The document summarizes Joseph M. Juran's quality management trilogy. The trilogy involves three processes: quality planning, quality control, and quality improvement. Quality planning establishes goals and processes to meet customer needs. Quality control evaluates performance against goals and acts on differences. Quality improvement identifies and implements projects to diagnose and remedy issues and sustain gains. The trilogy provides a framework for organizations to continuously improve quality and business results through better understanding the relationships between planning, controlling, and improving processes.
