Historical Review of TQM:

Industrialization led to mass production in which it led to the concept of one product at a time to the assembly line of production. Though workmanship was affected but mass production led to more job and reduction in cost of the product and increase in quality, reduction of defects etc.

1924 - After WWI, W.A. Sherwat of Bell Telephone statistical chart for the control of various. Concepts of sample tests were followed. It was a failure in the initial stages.
1946 - ASQC American Society for Quality Control, now ASQ. Frequent meetings, conferences and publications were made to public.
1950 - W.Edwards Demings his guidance and lecture to Japan engineers transformed quality concepts in the organization. His cycle PLAN-DO-CHECK-ACT
1954 - Joseph M.Juran Concept of efficient and productive. Juran Trilogy Quality planning - Quality Control - Quality Improvement
1960 - Quality control circles were formed. Zero defects concepts
1970 - Reactive approach to proactive approach. Shift from Japan to USA
1980 - SPC - Statistical Process Control. Concepts of parameter and tolerance. Experiments 1990 - Concepts of certification of ISO, CMM etc
2000 - Six sigma concept - Six Sigma stands for Six Standard Deviations (Sigma is the Greek letter used to represent standard deviation in statistics) from mean. Six Sigma methodology provides the techniques and tools to improve the capability and reduce the defects in any process.



What is SPC?
Statistical process control (SPC) is a method of quality control which employs statistical methods to monitor and control a process. This helps to ensure that the process operates efficiently, producing more specification-conforming products with less waste (rework or scrap).
What is Six Sigma?
Six Sigma is a set of techniques and tools for process improvement. It was introduced by American engineer Bill Smith while working at Motorola in 1986. Jack Welch made it central to his business strategy at General Electric in 1995
