How do I compare vendors fairly?
Use the same time horizon, include setup and monthly costs, score each vendor against the same criteria, and separate cost from fit, support, integration effort, and risk.
Should the cheapest vendor always win?
No. A cheaper vendor can still be worse if feature fit, support, integration effort, risk, lock-in, or switching cost makes the total decision weaker.
What should I include in vendor risk?
Consider security, compliance, data ownership, uptime, contract lock-in, pricing changes, migration difficulty, roadmap risk, and exit cost.
Can I use this for software vendors?
Yes. It is built for software and service vendor comparisons where monthly cost, setup, feature fit, support, integration, and risk all matter.
