“…First, Tone [44], Mourad et al [45], Habib [16], and Habib and Shahwan [46] confirm that DEA is a powerful non-parametric technique for analyzing the nexus between inputs and outputs. Second, Dalwai et al [47], Shahwan and Habib [48], Habib and Mourad [11], and Shahwan and Habib [49] confirm that the DEA technique delivers critical information for continual improvement. Finally, Habib and Mourad [11], Shahwan and Habib [49], Cooper et al [50], Mourad [51], and Mourad et al [52] confirm that the DEA technique focuses on the best practice concept as a base of benchmarking, that is, the relatively efficient firm (located on the efficient frontier curve), on the efficiency frontier curve, as opposed to conventional techniques that focus on central tendencies.…”
