A team should be:

Team types:

• enabling team
• complicated subsystem team
• platform team

Team interaction modes:

• collaboration: stream aligned teams working on the same thing together
  • increases cognitive load
  • quick
  • rhombus in diagrams
• x-as-a-service: one team provides a service to another team
  • recommend as the default mode
  • triangles in diagrams
• facilitating: one team helps another figure out how to do something
  • circles in diagrams

patterns:

• collaborating->XAAS
• XAAS->collaborating
• facilitating->no interaction
