The Evolution of Human Sigma

Different quality management concepts, including Six Sigma, have been applied by many different types of organizations. Although much important work has been documented regarding Six Sigma, a number of questions remain concerning the applicability of these concepts in various organizations and contexts. Currently, limited research has been conducted on the Human Sigma approach. Therefore, the purpose of this article is to analyse the principles and philosophies of Human Sigma and its relationship to Six Sigma through a systematic review of the literature. It is suggested that this in turn will lead to a better understanding of the Human Sigma approach and ultimately bridge the gap in the literature. Therefore, the paper argues that much can be learned from the principles and practices of Six Sigma, however the discussion further provides an assessment of the Human Sigma principles and their potential suitability to tourism businesses. In particular, specific similarities and differences concerning areas such as methodologies, tools, and results are presented in this article.
