# LDPv2 - MVP Overview
|
||||
|
||||
## Purpose
|
||||
This MVP documentation package contains a complete breakdown of the LDPv2 project into iterative development stories following a "Walking Skeleton + Vertical Slices" approach.
|
||||
|
||||
## MVP Scope
|
||||
|
||||
The Minimum Viable Product focuses on delivering the core value proposition:
|
||||
**"Manage applications, track their deployments across environments, and maintain deployment history"**
|
||||
|
||||
### What's IN the MVP
|
||||
✅ Application management with lifecycle status
|
||||
✅ Environment management (flexible, production-ready)
|
||||
✅ Version tracking
|
||||
✅ Deployment recording and history
|
||||
✅ Current deployment state queries
|
||||
✅ Basic contact management
|
||||
✅ Business unit management
|
||||
✅ User authentication (local, JWT-based)
|
||||
✅ Basic role-based access control
|
||||
|
||||
### What's OUT of the MVP (Phase 2+)
|
||||
❌ External dependencies tracking
|
||||
❌ Data usage agreements
|
||||
❌ SLA management
|
||||
❌ Technical documentation links
|
||||
❌ Advanced reporting and dashboards
|
||||
❌ OAuth integration
|
||||
❌ Notification system
|
||||
❌ Advanced search and filtering
|
||||
|
||||
## Development Approach
|
||||
|
||||
### Phase 0: Foundation (Walking Skeleton)
|
||||
Establish the technical foundation and development patterns that will be replicated across all features.
|
||||
|
||||
**Duration**: 2-3 weeks
|
||||
**Goal**: Working authentication + 1 complete CRUD example
|
||||
|
||||
### Phase 1: Core Domain (Vertical Slices)
|
||||
Deliver business value incrementally with complete end-to-end features.
|
||||
|
||||
**Duration**: 6-8 weeks
|
||||
**Goal**: Fully functional application and deployment tracking
|
||||
|
||||
### Phase 2: Enrichment (Future)
|
||||
Add secondary features based on user feedback and business priorities.
|
||||
|
||||
## Story Structure
|
||||
|
||||

│ └── Tests (unit + e2e)
|
||||
└── Acceptance Criteria
|
||||
└── Testable user scenarios
|
||||
```
|
||||
|
||||
## Story Dependencies
|
||||
|
||||
```
|
||||
Story 0 (Foundation)
|
||||
├── Story 1 (Business Units) - Independent
|
||||
├── Story 2 (Applications) - Depends on Story 1
|
||||
├── Story 3 (Contacts) - Independent
|
||||
└── Story 4 (Environments) - Independent
|
||||
├── Story 5 (Versions) - Depends on Story 2
|
||||
└── Story 6 (Deployments) - Depends on Stories 2, 4, 5
|
||||
└── Story 7 (Current State & History) - Depends on Story 6
|
||||
```

|
||||
## Success Metrics
|
||||
|
||||
The MVP will be considered successful when:
|
||||
|
||||
1. **Functional Completeness**
|
||||
- All 8 stories are delivered and accepted
|
||||
- All acceptance criteria are met
|
||||
- Zero critical bugs
|
||||
|
||||
2. **Technical Quality**
|
||||
- Backend test coverage > 80%
|
||||
- Frontend test coverage > 70%
|
||||
- All APIs documented in Swagger
|
||||
- Code passes security audit
|
||||
|
||||
3. **User Satisfaction**
|
||||
- Users can perform core workflows without assistance
|
||||
- System performance meets requirements (<500ms API response)
|
||||
- Positive feedback from pilot users
|
||||
|
||||
4. **Business Value**
|
||||
- All applications are registered in the system
|
||||
- Deployment history is accurate and complete
|
||||
- Users prefer LDPv2 over previous tools/spreadsheets
|
||||
|
||||
## Timeline Estimate
|
||||
|
||||
| Phase | Duration | Stories |
|
||||
|-------|----------|---------|
|
||||
| Phase 0: Foundation | 2-3 weeks | Story 0 |
|
||||
| Phase 1: Core (Batch 1) | 3-4 weeks | Stories 1-4 |
|
||||
| Phase 1: Core (Batch 2) | 3-4 weeks | Stories 5-7 |
|
||||
| **Total MVP** | **8-11 weeks** | **8 stories** |
|
||||
|
||||
*Note: Timeline assumes 1 full-time developer or 2 developers working part-time*
|
||||
|
||||
## Risk Mitigation
|
||||
|
||||
### Technical Risks
|
||||
- **Database performance**: Addressed with indexing strategy in Story 0
|
||||
- **JWT security**: Implemented following best practices in Story 0
|
||||
- **Complex queries**: Deployment history queries optimized in Story 7
|
||||
|
||||
### Process Risks
|
||||
- **Scope creep**: Strict adherence to MVP scope, Phase 2 features documented separately
|
||||
- **Incomplete data**: Import tools and validation built into each entity story
|
||||
- **User adoption**: Regular demos after each story completion
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. Review this MVP overview
|
||||
2. Read the Technical Setup guide
|
||||
3. Begin with Story 0 (Foundation)
|
||||
4. Follow stories in dependency order
|
||||
5. Demo and gather feedback after every 2 stories
|
||||
|
