The Problem solving methods and expertise teams strives to make complexity more manageable and bring the chronic problem into solution.

Such complex defect has consisted of so many sub-problems which must be solved and different parameters which must be brought under control. Using a very simple six sigma tools such complicated problem of this case study shows more than 60% DPU (Defect per Unit) improvement. The intent of writing this article is to present the reader with an actual case study for structuring and improvement of six sigma projects which does not need necessarily complex six sigma tools.
