"1. Remember to whom you are giving the report. Test by pretending you are your manager and read it through his/her eyes. Is the language and detail appropriate for him/her?
2. The less information on a slide, the more visual impact the slide will have. It's fine to reveal a concept over multiple slides. Graphics are the clearest way to present statistics.
3. Include statistics from research sources to give credibility to your conclusions and recommendations, but don't make them too complex.
4. Use slide titles to more effectively communicate the exact nature of the slide.Try this test: After you think you have the final slide report finished, put it in "slide sorter' view, big enough so you can read the slide titles. Then read only the slide titles all the way through the presentation and see if they communicate the specific flow and information of your presentation. If they don't, then reorganize the slides or modify the titles.
5. If you are using a slide title more than once, use "continued" at the top of the slide.
6. Document all references on your slides, preferably at the bottom of the slide. This includes telephone conversations or e-mails you have had with experts, vendors, etc., for example: Personal communication with Dr. Harold Smith, Cornell University Medical Center, February 1, 2009.
7. Your slide report must be able to stand by itself. Your manager may use it without you being present, so you have to include all critical information on your slides or in the Notes portion of the slide. You also want your manager to feel comfortable taking your presentation to the next level of the organization."
