The first phase is the argument of choosing the best performance efficiency between two models, the Charnes Cooper Rhodes (CCR) and Banker Charnes Cooper (BCC) models to determine the efficiency score. The value of equal to one is considered efficient while anything less than one will be regarded as inefficient in which one out of those two models will be chosen based on the highest number of efficient DMUs.

According to the results of the first phase of the study, the BBC input-oriented model was chosen over the CCR input-oriented model because it has the highest number of efficient DMUs, with BBC models having eight efficient water supply systems compared to CCR models having only seven efficient DMUs.

This paper evaluates the performance of water supply systems of 14 states in Malaysia using Data Envelopment Analysis (DEA) models. The aim of the study is to compare the efficiency score between the states while suggesting the best water supply system and providing a solution to improve the current efficiency.

The value of equal to one is considered efficient while anything less than one will be regarded as inefficient in which one out of those two models will be chosen based on the highest number of efficient DMUs.
