DEA has got some features which make it an interesting and effective tool for comparing
various decision-making units in a real-life situation. For example, in the DEA method,
multiple input/output models are handled, where no assumption of a functional form relating
inputs to outputs is a must. DMUs are directly compared against a peer or combination of
peers. Inputs and outputs can have very different units. These features make DEA an effective
option for estimating ???relative??? efficiency of a DMU; it converges very slowly to ???absolute???
efficiency or ???theoretical maximum???. The limitation is that since DEA is a non-parametric
technique, statistical hypothesis tests are difficult and are the focus of ongoing research.

Services.Sectors
DEA applications have generally focused on evaluation of alternative design configurations,
performance improvement interventions, assessment of process/system performance and
benchmarking. Example application domains range from design evaluation of turbofan
jet engines (Bulla, Cooper, Wilson, & Park, 2000), circuit-board manufacturing processes
(Triantis, 2003), to process improvement intervention (Hoopes, Triantis, & Partangel, 2000)
