Research Objective and Questions

• Research Objective: Facilitate model conflict tasks with visualizations to provide an easy understanding of the given model and respective conflicts; enhance the process of solving the conflicts with relevant background information and change memory.

• Q1: “How to provide (interactive) visual means to communicate and resolve model conflicts?”

• Q1.1: “Which (EA) visualizations are scalable for large (<=1K Objects) EA models?”

• Q1.2: “Which layout algorithms are suitable to visualize EA model conflicts?”
