Decision makers working on effectiveness want to know all the scenarios on how to make ineffective decision making units to be effective. Data Envelopment Analysis, which takes into account multiple inputs and outputs, provides guidance on both the calculation of the effectiveness of the decision-making units and how the ineffective units should behave in order to be effective depending on the reference sets formed as a result of the analyzes. Determining the effectiveness of universities is very important for both the management and the students who will choose the universities. The performance of faculty members plays an important role in determining the prestige of departments and the university in general among other universities.
