No Quality Improvement Without Measurements
Elimination of measuring the quality, productivity & performance (system + individual) at each and every stage of production or development do not help any business survive long in the market, for sure. Deming's principles are overly people dependent
and blame the system when something goes wrong, which might not be true most of the time. This would have probably increased waste, inventory, production/labour costs while significantly lowering the productivity. It probably worked in the 40's and 70's just because nothing else existed.
In modern business environments, TQM/TPS principles might be used as a mere reference while embracing the concepts of Six Sigma and LEAN which are more process/data oriented and proven beyond doubt.
