Portfolio: PowerPoint PowerPoint is one of the more commonly used presentation mediums, yet it tends to be used in the the most amateurish way. Executives understand the value of dressing according to their role, yet their presentation material, and that of the representatives, often fails to speak of the same excellence. The quality of a presentation can and does make a difference. Excellent PowerPoint presentations 'wow' an audience, hold their attention and help you to close your deals. An image speaks a thousand words.
