Total quality management (TQM) is a management philosophy focused on customer satisfaction through continuous improvement. The key elements of TQM include focusing on customers, employee involvement, and continuous improvement. TQM seeks to integrate all organizational functions to ensure quality is built into processes from the start. This approach aims to reduce costs from defects while increasing customer loyalty, market share, and productivity. Quality is defined in various ways including being product-based, user-based, manufacturing-based, and value-based. Quality gurus like Deming, Juran, and Crosby emphasized prevention over inspection and leadership commitment to long-term quality programs.
