Total Quality Management (TQM) is a quality management approach that seeks to provide long-term success by providing unparalleled customer satisfaction through the constant delivery of quality services. TQM requires all members of an organisation participate in improving processes, products, services, and the culture in business processes. TQM was developed by William Deming, a management consultant whose work had a great impact on Japanese manufacturing.

Reference Definition by Wikipedia: Total Quality Management (TQM) consists of organization-wide efforts to install and make permanent a climate in which an organization continuously improves its ability to deliver high-quality products and services to customers. While there is no widely agreed-upon approach, TQM efforts typically draw heavily on the previously developed tools and techniques of quality control. TQM enjoyed widespread attention during the late 1980s and early 1990s before being overshadowed by ISO 9000, Lean manufacturing, and Six Sigma.
