Ensure System Safety with GSN
GSN, or Goal Structuring Notation, is a technique to visualize how goals of a system are successively broken down into sub-goals until a point is reached where claims can be supported by direct reference to available evidence. GSN has been increasingly used for safety cases in industries such as automotive (ISO 26262), aerospace (DO-178B), rail, nuclear, and defense. If you require GSN modeling, Astah GSN is the right choice for your system safety assurances.
Astah GSN is compliant with GSN Community Standard version 1.0. As a full-fledged modeling software – not just a drawing tool – Astah GSN creates models that can be exported as SACM (ARM), the OMG standard. With Astah, you can reuse your common structures in safety case arguments, keeping your patterns consistent across diagrams.
Mind mapping is also included in Astah GSN, and your mind maps can easily be converted to GSN, making the entire diagramming process faster and easier!
Import. Export. Integrate.
Structured Assurance Case Metamodel Import & Export.
Using Astah GSN, you can import or export in the SACM (ARM) – OMG standard, allowing interoperability between systems and easy communication with other teams.
You can save GSN models in PNG, JPEG, EMF and SVG formats. You can also copy them to the clipboard, so it is easy to paste your GSN diagrams into third-party tools such as Microsoft Word.
