Six Sigma is an approach that improves quality by analyzing data with statistics. In recent years there has been a significant increase in the use and development of the Six Sigma methodology in manufacturing industry and others. The Six Sigma approach has been increasingly adopted worldwide in the manufacturing sector in order to enhance productivity and quality performance and to make the process robust to quality variations. Understanding Methodology, key features, obstacles of the six sigma method allows organizations to better support their strategic directions, and increasing needs for coaching, mentoring, and training. It also provides opportunities to better implement six sigma projects.
This paper reviews Methodology, obstacles and Benefits of six sigma practices and identifies the key factors influencing successful six sigma project implementations. Also this paper is an attempt to review and present how the DMAIC methodology has been studied and researched by various researchers.

Six Sigma, DMAIC, Quality.


After comprehensive study of DMAIC approach it has been concluded that a number of industries adapting this approach to solve any quality or production related problems. This approach has been utilized by industrial engineers in library, manufacturing industries and service industries effectively to eliminate any customer related problem. DMAIC approach can be applied in any small or medium scale industry to remove problems associated with the products. The objective of review was to understand the status of Six Sigma as on yesterday, today and tomorrow. From the study done on the manufacturing industries in 21st century we conclude that Six Sigma is indeed a business strategy that can provide a breakthrough improvement in the competitive era. The key strategy for successful implementation of Six Sigma is that the industry applying it should follow a correct methodology and use of tools and techniques is done in such a manner that it gives effective solution to respective problem. Thus a use of proper combination of tools and techniques can lead to great benefits. This study will help manufacturing units to motivate and apply Six Sigma at their organization and reap high benefits. The current status suggests there is future scope of getting better and become a world-class level organization by reaching Sigma level above 5
