The  aim  of  this  paper  is  twofold.  Firstly,  it  measures  the  relative  performance  of  six  operators  in  the  largest  Morocco’s  cities  for  the  year  of  2013.  Secondly,  it  identifies  the  potential  performance  improvements  for  the  under-performing  companies.  To  this  end,  Data  Envelopment  Analysis  (DEA)  methodology  is  applied  for  comparing  operators  according  to  three  performance  dimensions  namely;  Production efficiency, operational effectiveness and overall performance. The D.E.A results revealed that  company  operating  in  Casablanca  city  was  the  most  efficient  of  the  sample.  In  addition,  the  companies  operating  in  Casablanca  and  Marrakech  cities  are  classified,  respectively,  as  the  best  performing of the sample in terms of operational effectiveness and overall performance. Also, based on  the overall performance measure, the research outcomes identify the percentage that an underperforming  operator needs to increase its outputs or reduce its inputs in order to achieve best performance.
