Review of Six Sigma Methodology and Future Scope

Abstract

his article is an attempt to review and portrays how the six sigma methodology is studied by various
scholars and researchers.
Modernisation, Exalt Technology, and raised worldly customer demand change the way of managing trade. The
financial conditions and improvement towards better efficiency of a manufacturing sector totally depends upon
continuous improvement in achieving less variation, cost and high quality of end products. Six sigma method
become the best powerful strategy to sustain in a market for achieving manufacturing superiority. In
manufacturing sectors it is very difficult to control cost and to uphold high productivity and completing the
changing expectations of the customers. On implementing six sigma, manufacturing excellence and high level of
quality and productivity can be achieved. Six sigma is a smarter approach to manage a business/organisation. It
is a customer focused continuous improvement strategy and discipline that minimizes defects and variation
towards an achievement of 3.4 defects per million opportunities in product design, production, and
administrative processes. Six sigma is a technique to increase quality and profitability by eliminating and
removing causes of defects during manufacturing. Six sigma is a data driven fact based technique. The objective
of this article is to present an overview of six sigma DMAIC (Define, Measure, Analyse, Improve and
Control)methodology. The problem solving steps used for six sigma methodology are also studied in brief. As a
lone authoritative account of the DMAIC method does not exist, the article uses a large number of sources,
consisting of prescriptive accounts of the method in the practitioner literature.
