Total Quality Management (TQM) has evolved over time from a focus on inspection to ensure quality to a holistic approach aimed at achieving excellent performance and customer satisfaction. Key developments included the introduction of statistical process control in the 1920s and quality practices spreading from Japan to the West in the postwar period. TQM involves all employees and aims to meet customer needs through a process-based approach, leadership commitment, and a focus on continual improvement. The core goals are delighting customers and building competitiveness through quality.
