Trade Study Workflow (with mandatory gates):

□ Step 1: Define Problem Statement
  └─ GATE: User confirms problem statement text

□ Step 2: Conduct Root Cause Analysis  
  └─ GATE: User confirms root cause identification

□ Step 3: SOURCE REGISTRATION
  └─ GATE: User provides/confirms available sources

□ Step 4: Collect Alternative Data
  └─ GATE: User confirms alternatives list and data

□ Step 5: Define Evaluation Criteria
  └─ GATE: User confirms criteria definitions

□ Step 6: Assign Criteria Weights
  └─ GATE: User confirms weight assignments

□ Step 7: Normalize Data
  └─ GATE: User confirms normalization approach

□ Step 8: Score Alternatives
  └─ GATE: User confirms scoring method

□ Step 9: Perform Sensitivity Analysis
  └─ GATE: User confirms sensitivity parameters

□ Step 10: ASSUMPTION REVIEW
  └─ GATE: User approves all documented assumptions

□ Step 11: SELECT OUTPUT DIAGRAMS
  └─ GATE: User selects which visualizations to include

□ Step 12: Generate Report
  └─ GATE: User approves final report

📚 SOURCE REGISTRATION
═══════════════════════════════════════════════════════════════════════════════

Before proceeding, I need to establish the source documents for this analysis.

AVAILABLE SOURCE TYPES:
  [A] Product Datasheets (specifications, performance data)
  [B] Test Reports (measured performance, validation results)  
  [C] Prior Trade Studies (historical analyses, lessons learned)
  [D] Requirements Documents (system requirements, constraints)
  [E] Cost Estimates (pricing, TCO analyses)
  [F] Standards/Specifications (compliance requirements)
  [G] Expert Inputs (documented SME assessments)
  [H] Other (describe)

CURRENT REGISTERED SOURCES: [None]

───────────────────────────────────────────────────────────────────────────────
REQUIRED ACTIONS:

1. Which source types do you have available? [List letters]

2. Please provide/upload the source documents, OR describe each source:
   - Document name:
   - Document type:
   - Date/version:
   - Relevant sections:

3. Are there sources you need but don't have? [Y/N]
   If Y, I will flag data gaps requiring these sources.

───────────────────────────────────────────────────────────────────────────────
⚠️  I cannot proceed with analysis until sources are registered.
    All analysis outputs will reference these registered sources.
