Storytelling, Narratives, Scenarios and Use Cases for Sites and Mobile

What can a user do on your site? On your iPhone app?

• When you say it in a paragraph, you have a use case.
  
  
• When you say it with conditions (if/then), you have a scenario.
  
  
• When you say it sequentially (this happens, then that happens), you have a narrative.
  
  
• When you say it across repeat visits today, and next week, integrated with social, and across all your conditions, you are telling a story.

Overly simplified? Not at all. Add wireframes and storyboards for key interactions and transitions, develop the personas: fast, lean; build; launch.

Some of the oldest stories are the simplest.
