Examine how competitive, outcome-based execution models like 'Challenge Mode' can address chronic delays in India's infrastructure projects. Illustrate with reference to the Modified UDAN scheme.

Chronic time and cost overruns dog Indian infrastructure: of 13 approved greenfield airports, four became operational only after 10 years and one after 20 [3]. 'Challenge Mode', introduced under the Modified UDAN scheme (approved March 2026, outlay ₹28,840 crore) [1], replaces sequential, allotment-based rollout with states competing on fixed benchmarks — a shift worth examining on both promise and limits.

How competitive execution attacks delay

• Incentive redesign: under sequential rollout a slow state lost nothing; competitive ranking makes early land handover and quick commencement a source of advantage, addressing the root cause — land acquisition and resettlement disputes [3].
• Outcome-based benchmarks: scoring on timely completion, quality, innovation and sustainability shifts scheme design from inputs released to results delivered.
• Cooperative federalism: MoUs signed with states convert the state from bystander to accountable partner — essential, since land is a state subject while funding is central.
• Capital efficiency: the Ministry targets completion in 18 months against roughly three years earlier, unlocking regional trade, tourism and cargo sooner. Using existing unserved airstrips rather than greenfield land further compresses timelines [2].

Limits the model does not cover

• The clock runs only from commencement; the longest delays occur before it, in acquisition and litigation — which is why the Standing Committee sought a land-acquisition tracking mechanism [3].
• Benchmarks reward construction, not usage. Less than 40% of routes awarded under RCS-UDAN had been operationalised [4], and routes discontinued before their three-year tenure had to be re-bid under UDAN Round 5.3 [5].
• O&M support lasts only three years (₹3.06 crore per airport annually) [2]; thereafter recurring security and fire costs fall on states.

Challenge Mode is therefore a genuine fix for the delivery stage, not the whole project cycle. Pairing it with a published greenfield–brownfield policy, a public land-acquisition tracker [3] and the Committee's recommended two-year extension of airline support [4] would convert speed of construction into durable connectivity — advancing balanced regional development under the Viksit Bharat vision.
