During the past two decades, there have been growing interests on reducing different activities using outsourcing activities. Outsourcing allows us to focus only on value added activities, which helps reduce the size of organizations. In this paper, we present a new framework based on PMBOK, which determines and ranks important activities for outsourcing. The proposed model of this paper is implemented for a real-world case study in educational system. We have distributed a questionnaire among some decision makers and asked them about their opinions on outsourcing activities on Likert scale. We have compared the relative importance of four major activities including educational activities, research and development, administration and services. The results indicate that general services are the most important activities, which are suitable for partnership followed by administration activities. Educational and research activities and development are in lower important activities.
