Why?
Breaking down silos
Teams communicate because they have to in order to succeed in their joint mission
Creating crew motivation
Leave room for the leadership of team members... while maintaining control and communication.
Reinforcing psychological safety
And so free up initiative, commitment and desire to help each other.
Establishing internal governance
Where is the information, and who decides? Hierarchical or field decision?
Building a culture of responsibility
Move from "what are my orders?" to "I intend to...".
