Ask yourself some questions about your audience:
- Who will read/listen to this?
- How much do they already know, and what do you need to tell them?
- Why will they read/listen to what you write/say, and can you make them want to keep reading/listening?
- How do you think they'll react?
- Are you adding to ongoing research, filling in a gap in understanding, or challenging accepted ideas?
- What writing style does your audience prefer?
- Are there common ways of writing or a usual tone in your field?
The answers will affect what you write/say and how you present it.
