PowerPoint presentations, whether for corporate, medical or teaching use, are often doomed because of basic errors. The first error: the presentation is not well thought out, and depending on the audience, usually does not take into consideration that some viewers are either hard of hearing or have vision problems. Compounding the error, those tasked with constructing the PowerPoint presentation, have no concept of ease-of-reading color combinations.
The product logo may be on every slide, but because of vapid color combinations used through out the presentation, the viewing audience has extreme difficulty reading the slides because, at the last minute, it was decided to leave on the conference room lights!
