Great article. Knowing which questions to answer, how to answer them and what questions will be asked next because of the answers you give - sounds like leadership.

Urgent answers are only demanded:
  - in an emergency.
  - by people who don't have the authority to function without permission.
  - by people too scared to take responsibility.
  - by people selling you something.

The first is acceptable. Two and three are indications where leadership can be strengthened. As the leader you can give them the authority or the courage to make this and future decision themselves.

You left off the answer that trumps them all - DENNY CRANE.
