Purpose – In this study, the effects of the different models and tools of quality management are examined. The purpose is to identify differences in the effects generated by different qualitymanagement models and tools.

Design/methodology/approach – A questionnaire was mailed to 500 Swedish quality professionals. The questions concerned their companies’ adoption of the values of TQM, the use of the models and tools of TQM and the effects they notice. Correlation analysis and multiple regression analysis were carried out.

Findings – The findings show that there is statistical correlation between the adoption of the values of TQM and successful quality management. The usefulness of the Swedish Quality Award, the European Quality Award and ISO 9000 as well as several of the quality management tools is also indicated. Regarding ISO 9000 specific effects have been found.

Research limitations/implications – A limitation of the study is that the financial outcomes of the quality management practices are not measured but only the managers’ perceptions of effects produced. The implication for further research is an increased knowledge of the different effects of the quality management practices and the significance of the values, particularly three values that were included in the multiple regression models.

Practical implications – The specific findings on the effects of ISO 9000 are useful for managers when implementing the standard. The results of the study also indicate the importance of emphasising the values for successful quality management.

Originality/value – This study has provided more detailed knowledge of the effects of the differentquality management practices, particularly of ISO 9000.
