Risk Assessment

Instructions

Assess 3 risk types

Technical: Complex algorithms, new tech, performance Timeline: Unrealistic estimates, dependencies Dependency: External APIs, third-party libraries

Assessment process

1. Identify risks
2. Evaluate impact (Low/Medium/High)
3. Propose mitigation

Example

<!-- CUSTOMIZE: Replace with {{PROJECT_NAME}} domain examples -->

Plan: "Implement real-time {{FEATURE}}"

⚠️ HIGH Risk: Performance

Problem: Real-time {{FEATURE}} with high throughput is complex
Impact: May not meet latency requirements

Mitigation:
1. Start simple (Phase 1)
2. Load test early (Phase 2)
3. Optimize based on results (Phase 3)

- Mitigation:
  1. Implement tenant context middleware
  2. Add automated tests for every query
  3. Security review before launch

⚠️ MEDIUM: Database Migration on Large Dataset
- Problem: Schema change on 10M+ record table
- Impact: Downtime during migration
- Mitigation:
  1. Test on production-size dataset
  2. Use online migration strategy
  3. Schedule during low-traffic window

Timeline Risks:

⚠️ MEDIUM: Team Availability
- Problem: 2 developers on vacation during Phase 3
- Impact: 1-week delay
- Mitigation:
  1. Reschedule Phase 3 to after vacation
  2. Cross-train team members
  3. Complete critical knowledge transfer

Dependency Risks:

⚠️ HIGH: Email Service Provider
- Problem: Relying on single ESP for critical notifications
- Impact: Users miss password resets, billing alerts
- Mitigation:
  1. Add fallback ESP ({{PROVIDER_2}})
  2. Queue failed emails for retry
  3. Monitor delivery rates

---

Data Platform

Technical Risks:

⚠️ HIGH: Data Pipeline Scalability
- Problem: Current design handles 100K records/day, expecting 10M
- Impact: Pipeline crashes under load
- Mitigation:
  1. Add horizontal scaling (partition by date)
  2. Load test at 20M records/day (2x expected)
  3. Implement backpressure mechanisms

⚠️ MEDIUM: Data Quality Issues
- Problem: Source system sends malformed data periodically
- Impact: Pipeline failures, bad analytics
- Mitigation:
  1. Add comprehensive validation layer
  2. Quarantine invalid records
  3. Alert on quality threshold violations

Timeline Risks:

⚠️ HIGH: Data Source API Changes
- Problem: Upstream team planning API redesign (unknown timeline)
- Impact: Integration breaks unexpectedly
- Mitigation:
  1. Request advance notice from upstream team
  2. Build adapter pattern for easy swapping
  3. Add integration tests for early detection

Dependency Risks:

⚠️ MEDIUM: Cloud Storage Costs
- Problem: Storing 100TB+ data, costs uncertain
- Impact: Budget overrun
- Mitigation:
  1. Implement data lifecycle policies (archive old data)
  2. Use cost monitoring alerts
  3. Evaluate compression options

---

Mobile App

Technical Risks:

⚠️ HIGH: Offline-First Sync Complexity
- Problem: Conflict resolution between offline changes and server
- Impact: Data loss or corruption
- Mitigation:
  1. Use CRDT (Conflict-free Replicated Data Types)
  2. Implement last-write-wins with timestamps
  3. Extensive testing of conflict scenarios

⚠️ MEDIUM: App Store Review Delay
- Problem: Apple review takes 3-7 days, unpredictable
- Impact: Launch date uncertainty
- Mitigation:
  1. Submit 1 week before target launch
  2. Have TestFlight beta ready as backup
  3. Prepare expedited review justification

Timeline Risks:

⚠️ HIGH: Multiple Platform Parity
- Problem: Must ship iOS, Android, Web simultaneously
- Impact: 3x development effort
- Mitigation:
  1. Use React Native for code sharing
  2. Accept platform-specific features in v2
  3. Prioritize one platform for MVP

Dependency Risks:

⚠️ HIGH: Push Notification Service
- Problem: FCM/APNS outages prevent critical notifications
- Impact: Users miss time-sensitive alerts
- Mitigation:
  1. Add in-app notification fallback
  2. Implement retry logic
  3. Monitor notification delivery rates

IoT System

Technical Risks:

⚠️ HIGH: Device Firmware Updates
- Problem: Updating 10,000+ deployed devices remotely
- Impact: Bricking devices if update fails
