Supplier Scorecard & Weighted Evaluation

Score competing suppliers against weighted criteria and rank them objectively — the weighted-point vendor-evaluation method taught in CPSM and CIPS. Set your weights, enter a 1–10 score per criterion, and get a defensible, audit-ready recommendation.

ISM CPSM · CIPS · Weighted-Point Model

1 Criteria, weights & supplier scores

Edit criteria names, set each weight (must total 100%), name your suppliers and rate each on a 1–10 scale. Use the critical marker in a criterion row for non-negotiable requirements such as risk or compliance.

Critical-criterion minimum 1–10

A supplier scoring below this on any critical criterion is flagged as a knock-out risk.

Weight handling

Auto-normalise rescales your weights so they sum to exactly 100% before scoring.

Total weight: 100%

Up to 5 suppliers and any number of criteria. Scores: 1 = poor … 10 = excellent for every criterion (already direction-consistent, including price — score a cheaper / better-value quote higher).

Weighted score updates instantly. Higher is better. Scale shown on a 0–10 weighted average and a 0–100 index.

📏 Based on the weighted-point / linear weighted-average supplier-evaluation model (ISM CPSM, CIPS). Figures are decision support — validate weights and scores with your sourcing team and combine with total-cost-of-ownership and audit evidence.

How the weighted supplier scorecard works

A weighted scorecard turns a subjective "gut feel" supplier choice into a transparent, repeatable number. You define the criteria that matter, decide how important each one is (its weight), score every supplier on each criterion, and the model rolls those up into a single comparable total.

The formula

For each supplier, the weighted score is the weight-share of every criterion multiplied by that supplier's score on it, summed across all criteria:

Weighted score (0–10) = Σ ( weight%_i × score_i ) ÷ 100

Because every score is on the same 1–10 scale and the weights sum to 100%, the result is itself on a 0–10 scale — multiply by 10 for a familiar 0–100 index. Each criterion's contribution is weight% × score ÷ 100, so you can see exactly which factors carried a supplier. Suppliers are then ranked from highest to lowest, and the gap to leader shows how far each one trails the top choice.

Why weights must sum to 100%

Weights express relative priority. If they don't total 100% the 0–10 scaling breaks and totals are no longer comparable. Use Auto-normalise (or the normalise button) to rescale weights proportionally to 100% without changing their ratios.

Critical-criterion (knock-out) flags

A high overall score can hide a fatal weakness. Mark non-negotiable criteria as critical and set a minimum. Any supplier below that minimum is flagged for challenge or exclusion regardless of its total.

Worked example

With weights Price 25%, Quality 25%, Delivery 20%, Service 15%, Financial 10%, Risk 5%, a supplier scoring 8/7/9/6/7/8 earns: (25×8 + 25×7 + 20×9 + 15×6 + 10×7 + 5×8) ÷ 100 = (200+175+180+90+70+40) ÷ 100 = 7.55 → a 75.5 index.

Frequently asked questions

How many criteria and suppliers can I compare?

You can compare up to 5 suppliers and add as many criteria as you need. The default six criteria — Price/Cost, Quality, Delivery/Lead time, Service/Responsiveness, Financial stability and Risk/Compliance — are the classic CPSM/CIPS set, but every name, weight and score is editable.

Should a lower price get a higher or lower score?

A higher score always means "better" on every criterion. So a more competitive or better-value price should be scored higher (e.g. 9), and an expensive quote lower (e.g. 4). Keeping all criteria direction-consistent (higher = better) is what lets the weighted sum work. For a like-for-like cost comparison, pair this with a total-cost-of-ownership or lifecycle-cost analysis first, then convert to a 1–10 score.

What if my weights don't add up to 100%?

The tool warns you and shows the running total. Choose "Auto-normalise to 100%" (or press the normalise button) to rescale all weights proportionally so they sum to exactly 100% — the ratios between criteria stay the same, so your priorities are preserved.

How do critical-criterion flags work?

Use the marker next to a criterion to make it critical. Risk, compliance and financial stability are common candidates. Any supplier below the minimum is flagged for investigation or disqualification even if its overall score looks strong.

What does "gap to leader" mean?

It's the leader's weighted score minus each supplier's weighted score. A small gap means the decision is close (worth a tie-break on price or a second round); a large gap means a clear winner.
