Scenario-Based Analysis of Software Architecture

Rick Kazman, Gregory Abowd, Len Bass, Paul Clements

November 1996

Software architecture is one of the most important tools for designing and understanding a system, whether that system is in preliminary design, active deployment, or maintenance. Scenarios are important tools for exercising an architecture in order to gain information about a system’s fitness with respect to a set of desired quality attributes. This paper presents an experiential case study illustrating the methodological use of scenarios to gain architecture-level understanding and predictive insight into large, real-world systems in various domains.
