Each sprint includes specific testing tasks to ensure proper coverage:
| Risk | Mitigation Strategy |
|---|---|
| Complex state management | Allocate extra time for T4.1-T4.7, prioritize early in development |
| Data model complexity | Conduct thorough design reviews before implementation |
| Performance with large datasets | Implement pagination from the start, test with realistic data volumes |
| Tutorial content management | Create efficient caching strategy, consider progressive loading |
| Integration challenges | Schedule regular integration points throughout sprints |
The critical path for the MVP consists of:
Special attention should be paid to these components as delays will affect the overall timeline.
| Team Member | Sprint 1 | Sprint 2 | Sprint 3 | Sprint 4 | Sprint 5 | Sprint 6 |
|---|---|---|---|---|---|---|
| Dev 1 | Data models | Program browsing | Program details | Workout execution | Performance recording | History views |
| Dev 2 | Repositories | Exercise library | Exercise details | Tutorial content | Session recovery | Statistics |
| Dev 3 | Test data | Filtering | Search | Active workout UI | Set recording UI | Integration |
| Dev 4 | Database setup | UI components | UI optimization | State management | Error handling | Final fixes |
| UI/UX | Design support | Program/Exercise UI | Detail views | Workout flow | Recording UI | History/Stats UI |
| QA 1 | Test planning | UI tests | Integration tests | Feature testing | Recovery testing | Final testing |
| QA 2 | Test data setup | Accessibility | Performance | State testing | Data integrity | Regression |
For each task to be considered complete, it must meet the following criteria:
For each sprint, the following ceremonies will be conducted:
After completing the MVP, the following activities will be prioritized:
This implementation plan provides a structured approach to delivering the MVP of the fitness tracking application within a 12-week timeframe. By breaking down the Must-Have features into concrete tasks and organizing them into six 2-week sprints, the team can track progress and manage dependencies effectively.
The plan accounts for both functional and non-functional requirements, with appropriate time allocated for testing and risk mitigation. Regular integration points ensure that components work together as development progresses, reducing the risk of integration issues at the end of the development cycle.
