<h2>5 Key Risks & Mitigations</h2> <ul> <li><strong>AI hallucination & bad data decisions</strong>: Copilot/Einstein-generated SQL miscounts, executive misjudgment, $100K-1M losses, trust collapse. Fix: AI output requires data engineer review, Semantic Layer (dbt/Cube/LookML), single source of truth, sampling verification, audit log, risk-tier approval.</li> <li><strong>Semantic Layer gaps & metric drift</strong>: "Revenue" defined differently per department, AI answers conflict, exec reports become disputes. Fix: standardize on dbt Metrics/Cube/LookML/Tableau Pulse, Data Governance Council, documented glossary, annual review, Metric Layer Tool (Transform/Trace).</li> <li><strong>Privacy / GDPR / HIPAA</strong>: PII leaks into LLM training, GDPR fines €2M+, HIPAA $1M, customer/patient exposure. Fix: Snowflake Cortex/Databricks AI (no exfiltration), private LLM, PII masking (Privacera/Immuta), SOC2/HIPAA BAA, data minimization, Data Residency.</li> <li><strong>Compute/storage cost explosion</strong>: Snowflake $10K -> $1M/mo, Databricks DBU overrun, BigQuery slot exhaustion, CFO halts spending. Fix: cost monitoring (CostQuery/Capital One Slingshot), reserved slots, auto-suspend, query optimization, materialized views, monthly budget alerts, tier workloads by ROI.</li> <li><strong>Tool sprawl & data stack complexity</strong>: Snowflake+dbt+Fivetran+Airbyte+Looker+Tableau+Power BI+Hex+Sigma = 10+ tools, unmaintainable, integration breaks. Fix: minimal modern data stack (1 DW + 1 ETL + max 2 BI), quarterly audit, "replace not add" policy, avoid vendor lock-in, adopt open standards (Iceberg/Delta).</li> </ul>
