摘要：Performance measurement is important in the comparison among enterprises. These comparisons provide the opportunity to compare strong and weak aspects of enterprises with each other that have same work structure producing similar products. Through the comparisons, enterprise aims to make its performance better by taking the best, good or average performing enterprises operating in its field as references to itself. In this study, information technology (IT) companies in Turkey are taken into consideration for effectiveness and performance measurement at the end of multiple time periods. To do this, we developed an alternative dynamic slack based model (DSBM) based on the slack based model (SBM) proposed by Tone (2001) and the dynamic data envelopment analysis (DEA) model proposed by Lotfi and Poursakhi (2012). The paper suggests that the alternative DSBM captures efficiency better than SBM.
