Improving the same process from different angles
Six sigma and lean today could be seen as most popular improvement methodologies with many followers across different industries. Both methodologies proved their effectiveness and ability to work and be successful on their own. As they develop scholars and companies realize their strengths and limitations and try to combine them with other quality initiatives, which could eliminate those benefits and support strengths. However sometimes attempts fail because of contradictory or conflict nature of combined approaches. As far as six sigma and lean are concerned combination of both is seen as successful in both literature and practice. Their combination, in general, is easy to implement. There is no rigid structure both in lean and six sigma and there is no barriers for their combination as they just themselves a combination of different tools and techniques. Both lean and six sigma are organization of different tools to solve particular and different from each other problems, but the problems, which could occur in the same process, therefore six sigma and lean do not contradict each other as they see and cure the same process from different, non-conflict angles and aspects.
