If you are suggesting a solution, there has to be someone else who is doing things wrong (the villain). To get the audience to know why your solution is the best way to overcome the villain explain:
- What do you do?
- What problem do you solve (problem created by the villain)?
- How are you different (from the villain)?
- Why should I care about your solution?
