Design teams for flow.
Team Topologies, from Matthew Skelton and Manuel Pais, describes four team types, each shaped to keep cognitive load manageable.
Stream-aligned
The Main Work
Owns a flow of change for a product or customer journey, end to end.
Platform
Self-Service
Provides internal services other teams use without waiting.
Enabling
Coaching
Helps other teams pick up new skills, then steps back.
Complicated subsystem
Deep Specialism
Owns a part that needs rare expertise, like a call-routing engine.
