Presentation skills are an important part of business and require understanding your audience, planning your presentation, generating interest, delivering confidently, and answering questions. When presenting to senior management, have clear recommendations, understand your audience, make strong first and last impressions, keep it simple, perform rather than just present, handle objections, and do thorough homework including learning PowerPoint. It is important to address issues like speaking too softly or loudly, losing your place, equipment not working, or showing anger.
