A well-produced, computer-generated storyboard can also reduce the time required to produce a product specification document and production briefs, which will differ in each case for programmers, graphic artists, film crews and sound engineers but which require accurate visuals to effectively communicate specific points. As already mentioned, interactive storyboarding enables decisions to be evaluated at an early stage on screen text-fonts, screen layout, image size and resolution, andfacilitates the calculation of the file-size of the application. Once these decisions have been made and incorporated into the storyboard, storyboard screens can be output to print in expanded templates which allow briefing notes to be attached to each screen. Again the argument applies, that an integrated design approach to program modelling and documentation will benefit and speed development.
