FORMALITY GUIDE Horse ventures need to have an exact and effectively shareable comprehension of the significance of necessities.

Why an imaginary character when there are potentially thousands of real users out there? Because, for a mass- market product, or one that is to be used by more than a dozen different people, you don’t know, and can’t get to know, all of the real users. But you can know one really well, and that imaginary user’s attributes guide your requirements: This is your persona. You don’t invent your persona, but rather derive it from market research or other surveys into your likely user population.
