- ItemOpen AccessCHANGE AWARENESS IN SOFTWARE ENGINEERING USING TWO DIMENSIONAL GRAPHICAL DESIGN AND DEVELOPMENT TOOLS(2000-10-19) Tam, James; McCaffrey, Lorin; Maurer, Frank; Greenberg, SaulIn this paper, we discuss several display mechanisms for representing changes in the UML (Unified Modeling Language) class diagrams: animated replays, storyboards, iconic representations and a documentation method. These display mechanisms were implemented in a prototype UML editor. We present the results of an empirical interface refinement study that was conducted to determine the strengths and weaknesses of the four change display mechanisms. The results show some preference for the symbolic presentation of changes, specifically that most study participants liked the documentation method best. Qualitative result summaries are given for documentation and the other mechanisms.
