Quality control circles (QCCs) are a proven method for fostering continuous improvement through employee involvement. However, the implementation process and organizational impact of QCCs in the food industry remain underexplored. This case study evaluates the implementation of QCCs by examining the benefits and challenges perceived by employees and managers, assessing QCC alignment with ISO standards, and providing actionable recommendations to optimize QCC implementation. Using a mixed-methods approach, the employee findings indicate that QCCs promote continuous improvement, enhance productivity, foster a positive culture of quality, and strengthen engagement and responsibility for product and process quality. Employees felt that their ideas were valued and that they received constructive feedback from leadership. However, they also identified challenges related to training and resource availability. From a managerial perspective, the ISO diagnostic tool revealed a 78.28% compliance rate with the QCC program planning, quality procedures, action plans, quality management system alignment, and documentation. Non-conformities included insufficient monitoring solutions, absence of effectiveness indicators, lack of risk assessments, and insufficient resources. Although managers acknowledged benefits such as improved engagement and communication, challenges such as limited human resources, high demand, and resistance to change were also noted. This paper concludes with recommendations for enhancing future QCC cycles and for creating a structured implementation process.
