The Implementation of Six Sigma and DMAIC Methodology To Increase Productivity and Meet Customer Requirements

Abstract

The Lean Six Sigma approach has become a popular initiative which companies have embarked on to remain competitive, ensure growth within the global market and to establish customer satisfaction and loyalty. Six Sigma is at the top of the agenda for many companies that aim to reduce cost and improve a firm's productivity. This paper focuses on a production that was unable to meet the hourly target. Using the six-sigma approach and DMAIC methodology, the current problems on the line were studied and the root cause was established by using a fish bone diagram. Process improvement initiatives were characterised by the installation of a conveyor, synchronised with the takt time, and the production line was able to meet the daily output a. An Andon system was also installed to keep track of scoring, to ensure each process meets their required cycle time and process operation as well as to indicate to line management if there is an abnormality at any process or holistically.
