In this way, with the help of DEA, a tool can be created to compare the efficiency of departments or activities of companies or organizations. Units with low efficiency are identified, and such units’ ideal (practical) efficiency is also determined. The units with the highest efficiency are identified in this section (department, department, staff). In the DEA, service units are compared according to the resources and the type of services they consume and produce. Recently, Data Envelopment Analysis (DEA) has been used to measure the effectiveness of “Not for Profit Organizations” such as government hospitals or “Non-Governmental Organizations.” In this way, the number of people employed (employed), profit (loss), capital (primary and in circulation) and the amount of production as input and the number of customers, the energy transferred, and product life as output Are used. For example, government regulators use the DEA to benchmark the performance standards of companies and industries.
