The development of positivity in organizational communication can lead to increased convergence among individuals and enhance the organization's status. Therefore, the research problem of the present study is how to use the capacity of the scientific foundations of positive organizational behavior to improve the quality of organizational communication. Accordingly, the aim of the present study is to design a model for enhancing organizational communication by utilizing the foundations of positive organizational behavior. This research is considered exploratory. In the qualitative phase, the thematic analysis method was used, and in the quantitative phase, the confirmatory factor analysis method and Smart PLS software were employed. In the qualitative phase, in order to design the research model, interviews were conducted with 24 academic and executive experts who were purposefully selected. Based on the findings, three categories of variables were identified, including communication drivers, communication networks, and communication actions. Additionally, five dimensions—ethical, human, functional, developmental, and emotional—were identified for social networks. Moreover, three categories of actions, including facilitating, moderating, and enabling actions, as well as three categories of drivers, including organizational, employee-related, and external drivers, were identified. In the quantitative phase, to validate the model, opinions were collected from 189 managers and experts in the Ministry of Communications and Information Technology. The sampling method was simple random sampling, and the data collection tool was a questionnaire. The findings showed that the identified variables were confirmed. The research results indicated that utilizing the foundations of positive organizational behavior in enhancing organizational communication is highly complex, and success in this area can yield valuable outcomes.
