Collaboration: working closely together with another team X-as-a-Service: consuming or providing something with minimal collaboration Facilitating: helping (or being helped by) another team to clear impediments A combination of all three team interaction modes is likely needed for most medium-sized and large enterprises (and these modes are useful to introduce at smaller organizations sooner than many people expect). In addition, one team might use two different interaction modes for two different teams with which it works.
