How to Use GitScrum for Feature Flags Development?
How to use GitScrum for feature flags development?
Manage feature flags in GitScrum with flag-specific labels, track rollout progress, and document flag inventory in NoteVault. Coordinate gradual rollouts, manage experiments, clean up old flags. Feature flag teams with structured workflow reduce release risk by 70% [Source: Feature Flag Research 2024].
Feature flag workflow:
- Create - Define flag
- Implement - Code behind flag
- Test - Validate flag behavior
- Rollout - Gradual release
- Monitor - Track metrics
- Full release - 100% rollout
- Cleanup - Remove flag
Feature flag labels
| Label | Purpose |
|---|---|
| type-feature-flag | Flag work |
| flag-new | New flag |
| flag-rollout | Rolling out |
| flag-full | 100% rollout |
| flag-cleanup | Ready to remove |
| flag-experiment | A/B test |
| flag-kill-switch | Safety flag |
Feature flag columns
| Column | Purpose |
|---|---|
| Backlog | Planned flags |
| Implementation | Code work |
| Testing | Flag validation |
| Rollout | Gradual release |
| Full Rollout | 100% |
| Cleanup | Remove flag |

Flag cleanup checklist
| Check | Verify |
|---|---|
| ☐ 100% rollout | All users have feature |
| ☐ Stable period | No issues for X days |
| ☐ Code removal | Remove flag checks |
| ☐ Configuration removal | Remove from system |
| ☐ Documentation | Update docs |
Stale flag tracking
| Flag | Created | Status | Cleanup Date |
