A quality circle is a type of industrialised group production or work team, often found in manufacturing or service industries, where workers who are involved in a particular area of work come together regularly to use their collective expertise and knowledge to actively participate in problem-solving, decision-making, and continuous improvement processes related to the quality of products, services, or work processes. These circles typically involve a small group of employees who meet voluntarily and are trained in problem-solving techniques to identify, analyse, and propose solutions to work-related issues, aiming to enhance efficiency, productivity, and the quality of outcomes by leveraging the insights and experiences of those directly involved in the work.
