You must determine who you are briefing and what is expected of you as a briefer. in which step of the briefing process does this activity occur?

I believe the answer is: analytic step

In briefing, analytic step includes determining the things that are necessary to fulfil and eliminate so the core message of the briefing could be well received by the audiences. This would include things such as figuring out the type of audience, figuring out the best way of delivery, and figuring out the needed equipments for the briefing.
