Application of Six Sigma to Reduce First Time Yield Loss of Power Contactor

Roshan K. Bhangale, Aadam I. Harnekar

Abstract: In Industry, there occurs a considerable amount of rejections of power contactors due to some manufacturing mistakes. This results in production of faulty contactors which are to be remanufactured and which takes a considerable amount of time and labor. In order to avoid this excess labor the First Time Yield (FTY) of the contactor is to be improved. To improve the First Time Yield (FTY) different quality improvement tools of Quality Improvement are deployed. Six Sigma is one of them which seek to improve the quality of the output of a process by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes. This paper discusses the quality and productivity improvement in a manufacturing enterprise. The paper deals with an application of Six Sigma DMAIC (DefineMeasure-Analyze-Improve-Control) methodology in an industry which provides a framework to identify, quantify and eliminate sources of variation in an operational process in question, to optimize the operation variables, improve and sustain performance. This paper presents and discusses the improvement in FTY after implementation of the Quality tools.
