This is Stage 2 of the 7-stage vendor management lifecycle. For context on the full selection-to-contract process, see our vendor contract management guide.
Why Most Vendor Selections Go Wrong
Three failure modes dominate: criteria defined after receiving proposals; price weighted too heavily at the expense of capability, risk, and relationship factors; and no scoring methodology — the person with the most authority in the room wins the argument.
The fix is simple and rarely done: define your evaluation criteria and weights before you go to market. The ISM's supplier evaluation framework emphasizes evaluating beyond price to include total cost of ownership, quality systems, delivery performance, financial stability, compliance posture, and ESG alignment — exactly the six dimensions below.
The Six Evaluation Dimensions
Define weights before going to market. These ranges reflect standard US mid-market weighting — adjust based on your specific category and risk profile.
1. Technical Capability & Fit (25–30%)

A vendor who wins your business and fails six months later hasn't solved your problem. Assessment inputs: D&B credit score trend, years in business, revenue size relative to your contract, key person dependency risk.2. Financial Stability & Reliability (15–20%)
3. Pricing & Total Cost of Ownership (20–25%)
TCO includes purchase price plus implementation, training, integration, ongoing support, upgrade cycles, and eventual replacement. Use our

For strategic, long-term relationships — this matters. How does this vendor communicate? How do they handle problems? Do their business values align with yours? Reserve heavier weighting for Tier 1 strategic vendor relationships.4. Risk & Compliance Posture (15–20%)
5. Implementation & Transition (10–15%)
6. Cultural & Strategic Fit (5–10%)
The Scoring Matrix
Score each vendor 1–5 on each criterion, multiply by the weight, and sum for a total weighted score. This example shows how two closely matched vendors can be compared objectively — preventing the highest authority in the room from overriding the data.
In this example, Vendor B scores marginally higher overall despite Vendor A scoring better on financial stability and compliance — illustrating how a weighted framework prevents any single dimension from dominating the decision.

Frequently Asked Questions
The six key dimensions are: Technical Capability and Fit (25–30%), Financial Stability and Operational Reliability (15–20%), Pricing and Total Cost of Ownership (20–25%), Risk and Compliance Posture (15–20%), Implementation and Transition Approach (10–15%), and Cultural and Strategic Fit (5–10%). Define weights before you go to market — not after receiving proposals.

Define criteria and weights before going to market.
A vendor selection scoring matrix assigns a weight to each evaluation criterion and a score to each vendor against that criterion. Multiplying score by weight gives a weighted score. Summing all weighted scores gives a total that enables objective comparison across vendors — removing subjectivity from the final decision.
Price alone is rarely the right primary criterion. Total cost of ownership — purchase price plus implementation, training, integration, ongoing support, and eventual replacement — is the correct financial lens. A vendor who wins on day-one price but underdelivers on implementation or support costs more in total.
Key inputs: D&B credit score trend, years in business, revenue size relative to your contract value (a $500K contract with a $2M-revenue vendor creates concentration risk for the vendor), key person dependency, and customer concentration (if you'd be their largest client, their financial stability is directly tied to your relationship).
