RFP Scoring Matrix Skill

An award that can't survive a losing bidder's challenge — or a CFO's "why not the cheapest?" — wasn't really evaluated. This skill builds a weighted evaluation matrix with explicit scoring anchors, normalizes price so cost and capability are comparable, structures consensus scoring across evaluators, and stress-tests the winner before recommending an award.

What This Skill Produces

• A criteria tree (categories → sub-criteria) with weights that sum to 100%
• Scoring anchors (what a 1, 3, and 5 looks like) for every criterion
• A normalized price-scoring method so cost comparisons are apples-to-apples
• A consensus-scoring protocol for the evaluation team
• A scored comparison table and award recommendation with a weight-sensitivity check

Required Inputs

Ask for these if not provided:

• What is being sourced — category, scope, contract length, estimated annual spend
• The bidders — names or count, and their proposals or a summary of each
• What matters most — cost pressure vs. capability vs. risk vs. service, in the buyer's words
• Evaluation team — who scores (procurement, technical, quality, finance) and any mandatory pass/fail gates (certifications, financial health, compliance)
• Pricing structure — unit prices, tiers, one-time costs, so total cost of ownership can be framed

If the brief is thin, propose a default weighting and label it [assumed — confirm weights before scoring]. Never refuse to draft.

Weighting & Scoring Framework

Default category weights (adjust to the category's risk profile, then lock before opening bids):

Scoring anchors — define per criterion on a 1–5 scale before scoring: 5 = exceeds requirement with evidence; 3 = meets requirement as written; 1 = material gap or unsubstantiated claim. Never let evaluators invent their own scale mid-scoring.

Price normalization — score on comparable total cost, not headline unit price: lowest compliant bid gets 5; others scored as 5 × (lowest bid ÷ this bid). State the volume scenario used. If bids have different tier structures, price them all at the same forecast volume.

Consensus protocol — evaluators score independently first; then reconcile only criteria where scores differ by ≥2 points, discussing evidence, not averaging silently. Pass/fail gates are applied before weighted scoring — a bidder who fails a gate is out regardless of score.

Output Format

RFP Evaluation: [category / event name]

1. Scope & gates — what's being sourced, spend, and the pass/fail gates applied.

2. Criteria tree & weights — table: Category | Sub-criterion | Weight | Anchor for 5 / 3 / 1.

3. Scoring matrix — table: Criterion | Weight | [Bidder A] | [Bidder B] | … with weighted totals; price row shows the normalization math.

4. Consensus notes — criteria where evaluators diverged ≥2 points and how each was resolved.

5. Award recommendation — recommended bidder, the margin over runner-up, and key negotiation points before signature.

6. Sensitivity check — shift each category weight ±10% (rebalancing the rest): does the winner change? If yes, name the swing criterion and say the decision is weight-sensitive — flag for stakeholder alignment before award.

Quality Checks

• Weights sum to 100% and were set (or labeled assumed) before scores were assigned
• Every criterion has written anchors for 5 / 3 / 1 — no unanchored gut scores
• Price scores are normalized on total comparable cost at a stated volume scenario
• Pass/fail gates applied before weighting, with any eliminated bidders named
• Sensitivity check run — the recommendation states whether the winner is robust to ±10% weight shifts
• Recommendation is defensible to a losing bidder: every score traces to evidence in their proposal

Anti-Patterns

• Do not average unit prices across volume tiers — price all bids at the same forecast volume
• Do not set or change weights after seeing the bids — that's reverse-engineering an award
• Do not let a low price rescue a bidder who failed a mandatory gate
• Do not average away a 2-point evaluator disagreement — reconcile it with evidence
• Do not score vendor claims without evidence — an unsubstantiated "yes we can" anchors at 1–2, not 3
• Do not present an award without the sensitivity check — a winner by 0.1 points at chosen weights is a coin flip, and the readout must say so
