Rectification of Defects Occurring in the Gate Valve Manufacturing Process by Implementing Six Sigma Methodology

Abstract

Six Sigma is a methodology containing various tools and techniques to make improvement in a process. The purpose of this research is to reduce the defects, maximize the profit, and make small scale industries more efficient. This Six Sigma Project was conducted at a valve manufacturing industry located in Maharashtra. The industry was performing at Sigma Level 3.0 and the newly achieved Sigma Level is 3.5. It is predicted that if the solutions are continuously applied for 6 months then the industry can achieve Sigma Level up to 4.0. A control plan was also provided to the industry which will help them to keep implementing the solutions for a longer period of time. A lot of energy and material wastage is prevented by reducing the defects which is a huge benefit for the environment in the long run.
