## Epic Overview

### Business Goal
{Describe the business objective this epic achieves. What value does it deliver? Why is it important?}

{Example: "Enable project managers to visualize and manage requirements traceability across the entire software development lifecycle, reducing verification gaps by 40% and improving compliance audit efficiency by 60%."}

### Success Criteria

- {Metric 2: e.g., "Traceability matrix generation < 5 seconds"}
- {Metric 3: e.g., "User satisfaction score ≥ 4.5/5"}
- {Metric 4: e.g., "Zero critical bugs in production for 30 days post-launch"}

### Scope
**In Scope:**
- {Feature 1: e.g., "CRUD operations for requirements"}
- {Feature 2: e.g., "Bi-directional traceability links"}
- {Feature 3: e.g., "Visual graph representation"}

**Out of Scope:**
- {Exclusion 1: e.g., "AI-powered auto-linking (deferred to v2)"}
- {Exclusion 2: e.g., "Integration with Jira (separate epic)"}
- {Exclusion 3: e.g., "Mobile app support"}

### Target Users
- {User Persona 1: e.g., "Project Managers managing 100+ requirements"}
