Measuring TV Channels Efficiency; Introducing Improvements

This article aims to evaluate IRIB TV channels efficiency, using Efficiency-Measurement Method and Data Envelopment Analysis approach, and tries to offer solutions for improving their efficiency. This study employs three methodologies, i.e. Delphi Method, Causative Analysis, and Data Envelopment, to determine general indicators (input, Process, Consequence) for measuring TV channels efficiency and assessing their performance system. The popularity level of input and output factors influencing television channel's efficiency was discovered through expert's panel, and the factors influencing system performance efficiency were identified by analytical and explanatory tests. Following the collection of data and their analysis based on consecutive and pair comparisons between inputs and outputs, efficient channels subject to improvement were identified, using IRIB performance data over the last two years. The findings show that six channels were efficient and the rest needed increased or decreased level of key inputs and outputs.
