NITI Aayog replaced the Planning Commission as the new government think tank in India. It will serve as an advisory body to provide strategic and technical advice to central and state governments. Unlike the Planning Commission, NITI Aayog will not allocate funds directly but will instead focus on cooperative federalism, developing a shared national agenda in consultation with states, and monitoring key government programs and policies. It has a smaller full-time staff than the Planning Commission and involves states more in planning.
