Special invitees to the Aayog are Road Transport and Highways Minister Nitin Gadkari, Social Justice and Empowerment Minister Thawar Chand Gehlot, Railways and Commerce Minister Piyush Goyal, and Minister of State (Independent Charge) for Statistics and Programme Implementation Rao Inderjit Singh.
Niti Aayog is the premier policy think tank of the government and provides both "directional and policy inputs".
While designing strategic and long term policies and programmes for the Central government, it also provides relevant technical advice to the Centre and states. The Aayog was set up in 2015 after replacing Planning Commission, a vestige of the socialist era.
