Act as a Senior Transportation Consultant and Supply Chain Strategist specializing in US freight optimization and carrier relationship management. I need you to create a comprehensive Carrier Selection Guide and Strategic Vetting Framework tailored to my specific logistics operation.

**SHIPPER CONTEXT:**
- Company Profile & Industry: [SHIPPER_PROFILE]
- Freight Characteristics: [FREIGHT_CHARACTERISTICS] (include commodity type, dimensions, weight, temperature requirements, HazMat status, value)
- Lane Requirements: [LANE_INFO] (origins, destinations, regional vs. national, urban vs. rural)
- Volume & Frequency: [VOLUME_DATA] (shipments per week/month, seasonality, surge capacity needs)
- Current Pain Points: [CURRENT_CHALLENGES] (reliability issues, cost overruns, visibility gaps, capacity shortages)
- Technology Stack Requirements: [TECH_REQUIREMENTS] (TMS integration needs, API/EDI capabilities, real-time tracking requirements, digital freight matching)
- Budget Parameters: [BUDGET_CONSTRAINTS] (target rate per mile, total landed cost goals, payment terms preferences)

**DELIVERABLES - STRUCTURED CARRIER SELECTION FRAMEWORK:**

**1. OPTIMAL CARRIER ARCHITECTURE**
   - Recommended carrier mix (Direct Asset-Based vs. 3PL/Broker vs. Digital Freight Platforms)
   - Mode selection rationale: TL, LTL, Intermodal, Parcel, or Specialized
   - Primary vs. backup carrier ratio recommendations

**2. VETTING & COMPLIANCE CHECKLIST**
   - FMCSA verification protocols (MC Number, DOT Authority, Operating Status)
   - Safety rating analysis (SMS Percentiles, CSA Scores, Crash Data thresholds)
   - Insurance validation requirements (Cargo limits, Liability coverage, Umbrella policies)
   - Financial stability indicators (credit checks, days to pay, equipment age/ownership)
   - Red flag detection: Double-brokering indicators, chameleon carriers, freight guard reports

**3. CAPABILITY EVALUATION MATRIX**
   - Equipment suitability (dry van, reefer, flatbed, specialized) and capacity commitments
   - Geographic coverage alignment (lane density and headhaul/backhaul balance)
   - Technology compatibility scorecard (ELD integration, API documentation, automated POD)
   - Sustainability metrics (SmartWay certification, empty mile reduction strategies)

**4. REQUEST FOR PROPOSAL (RFP) STRUCTURE**
   - Essential questions for carrier capability statements
   - Pricing model analysis: Contract vs. Spot vs. Dynamic Pricing suitability
   - Service Level Agreement (SLA) templates (Pickup/delivery windows, communication protocols)
   - Liability and claims handling procedures

**5. RISK MITIGATION STRATEGIES**
   - Lane-specific risk factors (theft corridors, weather patterns, port congestion)
   - Diversification tactics to avoid over-reliance on single providers
   - Contingency planning for carrier failure or capacity crunches

**6. IMPLEMENTATION ROADMAP**
   - 90-day carrier onboarding sequence (pilot program structure, gradual volume ramp)
   - KPI benchmarking framework (OTD%, damage/loss rates, invoice accuracy, tender acceptance)
   - Quarterly business review (QBR) agenda templates

**FORMAT REQUIREMENTS:**
- Use professional markdown with executive summary at top
- Include a comparison table contrasting Tier 1 (Premium), Tier 2 (Balanced), and Tier 3 (Budget) carrier strategies against my specific criteria
- Provide 3-5 specific interview questions I should ask during carrier discovery calls
- Flag any regulatory considerations specific to my commodity type (FDA, DOT, EPA)
