Total Quality Management (TQM) is a strategy for improving business performance through commitment and involvement of all employees to fully satisfy customer requirements. It focuses on continuous improvement of products, services, processes, and people. Six Sigma seeks to improve quality and minimize variability in processes. The principles of TQM include producing quality work the first time, focusing on customers, continuous improvement, teamwork, and adding value. Tools used include Pareto charts, histograms, fishbone diagrams, and flow charts. Key elements are leadership, employee involvement, and continuous improvement. Implementing TQM requires commitment, defining objectives, identifying resources, and ongoing review and improvement.
