Coordinating Cross-Functional Feature Development

Large features require coordinated effort across frontend, backend, design, QA, and other teams. Without proper coordination, teams work in silos, integration fails, and releases slip. GitScrum provides the visibility and structure needed to orchestrate cross-functional development.

Coordination Practices

Planning Sync

CROSS-FUNCTIONAL PLANNING
═════════════════════════

PRE-SPRINT SYNC (weekly or per sprint):
├── Attendees: Tech leads from each team
├── Duration: 30-45 minutes
├── Cadence: Before sprint planning

AGENDA:
1. Feature status review
2. Upcoming dependencies
3. Blockers and risks
4. Integration points
5. Capacity alignment

OUTPUT:
├── Aligned sprint goals
├── Dependency timeline confirmed
├── Blockers assigned owners
├── Integration dates set
└── Documented in GitScrum

Daily Coordination

CROSS-TEAM VISIBILITY
═════════════════════

SHARED SLACK CHANNEL: #feature-checkout
├── All team leads joined
├── Daily progress posts
├── Integration updates
├── Blocker escalations
└── Quick decisions

Escalation Path

ESCALATION PROCESS
══════════════════

LEVEL 1: Team leads sync (same day)
├── Slack DM or quick call
├── Resolve dependency issues
└── Adjust timelines together

LEVEL 2: Engineering manager (24h)
├── Cross-team priority conflicts
├── Resource allocation issues
└── Technical disagreements

LEVEL 3: Product + Engineering leads (48h)
├── Feature scope changes
├── Major timeline shifts
└── Strategic decisions

Best Practices

For Cross-Functional Features

1. Define integration points early — API contracts before coding
2. Shared visibility — Everyone sees overall progress
3. Regular syncs — Weekly minimum, daily during crunch
4. Clear ownership — Each task has one owner
5. Celebrate together — Feature launch is team win

Anti-Patterns

COORDINATION MISTAKES:
✗ Teams work in isolation until integration
✗ No shared view of feature progress
✗ Dependencies discovered late
✗ No integration testing until end
✗ Different teams, different timelines
✗ Communication only through PM
