The Five-Year Plans were laid to rest by the Narendra Modi-led NDA government in 2015. Hence, the 12th five-year plan is considered the last five-year plan of India. The decades-old Five-Year Plans was replaced by a three-year action plan, which will be part of a seven-year strategy paper and a 15-year vision document. The Niti Aayog has replaced the Planning Commission in the Modi Cabinet and launched three-year action plans from April 1, 2017, onwards.
