The 5 whys is a robust tool for analyzing the root cause of problems in 6-sigma. 6-sigma is a management concept used to spot and remove wasteful practices which enables an organization to use minimal resources to actualize maximum yield. This implies that in 6-sigma, activities that do not add value to the entire process are removed, while the value-adding activities are enhanced to ensure good quality and customers are satisfied. 6-sigma has a well-defined quality improvement methodology known as DMAIC which is an acronym that stands for the processes involved in this methodology. DMAIC stands for define, measure, analyze, improve and control. The 5 whys belong to the “Analyze” phase of DMAIC. | |||

Problems occur at various points in our day to day running of businesses, but it is known that problems are only symptoms of underlying causes.
