Industrialization at the end of the 19th century and the start of mass production at the beginning of the 20th century created a need to control and to produce quality.
Both Walter A. Shewhart (inventor of PDCA and statistical control) and later his disciple Edward Deming (Deming wheel = PDCA) used the scientific approach (both were trained physicists) to solve problems and to control quality: - define the system that you want to observe - observe this system - pick up information and take measurements - cluster/categorize this information/measurement and based on these facts ... - ... hypothesize about possible effect-cause-effect relationships in this system - experiment to falsify or verify your hypothesis and then ... - ... update your standards (drawings, processes, specifications). Today this approach is embedded in the well-known problem solving methodologies of 8D, A3, QRQC, 6sigma ...
