Abstract

Change Impact Analysis (CIA) is typically used to identify the consequences of making a software change by utilizing the dependency and traceability information with regard to that change. Previous research highlights that CIA techniques are developed by both an understanding of interdependencies (between system components) as well as interaction of architectural modules. Given that Web systems (WS) are usually developed as a multi-tier and components based system, it is postulated that their multi-tier interaction and components interdependencies require different CIA methods. In this paper we propose extending current CIA techniques with the concept of an integrated dependency model to accommodate multi-tier and interoperability dependencies in WS.
