As part of the CQI’s centenary celebrations, Quality World focused on the past 100 years, looking at each decade, to provide readers with examples of major developments that influenced the quality profession.

Quality World created a timeline looking at the CQI's major milestones over the past 100 years.


The 1920s saw the birth of statistical process control. In the early 1920’s, Walter A Shewhart, a physicist, engineer and statistician from New Canton, Illinois, USA, prepared a notable memorandum which described the essential principles of statistical quality control (SQC) and which also contained a simple control chart, for Bell Labs, where he was working at the time.


The 1930s was a time of innovation and technological advancements. QW focused on Australian-born sociologist Elton Mayo and his experiments at Hawthorne Worls, a Western Electric factory in Chicago, US.
