The purpose of this paper is to study the effectiveness of 891 branches of the large commercial Greek bank for the three months December 2013-February 2014, using the method of Data Envelopment Analysis (DEA). One of the interesting aspects of this work is the ability to divide the branches into potential groups in order to understand and measure the efficiency of each group separately. Two Data Envelopment Analysis models have been used in this research whereby the criteria used to divide the branches were: 1) the proximity of the branches to the capital city of each province( central and non-central branches) and 2) the ability of the branch to issue or grant all categories of loan products such as mortgages, consumer and corporate. Variable Returns to Scale (VRS) , Input /Output Orientation, model results are presented for analysis.
