Quality circle

Quality circle is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Quality circle rather than just read about it. In short: A quality circle or quality control circle is a group of workers who do the same or similar work, who meet regularly to identify, analyze and solve work-related problems. It consists of minimum three and maximum twelve members in number.

Key takeaways

  • Quality circle belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Quality circle to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Quality circle from memory before moving on to harder problems.

Reference excerpt

A quality circle or quality control circle is a group of workers who do the same or similar work, who meet regularly to identify, analyze and solve work-related problems. It consists of minimum three and maximum twelve members in number. Normally small in size, the group is usually led by a supervisor or manager and presents its solutions to management; where possible, workers implement the solutions themselves in order to improve the performance of the organization and motivate employees. Quality circles were at their most popular during the 1980s, but continue to exist in the form of Kaizen groups and similar worker participation schemes. Typical topics for the attention of quality circles are improving occupational safety and health, improving product design, and improvement in the workplace and manufacturing processes. The term quality circles was most accessibly defined by Professor Kaoru Ishikawa in his 1985 handbook, "What is Total Quality Control? The Japanese Way" and circulated throughout Japanese industry by the Union of Japanese Scientists and Engineers in 1960. The first company in Japan to introduce Quality Circles was the Nippon Wireless and Telegraph Company in 1962. By the end of that year there were 36 companies registered with JUSE by 1978 the movement had grown to an estimated 1 million Circles involving some 10 million Japanese workers. The movement built on work by Dr. W. Edwards Deming during the Allied Occupation of Japan, for which the Deming Prize was established in 1950, as well as work by Joseph M. Juran in 1954. Quality circles are typically more formal groups. They meet regularly on company time and are trained by competent persons (usually designated as facilitators) who may be personnel and industrial relations specialists trained in human factors and the basic skills of problem identification, information gathering and analysis, basic statistics, and solution generation. Quality circles are generally free to select any topic they wish (other than those related to salary and terms and conditions of work, as there are other channels through which these issues are usually considered). Quality circles have the advantage of continuity; the circle remains intact from project to project. (For a comparison to Quality Improvement Teams, see Juran's Quality by Design.). Handbook of Quality Circle: Quality circle is a people-development concept based on the premise that an employee doing a certain task is the most informed person in that topic and, as a result, is in a better position to identify, analyse, and handle work-related challenges through their innovative and unique ideas. It is, in fact, a practical application of McGregor's Theory Y, which argues that if employees are given the right atmosphere and decision-making authority, they will enjoy and take pride in their work, resulting in a more fulfilling work life. A quality circle is a small group of workers that work in the same area or do similar sorts of work and meet once a week for an hour to identify, analyse, and resolve work-related issues. The objective is to improve the quality, productivity, and overall performance of the company, as well as the workers' quality of life at work. TQM World Institution of Quality Excellence publication division published a book, "Handbook of Quality Circle" by Prasanta Kumar Barik which tried to bring all the theoretical concepts with detailed implementation steps for Quality Circle. This will be useful in Quality Circle implementation in all types of organizations.

History Quality circles were originally described by W. Edwards Deming in the 1950s, Deming praised Toyota as an example of the practice. The idea was later formalized across Japan in 1962 and expanded by others such as Kaoru Ishikawa. The Japanese Union of Scientists and Engineers (JUSE) coordinated the movement in Japan. The first circles started at the Nippon Wireless and Telegraph Company; the idea then spread to more than 35 other companies in the first year. By 1978 it was claimed by JUSE in their publication Gemba to QC Circles, that there were more than one million quality circles involving some 10 million Japanese workers. As of 2015 they operate in most East Asian countries; it was recently claimed by the President of the Chinese Quality Circles Society at the ICSQCC Conference in Beijing 30 August 1997 that there were more than 20 million quality circles in China. Quality circles have been implemented even in educational sectors in India, and QCFI (Quality Circle Forum of India) is promoting such activities. However this was not successful in the United States, as the idea was not properly understood and implementation turned into a fault-finding exercise – although some circles do still exist. Don Dewar, founder of Quality Digest together with Wayne Ryker and Jeff Beardsley established quality circles in 1972 at the Lockheed Space Missile factory in California. TQM World Institution of Quality Excellence (TQM-WIQE) through its E-learning division Quality Excellence Forum (QEF) is providing training on Quality Circle with three different levels of certification for better implementation of Quality Circle worldwide. The certifications level are Quality Circle Fundamentals (QCF), Quality Circle Professional (QCP) and Quality Circle Master (QCM).

Worked examples

Example 1 — a first encounter with Quality circle

Start with the simplest possible case. Write down what Quality circle claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Quality circle before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Quality circle ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Quality circle

In research
Quality circle appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Quality circle in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Quality circle is common in secondary-school and first-year university syllabi. It links to neighbouring topics Quality management, so understanding it makes those chapters shorter.
In everyday life
Look for Quality circle outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

What is Quality circle in simple terms?

A quality circle or quality control circle is a group of workers who do the same or similar work, who meet regularly to identify, analyze and solve work-related problems. It consists of minimum three and maximum twelve members in number.

Why does Quality circle matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Quality circle?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
