Six Sigma vs TQM: some perspectives from leading practitioners and academics

Abstract

PurposeThis paper aims to present the fundamental and critical differences between two of the most powerful philosophies of modern quality management.Design/methodology/approachThe approach taken was to form a panel of leading academics and practitioners who are familiar with both the Six Sigma and Total Quality Management (TQM) topics.FindingsThe findings of the panel discussion were quite stimulating in the sense that the paper demystifies the myth that Six Sigma is an old wine in a new bottle or that it is another hot topic or flavour of the month. The author believes that this will be extremely useful to many practitioners and researchers in these fields.Research limitations/implicationsThe viewpoints expressed here are based on many practitioners and academics in a few countries such as the USA, Singapore, India, the UK and Korea. It is essential to collect data on this topic from a number of leading researchers and practitioners in the field from other countries and to set out a research agenda in the future.Originality/valueThe paper provides an excellent resource for those people who are currently carrying out research in Six Sigma. Moreover, it is equally useful to practitioners and academics to understand the critical differences between these two powerful approaches to quality management.
