Short Description
The Systems Engineering and Assurance Modeling (SEAM) tool is for the modeling of assurance cases that are integrated with the models of the system, such as requirement models, functional decomposition models, and architecture models extended with fault propagations. The assurance cases are represented using the graphical Goal Structuring Notation (GSN). NASA's Reliability and Maintainability (RnM) standard is available as a GSN template to serve as a starting point for the construction of assurance cases.
