Аннотация:Abstract Lean Six-Sigma technology is considered as a powerful business strategy for employing a well-structured continuous improvement methodology to effectively reduce process variability and increase quality in business processes using statistical tools. However, the academic literature still contains few empirical studies of Six-Sigma approach. This investigation describes a procedure that applies Six-Sigma approach to enhance quality in touch panel manufacturing. The empirical study illustrates methods used to Define, Measure, Analyse, Improve and Control (DMAIC) approach of Six-Sigma. The Six-Sigma empirical study mentions the functions and efficiency of the touch panel industry and the same process can be extended to numerous other examples in the industry.
