Critical Path Duration: 10-12 days Longest Sequential Chain:
- Infrastructure (✅)
- API Contract (2h)
- FastAPI Setup (3h)
- Database Models (4h)
- License Endpoints (7h) - waits for KMS + Identity Platform
- JWT Validation (4h)
- Comprehensive Tests (4h)
- Deploy to GKE (4h)

Key Insights from Dependency Analysis
1. True Parallelization Windows
Day 1 (Maximum Parallelization):
- 4 agents working simultaneously
- 5 tasks executing in parallel
- 12 hours of work compressed into 4-hour window
- Speedup: 3x faster than sequential
Day 2-3 (High Parallelization):
- 3-4 agents working simultaneously
- 4-5 tasks executing in parallel
- 10 hours of work compressed into 4-hour window
- Speedup: 2.5x faster than sequential
Day 4-5 (Moderate Parallelization):
- 2-3 agents working simultaneously
- 3-4 tasks executing in parallel
- 8 hours of work compressed into 4-hour window
- Speedup: 2x faster than sequential
Day 6-7 (Low Parallelization):
- 2 agents working simultaneously
- 2-3 tasks executing in parallel
- Critical path dominates (deployment)
- Speedup: 1.5x faster than sequential
2. Bottleneck Tasks (Blocking Multiple Downstream Tasks)
Top 5 Bottlenecks:
- Backend Complete (Day 5) - Blocks Dockerfile build, CI/CD, Deploy
- Cloud KMS Deployed (Day 2) - Blocks KMS Integration, License Signing
- Identity Platform Deployed (Day 2) - Blocks JWT Validation, OAuth
- Database Models (Day 2) - Blocks all License Endpoints
- Deploy to GKE (Day 7) - Blocks Client SDK development
Mitigation:
- Prioritize bottleneck tasks (start early)
- Provide mocks for dependencies (e.g., mock KMS signing during development)
- Buffer time after bottlenecks for integration issues
3. Tasks with Zero Dependencies (Can Start Immediately)
Day 1 Kickoff (Parallel Start):
- Cloud KMS Module
- Identity Platform Module
- FastAPI Project Setup
- Dockerfile Skeleton
- K8s Base Manifests
- Architecture Documentation
Strategy: Assign all 5 agents on Day 1 to maximize early progress
4. Tasks with High Fan-Out (Many Parallel Opportunities)
Infrastructure Deployed ✅ → Enables 6 parallel tasks Day 1 Backend Complete (Day 5) → Enables 4 parallel tasks Day 6 Production Deployed (Day 7) → Enables 3 parallel tasks Day 9
Strategy: Ensure high fan-out tasks complete on schedule to unlock parallelization
Risk Heatmap
| Task | Complexity | Dependencies | Failure Impact | Risk Score |
|---|---|---|---|---|
| Deploy to GKE | High | 12 tasks | Blocks MVP | 🔴 Critical |
| Backend Complete | High | 8 tasks | Blocks Deploy | 🔴 Critical |
| Cloud KMS Deploy | Medium | 1 task | Blocks Signing | 🟡 High |
| Identity Platform | Medium | 1 task | Blocks OAuth | 🟡 High |
| Comprehensive Tests | High | 7 tasks | Blocks Backend | 🟡 High |
| Database Models | Medium | 1 task | Blocks Endpoints | 🟡 High |
| License Endpoints | High | 3 tasks | Blocks Tests | 🟡 High |
| CI/CD Workflow | Medium | 2 tasks | Delays Deploy | 🟢 Medium |
| Dockerfile | Low | 1 task | Delays Deploy | 🟢 Medium |
| K8s Manifests | Low | 0 tasks | Delays Deploy | 🟢 Low |
| Documentation | Low | 0 tasks | Non-blocking | 🟢 Low |
| Client SDK | Medium | 1 task | Post-MVP | 🟢 Low |
Risk Mitigation Priority:
- 🔴 Critical tasks: Allocate most experienced agents, add buffer time
- 🟡 High tasks: Daily status checks, early warning system
- 🟢 Medium/Low tasks: Standard monitoring
