SysML in Action with Papyrus uses practical examples and the open source Papyrus modeler to explore requirements, validation and the classical V cycle. The book presents a generic approach that is fully suitable to SysML, applying major system engineering principles and standards. As embedded systems are now so complex that specifying, implementing and validating requirements can no longer be expressed using only textual descriptions, this book provides a timely resource. A number of alternate notations, according to industry constraints and habits, are available. Among them one standard from the OMG: SysML.
