Improving object oriented analysis by explicit change analysis
Yu Liu, Siew Chee Khong, Xun Yi, Yuan Miao · 2002
Changeability is one of the major concerns in software development. Object-oriented (OO) technology itself is not enough to solve this problem. In this paper, we first discuss how the changeability issue is handled in current software development methods and what is the most important prerequisite for solving the software changeability problem. Based on these analyses, we argue that most of current OO analysis methods have missed an important activity in their analysis phase, i.e. change analysis. Thus, OO software systems developed according to these methods often cannot exhibit the expected maintainability, extensibility and reusability. In order to improve current OO analysis methods, we have proposed a conceptual framework for conducting a systematic change analysis in the software analysis phase. A detailed case study of the application of this framework in a real software project is also described in this paper.
