Module: Risks & Mitigation

Purpose​

This module provides risk assessment and mitigation strategies for stakeholder communications. It includes identified risks, impact assessment, and mitigation plans.

Use in​

  • CEO communication (risk overview)
  • CTO communication (technical risks)
  • CIO communication (operational risks)
  • Risk review meetings
  • Project planning documents

Risk Assessment Summary​

Risk Assessment Matrix​

This quadrant chart visualizes risk prioritization based on impact and probability:

Quadrant Legend:

  • Quadrant 1 (Monitor): Low impact, high probability - Monitor closely
  • Quadrant 2 (Mitigate): High impact, high probability - Active mitigation required
  • Quadrant 3 (Accept): Low impact, low probability - Acceptable risk
  • Quadrant 4 (Avoid): High impact, low probability - Avoid if possible

Overall Risk Level​

Key Risks & Mitigation​

Data Quality Issues​

Risk: Incorrect reporting due to data quality problems Impact: Medium

Likelihood: Medium (Data Quality)​

Mitigation​

  • Automated validation + quarantine layer with loop prevention (max 3 attempts: attempt_count < 3 allows retry; attempt_count >= 3 condemned, duplicate detection, circuit breaker). Human review and approval required before reprocessing condemned data.
  • Condemned layer for rows exceeding max attempts (attempt_count >= 3) or exact duplicates. Human review and approval required before reprocessing.
  • Manual review process for quarantined records
  • Data Quality Team ownership for investigation
  • Alert thresholds (quarantine rate > 5%, circuit breaker triggers, high attempt_count)

Timeline Slip​

Risk: Delayed business value delivery Impact: Medium

Likelihood: Low (Timeline)​

Mitigation (2)​

  • Phased rollout (MVP first, then production)
  • Weekly status updates, early blocker identification
  • Buffer time built into schedule
  • Clear milestone gates

Cost Overrun​

Risk: Infrastructure costs exceed budget Impact: Low

Likelihood: Low (Cost)​

Mitigation (3)​

  • Serverless architecture (pay-per-use, scales with usage)
  • Cost monitoring via CloudWatch
  • Lifecycle policies reduce long-term storage costs
  • Partition pruning minimizes query costs

Adoption Resistance​

Risk: Low usage, poor adoption Impact: Medium

Likelihood: Medium (Adoption)​

Mitigation (4)​

  • Change management program
  • Training sessions for all user groups
  • Clear benefits communication
  • Executive sponsorship

Technical Failure​

Risk: Service disruption, data loss Impact: High

Likelihood: Low (Technical Failure)​

Mitigation (5)​

  • Immutable Bronze layer (no data loss)
  • Run isolation (failed runs don't corrupt previous runs)
  • Monitoring + automated alerts
  • Safe rerun capability
  • AWS multi-AZ, 99.99% SLA

Security Breach​

Risk: Unauthorized data access Impact: High

Likelihood: Low (Security)​

Mitigation (6)​

  • IAM least-privilege access model
  • Encryption in transit (TLS) and at rest (S3)
  • Audit logs via CloudTrail
  • Prefix-scoped permissions
  • No public access (S3 bucket policies)

Compliance Violation​

Risk: Regulatory audit findings Impact: High

Likelihood: Low (Compliance)​

Mitigation (7)​

  • Immutable audit trail (Bronze layer)
  • Reproducible reporting (run_id tracking)
  • Full lineage tracking
  • Compliance review before go-live

Risk by Audience​

CEO Perspective​

  • Primary Risks: Timeline slip, cost overrun, compliance risk
  • Mitigation Focus: Phased rollout, cost monitoring, compliance review

CIO Perspective​

  • Primary Risks: Security breach, operational failure, compliance violation
  • Mitigation Focus: Security controls, monitoring, audit trail

CTO Perspective​

  • Primary Risks: Technical failure, scalability issues, team capability
  • Mitigation Focus: Architecture design, testing, team training

Stakeholders Perspective​

  • Primary Risks: Adoption resistance, process disruption, data quality
  • Mitigation Focus: Change management, training, quality processes
