Option A is correct because vendor evaluation must begin with an agreed decision framework. The organization should first define relevant criteria, measurement methods, mandatory requirements, scoring weights, acceptable evidence, and disqualification conditions. Typical criteria might cover capability, security, compliance, implementation effort, support, total cost, and contractual risk.
Vendor information can then be gathered consistently against the same framework. Claude may help extract evidence from proposals, populate a comparison structure, identify missing information, and calculate scores when the rules are explicitly defined. After the evidence has been validated, the vendors can be scored and ranked. This sequence supports fairness, traceability, and repeatability.
Options B, C, and D reverse or omit essential dependencies. Asking Claude for a recommendation without inputs invites unsupported assumptions. Scoring before defining criteria permits the desired outcome to influence the evaluation framework. Ranking before collecting evidence has no defensible analytical basis. Anthropic recommends defining specific, measurable, relevant success criteria before building evaluations. The same principle applies to vendor selection: criteria must precede measurement and judgment.
Therefore, the sound dependency chain is criteria definition, evidence collection, validation, scoring, and ranking. See Anthropic’s guidance on defining success criteria and evaluations .
