Abstract:During development, requirements of software systems are subject to change. Unfortunately, managing changing requirements can take a lot of time and effort. Yet some companies show a better management of changes in requirements than others. Why? What is it that makes some projects deal with changing requirements better than others? We pursue the long term goal of understanding the mechanisms used to successfully deal with change in requirements. In this paper we gather knowledge about the state-of-the-art and the state-of-practice. We studied eight software development projects in four different companies --large and small, inclined toward structured and toward agile principles of development--, interviewing their project managers and analyzing their answers. Our findings include a list of practical (rather than theoretical) factors affecting the ability to cope with small changes in requirements. Results suggest a central role of size as a factor determining the flexibility showed either by the organization or by the software development team. We report the research method used and validate our results via expert interviews, who could relate to our findings.
