In this research we have examined the relationship between organizational knowledge management and success of companies in food industry. The model of knowledge circular process (including creation, sharing, internalization, collecting and function of knowledge) is used to evaluate the knowledge management of organizations. Also the Rate of Return on Investment (ROI) was used to evaluate the success of companies. Admittedly our purpose was the evaluation of knowledge based competitive advantage theory and the relationship between knowledge management and attaining sustainable competitive advantage. The results of this research imply that creation and use of knowledge have the strongest relationship with acquisition and maintenance of competitive advantage.
