Technique for assessing external design of software

The final version of a scenario gives an accurate view of the program through the eyes of a user. The scenario also gives management a useful view of the system. Thus the scenario becomes the first vehicle to give flow to the program externals, allowing an examination of the externals as they apply in a user environment. Anyone should be able to use a scenario to evaluate a proposed program for usability, compatibility, consistency, and completeness of functional content. The difficult job of transforming the contents of reference manuals and sample environments into task-oriented job streams need be performed and validated only once. Thus program testers, publication writers, and others can use the same scenario, rather than eah group's having to generate similar information for its pecific requirements.
