INTERACTION CENTRIC REQUIREMENTS TRACEABILITY

Requirement Traceability provides the ability to follow the life-cycle of a requirement from its evolution till subsequent refinement and use. A key issue that restricts the adaptation of approaches to create and maintain these relationships is the lack of tool support that employs a centralized repository for heterogeneous artifacts. Different artifacts are stored in different repositories and thus traceability links are expensive to maintain. Centralized repository can facilitate capturing the stakeholders interaction, which result in creation and modification of the artifacts and their relationship. These interactions hold the rationale behind changes. In this paper we propose a novel model-based CASE tool UNICASE, which aids in maintaining requirements traceability by incorporating disparate artifacts. Further, the tool facilitates capturing the evolution of requirements invoked by the informal communication in the form of discussion and comments.
