The manufacturing process of electronic switches involves a complex set of operations that can give rise to various quality issues. In this paper, we present a case study in which a small advisory & consulting company applies the seven basic quality tools to solve a quality issue in the manufacturing of electronic switches. The case study demonstrates how the cause-andeffect diagram, check sheet, control chart, histogram, Pareto chart, scatter diagram, and stratification can be used to identify, analyze, and solve quality issues. The paper provides a detailed description of the materials and methods used in the case study, as well as the results and discussions of the application of the seven basic quality tools. The case study shows that the tools were effective in identifying the root cause of the quality issue, analyzing the data, and suggesting solutions to improve the manufacturing process of electronic switches. The paper concludes that the seven basic quality tools are essential for any organization that seeks to improve its quality management processes and maintain a competitive edge in the market.
