Jared Green CS 425 Executive Summary ANALYSIS SCENARIO A scenario is an elaboration on the user case model. A scenario will add more detail to sub-cases by describing a specific sequence of events. The user cases and the analysis scenarios together constitute the functional requirements for the system. The object of the analysis scenario is to provide enough insight to enable the development team to develop Object Interaction Diagrams. The analysis scenario is also an effective way to define the requirements of each cycle in terms of which scenarios that must be implemented. The scenarios are generated be evaluating each user case and outlining the possible variations. Each variation is documented as its own scenario. The behavior of the scenario is captured by listing the assumptions and outcomes of the scenario. Scenarios are important because they identify ways in which the system must respond in a given set of circumstances. However, it is difficult to generate assumptions because they are often implicit in the situation. The Analysis Scenario work-product is used to generate Analysis Object Interaction Diagrams, Analysis State Models and Design Scenarios. Thus it forms a vital link between the high level user cases and mid-range work products.
