The Use Case Map (UCM) notation enables the use of graphical scenarios to model grey-box views of a system's operational requirements and behaviour, in context. The scenario traversal mechanism is the most popular UCM analysis technique but its current tool support in UCMNav is limited and hard to use, and the high coupling of its features makes it difficult to maintain and evolve. This paper presents major enhancements to the recent jUCMNav Eclipse plugin consisting of a new scenario traversal semantics accompanied by enhanced trace transformations to Message Sequence Charts. In addition, this paper identifies a set of semantic variation points which lay the groundwork for notational clarifications and user-defined semantic profiles.
