A scheme notified in Delhi is half a scheme; the other half is the state's adoption, the state-level concurrence, and the implementing architecture that determines whether it lands.
India is a Union of States, and the operational reality of most regulatory and policy outcomes is determined by where the implementing authority actually sits. Centrally Sponsored Schemes require state-level matching, state-level allocation, state-level disbursement; the Centre designs, the state delivers. The GST Council operates as a constitutional body where the Centre and states sit as co-equal participants. The state-level investment promotion architecture, the State Industrial Investment Corporations, the state-level approvals for land, water, electricity, environment, the state government's posture on a Centrally announced scheme, all determine whether a Centre-level commitment translates into a project on the ground.
