In the competitive world of today, the optimal use of environmental opportunities and generating sustainable competitive advantage are the main concerns of organizations. Competitive intelligence (CI) is one of the important techniques in creating competitive advantage. The aim of the present study was to specify the factors affecting CI in the organization. The conceptual model proposed examined the relationship between CI with the concepts of “entrepreneurial vigilance” and “market sense.” A questionnaire was used to collect data. The findings showed that three factors of entrepreneurial vigilance, market sense, and marketability of the organization are considered as factors affecting competitive competitiveness in organizations. Moreover, with a focus on market developments, the analysis of events and environmental changes and strengthening market sensitivity through strategic information exchange and strengthening the multidimensional perspective towards the market, a market-oriented organization treats its environment with a comprehensive approach and examines the environment and competitors with entrepreneurial vigilance. Therefore, by adopting strategic decisions, the organization enhances its CI and creates a sustainable competitive advantage. Ultimately, some suggestions were put forward to enhance CI of organizations.
