Six sigma is a popular approach to drive out variability from processes using powerful statistical tools and techniques. Although originally introduced by Motorola in 1986 as a quality performance measurement, six sigma has evolved into a statistically oriented approach to process and product quality improvement. Many organisations have reported significant benefits as a result of six sigma project implementation, though not all are yet success stories. This paper reviews the literature related to the critical success factors for the effective implementation of six sigma projects in organisations.
