In last few days i learned about how different authors made different combinations of lean and six sigma and how they implemented the combined methodology in real businesses. The compatibility of two approaches will depend upon the type of combination made by different tools. some combinations of lean and six sigma as first implement lean to reduce waste and then implement and increase efficiency then implement six sigma to reduce variation and improve quality. the other type of combination is implement six sigma first and follow DMAIC methodology as a framework to implement lean tools. Another type of combination is implementing lean and six sigma simultaneously as a holistic way. so every combination has its own thinking, but ultimately needs some practical experiments to see compatibility of each type of combination.
Also wants to share some good experience while doing PMA, I got lot of help form mindmap as this tool helps to diversify over thinking and keeps us motivating to think out of box.. i found this tool very important for planning PMA and then for executing the plan. We can start with mindmap then gradually we can edit it according to our need as we progress on our work.

Their are some tools of lean, which can be integrated, with six sigma tools. The combination will defiantly give more valuable results but it is not clear that will it work in every type of industries and at every time?
As my research is moving forward I am getting more and more knowledge about both methodologies. There are lots of similarities between this approaches and that’s why earlier they were competitors of each other. But on the other hand there are some basic fundamental differences as well, which can become substitutes for each other and they can be combined. The combination of this will provide a new approach, which deals with all variety of problems. But the compatibility is major issue. It is basically depends upon how you combine this two approaches.
This two approaches individually shown great results and lots of literatures says that the integration has lot more capability to improve process, but at the same time the exact combination is not has been came out and which tools has to combine with witch part of other process will determine their compatibility.

As we all know six sigma and lean are both different approaches of excellence and continuous improvement. Six sigma mainly recognised for defect reduction and quality improvement. Six sigma basically concentrates on variation of process and uses analytical methods to solve problem. Six sigma was introduced in 1980’s by Motorola then developed by General electronics in 1990’s, this development was mainly included cultural change associated with the process. As six sigma concentrates on quality is same as lean management. Lean is mainly focuses on west reduction, cycle time improvement and cost saving. Earlier lean and six sigma was known as competitors of each other as both process works on quality improvement and continuous improvement. Both approaches have concentration on customer satisfaction and process improvement. But basically both theories works on different way and their methods of workings are also different.
But now it is seen that both methods are combined with each other and it is seen that the most of them are working well. The new process called as lean six sigma(LSS) or lean sigma. They are combining to get more satisfied results. Both approaches have different tools and different way of working. So the compatibility is mainly depends upon how individual combines them. Both process shown their individual performance well so it is expected that combination will give excellent performance. As both approaches have same ultimate aim of excellence, but both need different resources to work on so it is mainly biased on how company combines resources for both of them and produces results. Compatibility may vary as per combination of resources and tools while implementing LSS.
