Presentation professor Andrew Abela suggests you use these types of evidence in your board room presentations:
- Causal - indicate what caused the situation
- Authorities - refer to a well-known or established authority(ies) who agrees with your position
- Consistent - show how your evidence lines up with actions your audience has taken previously
