1. Without a mission, you can't define the work that belongs in your group and the work that doesn't belong.

2. A mission should say what you will do and help you explain what you won't do.

3. Beware of missions that promise immediate or continuous response to the organization unless you do have a 24/7/365 organization and the staff to support that service level.

4. It is easier if your manager has a mission, but if your manageer doesn't start with the work you do (and what to do) to generate your mission when your manager develops his/her.
