Based on the comparative analysis conducted, two similar instruments in questionnaire with alike content were developed to measure the level of implemention of TQM in the organizations implementing TQM and to collect the views of quality experts respectively. Through statistical tests, reliability and validity including construct validity of the mentioned above instruments were approved by factor analysis. Finally by analyzing the data collected from the two instruments a gap analysis aimed at identifying the differences between what is really done in the organizations and what quality experts believe that should be done was performed.
