NITI Aayog is the Government of India's policy think-tank, constituted under Prime Minister Narendra Modi to replace the Planning Commission. The main objective behind its creation is to increase the participation and involvement of the state governments in the economic policy-making process. It follows a bottom-up approach to planning, which is totally opposite to the Planning Commission’s traditional approach of “top-down” decision-making. One of its key mandates is to promote cooperative and competitive federalism. This was seen when the Prime Minister appointed three sub-groups of chief ministers for making suggestions in three key areas (centrally sponsored schemes, skill development and Swachh Bharat). NITI Aayog gives the states and Union Territories (UTs) of India an opportunity, which the old Planning Commission lacked, to represent their economic interests. The Prime Minister is the Chairperson of NITI Aayog.
The Union Government of India announced formation of NITI Aayog on 1 January 2015, and the first meeting of NITI Aayog was held on 8 February 2015. NITI Aayog brings together people, including experts, entrusted by the government to help shape policy on social and economic issues.
