Modeling and Analysis of URN Goals and Scenarios with jUCMNav

In November 2008, the User Requirements Notation (URN) was approved as a standard by the International Telecommunication Union (ITU-T). jUCMNav is the most comprehensive tool available to date that supports the definition, analysis, transformation, and management of URN requirements engineering models. URN is the first standardized framework unifying modeling concepts and notations for goals and intentions (mainly for non-functional requirements, quality attributes, and reasoning about alternatives) and scenarios (mainly for operational/functional requirements and reasoning about scenario interactions, performance, and high-level architecture). jUCMNav has been and continues to be instrumental in validating key concepts for the current standard as well as prototyping new concepts.
