An example (and there can be many ways to do one, so keep your creativity open):

  Subject: a business meeting... where there are goals, expectations, possible impasses, as well as the possible need for a general ambiance.

  Now write down as much PRECISE detail as you want, what you're looking for related to the subject above. It can be stated in the positive or the preventative. Or you could just stream something basic via a general axis. Remember a time frame..

  And to initiate the changes you just need any kind of trigger (a check mark [✓] will do ). Make sure you've got all you want covered!
