Acceptance of Necessity
In one line: An Acceptance of Necessity (AoN) is the DAC's in-principle 'yes, we need this', and it opens the formal buying process.
What it does
AoN accepts a capability requirement and sets the route of purchase. Only after it can the service issue a request for proposal to vendors. Then come technical evaluation, trials, comparison of offers, price negotiation, financial approval and finally the contract.
What it does not do
It does not commit the full amount, select a vendor or sign a deal. A headline figure like ₹2.12 lakh crore is the estimated value of accepted needs, not money spent. Some AoNs take years to become contracts.
Why it is in the news
The 26 October 2026 approvals were AoNs, so the real test is how many turn into contracts on time.
