How to Build a Vendor Selection Scorecard
Build a vendor scorecard from verified requirements, anchored criteria, comparable demonstrations, and contract evidence instead of sales polish.
Prepare the scorecard
- Separate gates from scored criteria.
- Write low, middle, and high anchors.
- Run identical demonstrations.
- Record source and confidence beside each score.
A scorecard controls the evidence process
Criteria alone do not create fairness. Each vendor must answer the same scenario, use the same proof standard, and receive a score tied to observable performance. Undocumented roadmap promises should not score like available capability.
Procurement leverage changes later
A strong product can still be a weak choice when renewal, data export, or service remedies are unclear. Review exit terms before the apparent winner gains leverage.
Example: payroll vendors
Both vendors claim international support. One demonstrates the required country workflow and provides contract language; the other offers a roadmap slide. The scorecard distinguishes verified capability from future intent.
The decision rule
What to record before acting
Score comparable evidence, not confidence, polish, or promises that cannot be enforced.
Apply the rule in context with build an evidence register. Keep the evidence and assumptions with the decision so an outcome review can distinguish reasoning from luck.
