After analysing a sample of 442 of the Spanish biggest manufacturing companies, some evidence about the influence of total quality management (TQM) on the companies’ operating performance has been obtained. However, companies applying TQM together with the ISO 9000 standards did not show positive results. This fact leads to the consideration that, despite the beliefs about ISO 9000 as a good first step in the way of implementing TQM, once implemented, some of the ISO 9000 principles are contradictory with TQM philosophy. These not congruent systems applied together would drive the company to obtain less benefits than the use of only one of them. The study concludes that when ISO 9000 and TQM are applied simultaneously, the resultant benefits to the company are not better than those experienced if either system were applied in isolation.
