Total Quality Management (TQM)

Definition of quality: the ability (degree of accomplishments/excellence) of a product or service to satisfy the requirements of clients/customers

Total Quality Management (TQM) is a comprehensive and structured strategy to manage the quality of products and services by making improvements through continuous feedback and assessment.

In recent years, TQM requirements have been defined by organization to adherent to established standards, such as the International Organization for Standardization's (ISO, 1946) standards series. ISO 9000 (1987, 2000) family addresses "quality

management". ISO 14000 (1996, 2004) family addresses "environmental

management”
