Success Factors and Benefits of Six Sigma Implementation in Hospitals: A Systematic Review

Rashid M. Alhamali


This review explores critical success factors of Six Sigma implementation in hospitals and identifies the benefits. Data sources and Methodology: Prior studies on Six Sigma (SS) totaling 100 were selected from more than 100 journals. These studies came from numerous databases and are classified based on the year of publication. Journal names with corresponding number of papers selected are reported. The review reveals 25 critical success factors (CSF) necessary in the implementation of Six Sigma, encompassing numerous aspects of an organization such as managerial, statistical, and technical aspects. Twenty benefits derived from SS’s implementation are identified, including various improvements in terms of the organizations’ processes, financial performance, and quality of service. The success of Six Sigma implementation depends on several critical factors, some of which are best considered before its introduction, while others must be addressed during the process itself. Other factors are external and should be considered during and after its implementation. Not all Six Sigma initiatives are successful nor result in great benefits. Therefore, organizations must analyze their need for Six Sigma projects and base their decisions on the availability/presence of the CSF. Organizations, including hospitals, can gain numerous benefits from Six Sigma implementation but must first evaluate Six Sigma’s introduction and implementation against their abilities to achieve desired outcomes.
