Quality Circles are voluntary groups of employees that meet regularly to discuss and solve work-related problems. They aim to improve quality, productivity, employee morale, and involve workers in decision-making. Quality Circles use organized problem-solving techniques like identifying issues, analyzing causes, generating solutions, and selecting the best approach. They were first developed in Japan in the 1960s and exported to the US, but saw reduced use later as Total Quality Management rose in the 1980s. Quality Circles can be effective if implemented properly with training, empowerment and management support.
