Cross-Functional Team Management
Cross-functional teams have all the skills needed to deliver value end-to-end. Good cross-functional teams move fast with minimal dependencies. Poor cross-functional teams struggle with skill gaps and coordination. This guide covers how to build and manage effective cross-functional teams.
Cross-Functional Structure
| Aspect | Functional | Cross-Functional |
|---|---|---|
| Skills | Homogeneous | Mixed |
| Dependencies | High (external) | Low (internal) |
| Handoffs | Many | Few |
| Delivery | Component | End-to-end |

TEAM COMPOSITION
════════════════
CORE SKILLS NEEDED:
─────────────────────────────────────
For typical product team:
├── Frontend development
├── Backend development
├── Quality assurance
├── UX/Design (or close partnership)
├── Product knowledge
└── All skills to deliver
SKILL MAPPING:
─────────────────────────────────────
Map skills to people:
│ Front │ Back │ QA │ Design │
────────────┼───────┼──────┼────┼────────┤
Alice │ ★★★ │ ★ │ ★ │ │
Bob │ ★ │ ★★★ │ ★★ │ │
Carol │ ★★ │ ★★ │ │ ★ │
Dave │ │ ★★★ │ ★★ │ │
Eve │ ★ │ │ ★★★│ │
Designer │ │ │ │ ★★★ │
★★★ = Primary skill
★★ = Secondary skill
★ = Can help
TEAM SIZE:
─────────────────────────────────────
Sweet spot: 5-9 people
├── Too small: Missing skills
├── Too large: Coordination overhead
├── Can't feed with two pizzas? Too big
├── Each person adds communication paths
└── n(n-1)/2 communication paths
5 people = 10 paths
7 people = 21 paths
10 people = 45 paths
