Vendor Evaluation

Pick the right tool or service, negotiate fair terms, and avoid the lock-in traps. Stack-agnostic. Applies to SaaS, infrastructure providers, agencies, and any external dependency.

When to use

Selecting a tool or vendor for a new need
Evaluating alternatives to a current vendor
Build vs buy analysis
Renewal coming up: should we stay or switch?
Running a formal RFP or RFI
Comparing finalists in a vendor selection
Negotiating a contract
Assessing vendor risk (financial, security, dependency)

When NOT to use

General cost reduction (use cost-optimization)
Specific contract legal terms (those go to legal)
Performance issues with an existing vendor (try fixing before switching)
Hiring an agency for a one-off project (lighter framework needed)

Required inputs

The need (what problem are you solving, what would success look like)
Constraints (budget, timeline, integration requirements)
Stakeholders (users, IT, security, finance, legal)
Existing context (what's already used, what's been tried)
Compliance requirements

The framework: 5 phases

A structured vendor evaluation. Skip phases at your peril.
