Discuss the importance of navigation slides when in a long or complex presentation

What will be an ideal response?

To tell your audience where you're going and where you've been, you can use a series of navigation slides based on your outline or agenda. This technique is most useful in longer presentations with several major sections. As you complete each section, repeat the slide but indicate which material has been covered and which section you are about to begin. This sort of slide is sometimes referred to as a moving blueprint. You can then use the original slide again in the close of your presentation to review the points you've covered. As an alternative to the repeating agenda slide, you can insert a simple bumper slide at each major section break, announcing the title of the section you're about to begin.
