I did ask the difference year ago - TQM and Six Sigma, however it did not have any response.
In my opinion, Quality may mainly have two parts of measurment:
Qualitive will be feeling e.g. Thanks for my mother's Fire Rice.
Quantitve will be data e.g. Rejection rate is high in accordance with AQL table.
However, the Quality Mission/Objective will be the directive to the driver who lead the Quality with the fully support from top management in accordance with TQM concept.
