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.
