Overview

Vendor selection process: requirements definition, market survey, RFI (gather basic capability information), RFP (detailed requirements and pricing), evaluation (score proposals), proof of concept, and selection.

Key Concepts

RFI: Gather basic capability information to qualify vendors. RFP: Detailed requirements and pricing request. Evaluation criteria: Weighted criteria for scoring proposals. PoC: Testing vendor solutions in your environment.

Best Practices

Define evaluation criteria and weights before issuing the RFP. Include a PoC requirement for significant investments. Conduct reference customer conversations. Document the selection rationale.

Key Considerations

Vendor selection processes can be gamed — vendors optimize proposals for stated criteria. PoC testing in your environment reveals issues that lab tests miss. References provided by vendors are selected for positive experiences.
