Senior executives have little time and need information quickly to make decisions. Long presentations don't work for them - they will interrupt to get to the bottom line. When presenting to executives, get to the key points like findings, conclusions and recommendations right away before other details. Stay focused on the topic they invited you to discuss and set expectations that you will spend the first 5 minutes on a summary and the rest on discussion. Create clear executive summary slides up front to boil the information down and have the rest serve as an appendix. Rehearse your presentation with someone who can provide honest feedback on how clearly and quickly your message and summary comes across.
