Abstract

This chapter introduces an analysis process that combines the different perspectives of system decomposition with hazard analysis methods to identify the safety-related use cases and scenarios. It argues that the derived safety-related use cases and scenarios, which are the detailed instantiations of system safety requirements, serve as input to future software architectural evaluation. Furthermore, by modeling the derived safety-related use cases and scenarios into UML (Unified Modeling Language) diagrams, the authors hope that visualization of system safety requirements will not only help to enrich the knowledge of system behaviors but also provide a reusable asset to support system development and evolution.
