The roots of Total Quality Management (TQM) can be traced back to early 1920s when statistical theory was first applied to product quality control. This concept was further developed in Japan in the 40s led by Americans, such as Deming, Juran and Feigenbaum. The focus widened from quality of products to quality of all issues within an organisation the start of TQM.
The following shows the history of Total Quality Management, from inspection to business excellence.
Inspection involves measuring, examining, and testing products, process and services against specified requirements to determine conformity.
The use of inspection has been evident throughout the history of organised production. In the late Middle Ages, special measures were taken to inspect the work of apprentices and journeymen in order to guard the Guild against claims of makeshift or shoddy work.
During the early years of manufacturing, inspection was used to decide whether a worker s job or a product met the requirements; therefore, acceptable. It was not done in a systematic way, but worked well when the volume of production was reasonably low. However, as organisations became larger, the need for more effective operations became apparent.
In 1911, Frederick W. Taylor helped to satisfy this need. He published The Principles of Scientific Management which provided a framework for the effective use of people in industrial organisations. One of Taylor s concepts was clearly defined tasks performed under standard conditions. Inspection was one of these tasks and
- was intended to ensure that no faulty product left the factory or workshop;
- focuses on the product and the detection of problems in the product;
- involves testing every item to ensure that it complies with product specifications;
- is carried out at the end of the production process; and relies on specially trained inspectors.
This movement led to the emergence of a separate inspection department. An important new idea that emerged from this new department was defect prevention, which led to quality control.
Inspection still has an important role in modern quality practices. However, it is no longer seen as the answer to all quality problems. Rather, it is one tool within a wider array.
Quality Control and Statistical Theory
Quality Control was introduced to detect and fix problems along the production line to prevent the production of faulty products. Statistical theory played an important role in this area. In the 1920s, Dr W. Shewhart developed the application of statistical methods to the management of quality. He made the first modern control chart and demonstrated that variation in the production process leads to variation in product. Therefore, eliminating variation in the process leads to a good standard of end products.
Statistical Quality Control:
- focuses on product and the detection and control of quality problems;
- involves testing samples and statistically infers compliance of all products;
- is carried out at stages through the production process; and
- relies on trained production personnel and quality control professionals.
Shewart s work was later developed by Deming, Dodge and Roming. However, manufacturing companies did not fully utilise these techniques until the late 1940s.
Quality in Japan
In the 1940s, Japanese products were perceived as cheep, shoddy imitations. Japanese industrial leaders recognised this problem and aimed to produce innovative high quality products. They invited a few quality gurus, such as Deming, Juran, and Feigenbaum to learn how to achieve this aim.
Deming suggested that they can achieve their goal in five years; not many Japanese believed him. However, they followed his suggestions. Maybe the Japanese thought it was rude to say that they did not believe Deming. Or maybe they thought it would be embarrassing if they could not follow his suggestions. Whatever reason it was, they took Deming s and other gurus advice and never looked back.
In the 1950s, quality control and management developed quickly and became a main theme of Japanese management. The idea of quality did not stop at the management level. Quality circles started in the early 60s. A quality circle is a volunteer group of workers who meet and discuss issues to improve any aspects of workplace, and make presentations to management with their ideas.
A by-product of quality circles was employee motivation. Workers felt that they were involved and heard. Another by-product was the idea of improving not only quality of the products, but also every aspect of organisational issues. This probably was the start of the idea, total quality.
The term total quality was used for the first time in a paper by Feigenbaum at the first international conference on quality control in Tokyo in 1969. The term referred to wider issues within an organisation.
Ishikawa also discussed total quality control in Japan, which is different from the western idea of total quality. According to his explanation, it means company-wide quality control that involves all employees, from top management to the workers, in quality control.
Total Quality Management
In the 1980s to the 1990s, a new phase of quality control and management began. This became known as Total Quality Management (TQM). Having observed Japan s success of employing quality issues, western companies started to introduce their own quality initiatives. TQM, developed as a catchall phrase for the broad spectrum of quality-focused strategies, programmes and techniques during this period, became the centre of focus for the western quality movement.
A typical definition of TQM includes phrases such as: customer focus, the involvement of all employees, continuous improvement and the integration of quality management into the total organisation. Although the definitions were all similar, there was confusion. It was not clear what sort of practices, policies, and activities needed to be implemented to fit the TQM definition.
Quality Awards and Excellence Models
In 1988 a major step forward in quality management was made with the development of the Malcolm Baldrige Award in the United States. The model, on which the award was based, represented the first clearly defined and internationally recognised TQM model. It was developed by the United States government to encourage companies to adopt the model and improve their competitiveness.
In response to this, a similar model was developed by the European Foundation of Quality Management in 1992. This EFQM Excellence Model is the framework for the European Quality Award.
While leading organisations compete to win awards, the main purpose of these awards is to encourage more companies to adopt quality management principles. The models are practical tools; they help organisations to measure where they are now and where they want to be in the future. The models also help organisations to create a plan to reduce the gap between these positions.
Today, hundreds of quality awards and several models exist all over the world. For more information on some of these models, visit Excellence Models .
TQM models are often called Business Excellence Models. Also, TQM itself is now often called Business Excellence. This is to distinguish the new TQM from the past work on TQM.
As mentioned earlier, there was confusion as to what TQM was in the 80s and early 90s. This was because any business improvement programme was becoming called TQM. Therefore, the name TQM became tarnished.
Business Excellence is really the same as TQM, but with a more clearly defined approach.
How the BPIR can help Quality Practioners and Managers
Increasing number of organisations, large or small, have become involved in TQM/Business Excellence in the new millennium. The Centre for Organisational Excellence Research (COER ), recognised the need for resources devoted to this area and launched the BPIR.com in April 2002.
Today, the BPIR.com members area provides the most comprehensive information and services related to quality, quality management, TQM and Business Excellence. Whether you are quality practitioner or a manager focussed on business improvement, the resources within the members area will help you to have a greater impact within your workplace.
