Abstract: Abstract The DEA technique measures efficiency in a relative manner, in that the performances of the DMUs in a group are compared with each other. The efficient ones may not be efficient when compared with the DMUs of other groups. Similarly, the inefficient ones may become efficient when compared with those of other groups. The efficiency measures for DMUs of different groups are thus not comparable.
