Quality circles are voluntary groups of employees led by a supervisor that are trained to identify, analyze, and solve work-related problems to improve organizational performance. They meet regularly to select problems, analyze causes, generate solutions, and present recommendations to management. Quality circles aim to improve product quality, productivity, occupational safety and health, and enrich employees' work by treating workers as valuable human resources and fostering participation and problem-solving. When successfully implemented with management support, quality circles can develop leadership and teamwork while increasing motivation, morale, and upward information flow in an organization.
