There are commercial tools like IBM Rational RequisitePro and DOORS that support semi-automatic change impact analysis for requirements. These tools capture the requirements relations and allow tracing the paths they form. In most of these tools, relation types do not say anything about the meaning of the relations except the direction. When a change is introduced to a requirement, the requirements...
Distributing the various phases of system development across multiple locations has posed several requirements-related challenges. These challenges directly and indirectly arise from the lack of opportunities for face to face communication and collaboration between project team members, while trying to obtain clarity on requirements. These concerns are more pronounced when the constituent sub-systems...
Understanding the relationships between requirements is important in order to understand the requirements themselves. Existing requirements management tools mainly use lists, tables, trees, and matrices to visualize requirements and their interrelations. However, all these visualization forms have a limited capability to show multiple relationships of different types. In this paper, we propose to...
A software product line oriented approach to developing systems has an impact on the development process as a whole. Although the basic idea of product lines is simple, systematic implementation of the approach is a challenging task. In fact, today's software product lines have such complex variability that their handling must be supported by tools, otherwise a systematic approach would not be possible...
The key idea of software product lines is the integrated development of a set of products, exploiting commonalities and variabilities among the products to achieve high levels of reuse. The commercial potential of this approach has already been demonstrated in numerous case studies. However, while requirements management tools are already widespread, the range of professional tool support for product...
