A comparative analysis of lean manufacturing, Six Sigma and Lean Six Sigma for their application in manufacturing organisations

Manufacturing organisations are always on lookout for the best available way to keep control over the scraps and other industrial wastes in order to keep them competitive in the present scenario. Nowadays, there is a matter of discussion among various manufacturing organisations on which waste management technique is better among leading techniques such as lean manufacturing, Six Sigma and Lean Six Sigma. Various experts had recorded their viewpoints in this regard, but still there is confusion in the minds of the practitioners regarding the comparison of these leading techniques. Therefore, in the present study, a systematic comparative analysis of lean manufacturing, Six Sigma and Lean Six Sigma has been presented on various basis such as the history and growth of these techniques, important tools and techniques of these techniques, critical success factors, their areas of implementations, etc.; so that practitioners can identify the basic difference among these techniques and can choose the best available technique for implementation in their manufacturing organisations on the basis of the requirement of the situations.
