As a goal of Iranian governmental vision in 2020, the total productivity share of all Iranian sectors must be reached to 31.3% of GDP (at least). All the efforts and infrastructure should be developed in order to meet this goal. For this purpose a research project has been defined in National Iranian Gas Company (NIGC) for productivity measurement of Technical Inspection departments and the BSC-DEA model has been developed in order to measure productivity using Productivity Monitoring System (Multi-Performance Objectives). The finding of this project (which is still under development) is presented in this paper. The MADM methods are applied to choose the proper KPIs of performance objectives. The BSC approach which is applied in this project provides a methodology to determine the KPIs .Developing productivity monitoring system using DEA method will be a useful tool for further steps of continues improvement.  Application of this approach is illustrated by a case study in NIGC Technical Inspection department.
