A Lightweight Methodology for Safety Case Assembly [chapter]

2012 Lecture Notes in Computer Science  
We describe a lightweight methodology to support the automatic assembly of safety cases from tabular requirements specifications. The resulting safety case fragments provide an alternative, graphical, view of the requirements. The safety cases can be modified and augmented with additional information. In turn, these modifications can be mapped back to extensions of the tabular requirements, with which they are kept consistent, thus avoiding the need for engineers to maintain an additional
