The organizational project management maturity model (OPM3) aims to implement project management principles into project-based organizations. In fact, OPM3 by focusing on organizational level, can help construction companies to integrate their various activities and follow their goals strategically. However, this useful tool has not been recognized by most of the Iranian construction organizations. The purpose of this research is to introduce OPM3 to the experts and collect their views on how it can be implemented in their projects. First, the concept of OPM3 introduced to participants. To reach this aim, 52 questions were selected from PMI self-assessment questionnaire. These questions were categorized under four groups of planning, performance, procurement and prediction. Interviewees answered each question with Yes and No and then scores were added up in each group. At the next step, based on maximum and minimum score of groups a qualitative interview was carried out to understand reasons behind scores attained by interviewees. Identifying detailed elements can enhance the Iranian practitioners’ understanding about OPM3 and help them to apply it to their organizations in Iran’s working conditions.
