Quality circles are voluntary groups of workers that meet regularly to identify, analyze, and solve work-related problems in order to improve performance. They aim to develop workers' skills and a sense of teamwork while enriching jobs. Quality circles go through a process where they select problems, analyze causes, generate solutions, and present their recommended solution to management for potential implementation. They can benefit organizations by developing leadership, improving morale, boosting quality and productivity, and strengthening communication between workers and management. However, they require strong management support to avoid issues like unrealistic expectations, lack of training, and failure to implement solutions.
