From subjective to objective. GRAIL ends procurement debates by replacing subjective evaluations with objective, data-backed lethality and cost-efficiency scores (CELS, TELS). This enables outcome-based acquisition for MoDs, de-risks innovation for Primes, and creates a meritocracy for innovators to win based on performance.
