The twenty-one prerequisites are not a checklist to tackle in any order — they are a dependency chain. You cannot run a National Agri Exchange (#13) without trusted grading (#11), e-scales (#9), warehousing (#16) and free inter-state movement (#18) beneath it; you cannot guarantee a fair price (#14) until the exchange can discover one. Arrange them by what depends on what, and the 21 cards resolve into four layers — a build order. Start at the foundations; the capstones come last.
Illustrative — an analytical model of which preconditions logically come first, read off the prerequisites themselves, not an official sequencing. The dependency links are a reasoned interpretation, open to revision.
Foundations
Governance, identity, data and trust — the base everything stands on. These depend on almost nothing and unblock almost everything else.
Build-out
The first structures raised on the foundations — agri-zones, cooperatives, e-scales and warehousing.
Integration
Where the parts join into working systems — the national exchange, extension, credit, insurance, traceability and the public distribution system.
Capstones
The reforms that need the most beneath them — fair prices, contract farming, single-window trade and crop matching. Build these last.
Seen this way, the 21 are not a wish-list but a machine — each layer is the ground the next is built on.
