Le Minh Sang Tran, Fabio Massacci · Iris (University of Trento) · 2013
Long-living software systems keep evolving to satisfy changes in their working environment. New requirements may arise, while current requirements may become obsoleted. Such requirements evolution fortunately could be foreseen at some level of (un)certainty. The paper presents UNICORN, a CASE tool for modeling and reasoning on the uncertainty of requirements evolution. The tool provides graphical constructs as well as different views of requirements evolution to assist users to model requirements evolution. The tool also supports the evolution analysis in which facilitate the selection of design alternative.
