Managing Feature Development Cycles
Feature development involves multiple phases from ideation through release, each requiring different activities and stakeholders. GitScrum's workflow templates, milestone tracking, and checklist features help teams create repeatable feature development processes that consistently deliver quality features on time.
Feature Development Phases
| Phase | Goal | Deliverables |
|---|---|---|
| Discovery | Validate problem | User research, data analysis |
| Design | Define solution | Specs, designs, technical plan |
| Development | Build solution | Working code, tests |
| Testing | Verify quality | Test results, bug fixes |
| Release | Deploy safely | Production deployment |
| Measure | Validate outcomes | Metrics, learnings |

Best Practices
- Define phases appropriate to your context
- Clear exit criteria between phases
- Track phase as part of epic status
- Don't skip phases even for "small" features
- Time-box discovery to avoid analysis paralysis
- Include measurement as a real phase
- Review at phase transitions for quality gates
- Iterate based on learnings from measure phase
Anti-Patterns
✗ Jumping straight to development
✗ Skipping discovery for "obvious" features
✗ No measurement after release
✗ Phases without clear exit criteria
✗ Testing as afterthought
✗ No phase visibility in tracking
