IMS Implementation - Epic Dependencies & Critical Path

🎯 Critical Path (Must Complete in Order)

Epic 1.1 (Model Registry) ✅
    ↓
Epic 1.2 (Metrics Store) → Dec 15-18
    ↓
Epic 2.1 (ACF State Machine) → Dec 28-Jan 2
    ↓
Epic 2.2 (S_model Algorithm) → Jan 5-8
    ↓
Epic 3 (Action Gateway) → Jan 9-15
    ↓
Epic 7 (Deployment) → Feb 1-7 🚀

📊 Full Dependency Map

Tier 1 (Foundation - No Dependencies)

• ✅ Epic 1.1: Model Registry

Tier 2 (Depends on 1.1)

• Epic 1.2: Metrics Store (depends on: 1.1)
• Epic 1.3: Telemetry Bus (depends on: 1.1)
• Epic 1.4: PCR (depends on: 1.1)

Tier 3 (Depends on Tier 2)

• Epic 2.1: ACF State Machine (depends on: 1.1, 1.2, 1.4)
• Epic 2.2: S_model Algorithm (depends on: 1.1, 1.2)

Tier 4 (Depends on Tier 3)

• Epic 3: Action Gateway (depends on: 2.1, 2.2)
• Epic 4: Policy Engine (depends on: 1.4, 2.1)

Tier 5 (Depends on Tier 4)

• Epic 5: Observability (depends on: 2.1, 3, 4)
• Epic 6: Testing (depends on: 1.1-4)

Tier 6 (Final)

• Epic 7: Deployment (depends on: all previous)

⚡ What Can Run in Parallel

Week 1-2 (Dec 15-27):

• Epic 1.2 (Metrics)
• Epic 1.3 (Telemetry Bus)
• Epic 1.4 (PCR)
  ✅ All independent, can work simultaneously

Week 5-6 (Jan 9-21):

• Epic 3 (Action Gateway)
• Epic 4 (Policy Engine)
  ✅ Both depend on 2.1 but can work in parallel

Week 7-8 (Jan 22-Feb 7):

• Epic 5 (Observability)
• Epic 6 (Testing)
  ✅ Both can work in parallel

🚫 What CANNOT Be Parallelized

• 1.1 must complete before: 1.2, 1.3, 1.4, 2.1, 2.2
• 2.1 must complete before: 3, 4, 5, 7
• All Epics 1-6 must complete before: 7 (Deployment)

📅 Timeline Summary

Week	Epics	Status	End Date
1-2	1.2, 1.3, 1.4	Parallel	Dec 27
3	2.1	Sequential	Jan 2
4	2.2	Sequential	Jan 8
5-6	3, 4	Parallel	Jan 21
7	5	Sequential	Jan 27
8	6, 7	Parallel	Feb 7

🎯 Blockers to Watch

• If 1.2 delays: 2.1, 2.2 are blocked
• If 2.1 delays: 3, 4, 5, 7 are blocked
• If 3 or 4 delays: 5, 7 are blocked
• If 1-6 delay: 7 (Deployment) is blocked

✅ Go/No-Go Decision Points

Jan 2: All Tier 1-2 epics done? → Go to Tier 3
Jan 8: 2.2 done? → Can start Tier 4
Jan 21: 3 & 4 done? → Can start Tier 5
Jan 27: 5 done? → Can start 6 & 7
Feb 7: All done? → 🚀 LAUNCH

📞 Communication

If any epic is delayed >1 day:

• Update this issue with blocker
• Notify team immediately
• Assess impact on downstream epics
• Consider pulling resources from parallel work
