Common Use Cases

Detect Data Silos

detector = DataSiloDetector()

# Define data sources
sources = [
    DataSource(
        id="revit",
        name="Revit Models",
        type=DataSourceType.DESKTOP_APP,
        domain=DataDomain.DESIGN,
        owner="Design Team",
        department="Engineering",
        users=["architect1", "engineer1", "engineer2"],
        data_entities=["building_model", "drawings", "schedules"],
        connections=["navisworks"],
        has_api=True
    ),
    DataSource(
        id="excel_estimates",
        name="Excel Cost Estimates",
        type=DataSourceType.SPREADSHEET,
        domain=DataDomain.COST,
        owner="Estimator",
        department="Pre-construction",
        users=["estimator1"],
        data_entities=["costs", "quantities", "labor_rates"],
        connections=[],  # No connections - silo!
        access_level="personal"
    ),
    DataSource(
        id="procore",
        name="Procore",
        type=DataSourceType.CLOUD_APP,
        domain=DataDomain.SITE,
        owner="Project Manager",
        department="Operations",
        users=["pm1", "pm2", "super1"],
        data_entities=["daily_reports", "photos", "punch_list"],
        connections=["primavera"],
        has_api=True
    )
]

analysis = detector.detect_silos(
    organization="ABC Construction",
    data_sources=sources
)

print(f"Silos detected: {len(analysis.silos_detected)}")
print(f"Connectivity score: {analysis.connectivity_score:.0%}")

Generate Silo Report

report = detector.generate_report(analysis)
print(report)

# Save to file
with open("silo_report.md", "w") as f:
    f.write(report)

View Priority Actions

print("Priority Actions:")
for i, action in enumerate(analysis.priority_actions, 1):
    print(f"{i}. {action}")

print("\nIntegration Roadmap:")
for phase, items in analysis.integration_roadmap.items():
    print(f"\n{phase}:")
    for item in items:
        print(f"  - {item}")
