Take a reorganization. A new organization chart and an FAQ can help, but they do not automatically explain why the structure is changing or how people should work within it.
Explain the problem the change is meant to solve, who made the decision, and what it means for each team’s work. Clarify what has been decided, what is still open, and where people can raise questions. Give people time to prepare wherever possible.
Then return to the explanation after the change. If the new structure was intended to clarify decisions, are people actually clearer about who decides? If responsibilities have changed again, explain why.
Transparency makes the reasoning visible and leaves room to examine whether it holds up in practice.
