Step 3: Story line. Write a story line covering the major elements of the presentation. It involves breaking down the theme into major components. It should be logical and not be too long; fewer than 5 topics are generally manageable. Developing a storyboard is simply breaking down the story line into its major parts or ideas. Once you have developed the storyboard, you have the basic framework of your presentation. What is then needed is to put the storyboard into slides. The basic principle is "one slide for one idea".
