Goal structured notation process

A significant amount of effort has been put in the development of a graphical tool called Goal Structuring Notation (GSN). The Computer sciences department at York University have been developing this graphical tool to support safety cases in the aerospace and railway industry as it is presented in [Weaver, 2002] and [Weaver, Despotou, et. al, 2005]. Whilst there are many benefits, the tool does not provide a quantitative assessment as to how much processes influence one another.

SPEM 2.0, the process modeling language used to model the tool qualification process line. In Section 2.3, we briefly present Goal Structuring Notation (GSN), the graphical notation used to argue about process compliance.
