The main purpose of this paper is to compare and discuss the evolution
of six important management systems: Japanese Total Quality Control
(JTQC), Total Quality Management (TQM), Deming's System of Profound
Knowledge, Business Process Reengineering (BPR), Lean Thinking and Six
Sigma. Indeed the contribution of this work lies in the concurrent
analysis and classification, by the means of a literature review, of the
results and critical implementation factors of the six systems. Deming's
Plan-Do-Check-Act (PDCA) has been used to classify the findings from the
literature review.
