NEW DELHI: Premier business schools MDI Gurgaon, IIM-Ahmedabad and ISB Hyderabad and international consultancy Deloitte are in the race to conduct the first ever ' integrity index ' commissioned by India's top corruption watchdog Central Vigilance Commission (CVC) to study graft levels in 25 departments and state-run entities.Corruption in government machinery during the UPA regime was one of the election planks of Modi government in the 2014 general elections that swept the BJP into power, the first time since 1984 that a single party dominated Parliament. However, recent figures that the CVC submitted before Parliament suggest that corruption complaints have climbed to 40,517 between January and June this year as against 32,149 received during the last year. Modi government was sworn in on May 26, 2014.The integrity index would be developed for 25 major government entities and top public sector undertakings such as IOCL, ONGC NTPC , Railways, Bhel, FCI, EPFO, DDA and MCD (South), CBDT, Mumbai Port Trust, Punjab National Bank and SAIL among others.The corruption index for these public sector organisations will be based on benchmarking of governance processes by internal and external stakeholders, according to the CVC. The integrity index will help the CVC undertake a "research based approach" that can also be used by various organisations to measure them and "will evolve with changing needs.""This is for the first time such a ranking is being developed by the Commission. It will help in ensuring probity in public organisations in future," a senior CVC official told ET.The probity watchdog also hopes that the integrity index helps to create an objective and reliable tool that can measure the performance of organisations. The study will be conducted over a period 12 months and once the agreement is signed, the institution conducting the study will be required to submit a detailed report on the lines of Berlin-based Transparency International that ranked India 76th among 168 countries that it surveyed for Global corruption index.According to CVC guidelines, the selected agency will also be responsible for developing a five-year draft road map for the integrity index and its associated ecosystem. "Propose a road map for the formulation, establishment and development of process, organisatuon and structure for such measurement, advocacy and use of the scores," reads the CVC guidelines.The purpose of this study will also be to define what constitutes integrity of public organisations, identify the different factors of integrity and their inter-linkages and to validate the findings over a period of time to improve upon the robustness of the tool that measures integrity, the CVC official added.
