QFD): a process to ensure that the voice of the customer is heard throughout the product development process.

Jane Hoying (2008), for the development of a new system for optimizing business systems and solving business process problems based on a functional analysis of the system.

Stephen Luko (2009), for the development of a sampling system for multi-station manufacturing processes to ensure that each stream is represented.

Wayne Nelson (2010), for developments in data analyses for product reliability, accelerated testing, and repair data.

Jack ReVelle (2012), for the development of a new system for applying statistical methods to construction processes.

Each of these developments was practical and useful. Each was a unique development, often improving on existing technology. Each required creativity and some form of promotion to encourage its use.
