"description": "The award criteria for this procurement are defined at the ITN (Invitation to Negotiate) stage and are based on selecting the Most Advantageous Tender (MAT)-i.e. the best overall balance of quality and cost, not simply the lowest price. Overall Award Approach (MAT) * The contract is awarded to the bidder with the highest total combined score across: o Technical o Commercial (price/value for money) o Legal (terms & conditions) * Scores are weighted and aggregated to 100% to identify the winning bid. In practice: * Technical quality is usually the most significant driver. * Price/value is also critical and can be heavily weighted. * Legal compliance is smaller but can still materially impact the score. * Technical Award Criteria * Technical scoring evaluates how well the solution meets requirements and delivers value. It includes: * Core areas assessed: * Solution specification & functionality * Implementation & delivery model * Integration capability * Data & reporting * Security & compliance * User experience * Innovation & continuous improvement * Mobilisation / transition approach",
