The Usage Scenarios document describes the set of activities that the solution will address and support. These activities are described in terms of what the user wants the solution to do and what other interfacing applications and systems need the solution to do. This information is expressed in terms of actions (functions), actors (users in a specific situation), paths (moving from one state to another within a function), conditions (what must occur to move down the path), and results (output). The Appendix contains guidelines on how to develop this information.
Use cases are an important expression of why the solution is needed and what it must do. This information is the description of how the solution must behave in the business environment to meet both business and the user’s functional needs.
