This paper presents a change impact analysis approach created as part of a model-driven development (MDD) environment. Its purpose is to give project stakeholders the ability to better assess the impact that requirement changes will impose on project schedule and budget. Using MDD techniques and visualization tools we were able to automate requirement change impact analysis. Therefore, the following discussion focuses on how this environment can help software project managers, developers, and other stakeholders increase their productivity and evaluate how client changes affect their daily work.
