Introduction Six sigma method is a project$-$driven management approach to improve the organization$$s products, services, and processes by continually reducing defects in the organization. It is a business strategy that focuses on improving customer requirement understanding, business systems, productivity, and financial performance. Dating back to the mid$-1980$s$,$ applications of the six sigma methods allowed many organizations to sustain their competitive advantage by integrating their knowledge of the process with statistics, engineering, and project management $($Anbari$,2002).$ Numerous books and articles provide the basic concepts and benefits of the six sigma method $($Harry and Schroeder, $2000)($Hoerl$,1998,2001).$ The challenges and realities in implementing the six sigma method successfully are immense. However, the benefits of applying the six sigma method to technology$-$driven, project$-$driven organisation are equally great. The objective of this paper is to review and examine the evolution, benefits, and challenges of six sigma practices and identify the key factors influencing successful six sigma project implementation. The paper also integrates the lessons learned from successful six sigma projects and their potential applications in managing traditional projects, and considers further improvements to the methodologies used for managing six sigma projects. Wider applications of six sigma principles to the organization will succeed through senior management involvement, organizational commitment, cultural change, and effective project management.
