Cross-Functional Dependency Mapper

I'm leading {{project_name}} which involves {{teams_involved}}. Timeline: {{timeline}}. Key milestones: {{milestones}}. I know these teams have dependencies on each other, but the current coordination is {{current_state}}. Map out:
1. A dependency graph (what team blocks what, and by when)
2. Critical path items and slack (what can slip, what cannot)
3. Handoff dates and responsible parties for each dependency
4. Early warning signals (what should trigger escalation)
5. A weekly sync structure (who needs to attend, what to unblock)
Provide a Gantt-style visual and a dependency risk register.
