Abstract: 

THE FLEXIBILITY IN THE CHOICE OF WEIGHTS IS BOTH A WEAKNESS AND STRENGTH OF DEA APPROACH. IT IS A WEAKNESS BECAUSE DETERS THE COMPARISON AMONG DMUS ON A COMMON BASE. THIS FLEXIBILITY IS ALSO A STRENGTH, HOWEVER, IF A UNIT TURNS OUT TO BE INEFFICIENT EVEN WHEN THE MOST FAVORABLE WEIGHTS HAVE BEEN INCORPORATED IN ITS EFFICIENCY MEASURE, THEN THIS IS A STRONG STATEMENT AND IN PARTICULAR THE ARGUMENT THAT, THE WEIGHTS ARE INCORRECT IS NOT TUNABLE.
