Design how cabin crew should coordinate during a diversion to an airport passengers did not expect.

I would coordinate that response around role clarity, information discipline, and passenger triage. A diversion creates uncertainty very quickly, so the crew needs an immediate shared picture of what is confirmed, what is still changing, and which person is responsible for communicating each part of the response.

I would build the plan around short crew syncs at key moments: right after the diversion is announced, once any arrival or ground process becomes clearer, and again before deplaning or onward instructions are given. That keeps the team aligned as the situation changes instead of leaving everyone to improvise from partial information.
