Modeling and Tracing Stakeholders' Goals across Notations using RE-Tools

The ability to represent stakeholders’ goals and their operationalizations, through tasks, resources, system requirements and specifications, helps better ensure that the projected system meets its intended goals. To offer such an ability, various notations have been developed, but somewhat independently of each other, each for its own concepts and with its own tool. As a result, it is difficult to establish end-to-end traceability among the various concepts. This paper presents RE-Tools a toolkit towards an integrated modeling of such concepts, using i*, the NFR framework, KAOS and Problem Frames. RE-Tools uses a meta-model approach to representing and integrating the notations, which includes shared, generalized meta-classes and cross-notational goal achievement contribution links. This approach is intended to allow for a uniform application of the Label Propagation Procedure in determining goal achievement across the supported notations, using either the open or closed world assumption. 1 General Information Name RE-Tools[1] Version 2.0 Information http://www.utdallas.edu/~supakkul/tools/RE-Tools Frameworks i* [2], NFR Framework [3], KAOS [4], Problem Frames [5], UML Purposes Modeling and reasoning support, foundation for other tools [6] Features Integrated modeling environment, automated and integrated Label Propagation Procedure using open or closed world assumption, UML Profile-based meta-model, navigatable inmemory models, interchangeable XMI/XML file format, extension via plug-in and APIs, open-source, Windows OS supported.
