Automated Vendor Comparison and Selection Matrix

Act as a procurement specialist. Build a vendor comparison and selection framework for [COMPANY NAME] evaluating [NUMBER] vendors for [PRODUCT/SERVICE CATEGORY].

**Context:**
- Vendors under evaluation: [VENDOR 1], [VENDOR 2], [VENDOR 3], [VENDOR 4], [VENDOR 5]
- Budget range: [AMOUNT] to [AMOUNT] per [MONTH/YEAR]
- Decision timeline: [WEEKS] weeks
- Evaluation team: [NUMBER] stakeholders from [DEPARTMENTS]
- Must-have requirements: [REQUIREMENT 1], [REQUIREMENT 2], [REQUIREMENT 3]

**Deliverables (numbered):**
1. Evaluation criteria definition: [NUMBER] weighted categories (pricing [WEIGHT]%, features [WEIGHT]%, security [WEIGHT]%, support [WEIGHT]%, integration [WEIGHT]%, scalability [WEIGHT]%) with specific sub-criteria under each
2. Scoring rubric: 1-5 scale with clear definitions for each score level per criterion, eliminating subjective interpretation
3. Data collection template: standardized questionnaire for vendors covering all criteria, with required evidence/documentation for each claim
4. Weighted scoring matrix: calculate weighted scores per vendor, rank by total score, show score breakdown by category with visual comparison
5. Risk assessment: identify risks per vendor (vendor stability, lock-in, implementation complexity, hidden costs) with mitigation strategies
6. TCO analysis: 3-year total cost of ownership including licensing, implementation, training, maintenance, and scaling costs
7. Recommendation report: executive summary, detailed scoring, risk analysis, implementation timeline estimate, and final recommendation with justification

**Constraints:**
- Must include a 'do nothing / stay with current' option in the comparison
- Must flag any vendor claims that lack supporting evidence
- Must document all assumptions used in scoring
