In this article we propose the use of models of item response theory (IRT) in the constructs analysis of the total quality management (TQM) as an alternative to the classical measure theory (CMT). Interpretations of the model parameters are done. The results show that the IRT can be a powerfull tool in the analysis of TQM implementations as also in the study of organizational maturity in quality philosophy.
