Requirements traceability provides critical support throughout all phases of a software development project. However practice has repeatedly shown the difficulties involved in long-term maintenance of traditional traceability matrices. Dynamic retrieval methods minimize the need for creating and maintaining explicit links and can significantly reduce the(More)
The ability to trace new and changed requirements to their impacted components provides critical support for managing change in an evolving software system. Unfortunately numerous studies have shown the difficulties of maintaining links using traditional traceability methods. Information retrieval techniques can be used to dynamically generate traces and(More)
This paper describes a Goal Centric approach for effectively maintaining critical system qualities such as security, performance, and usability throughout the lifetime of a software system. In Goal Centric Traceability (GCT) non-functional requirements and their interdependencies are modeled as softgoals in a Softgoal Interdependency Graph (SIG). A(More)
This paper describes a technique for automating the detection and classification of non-functional requirements related to properties such as security, performance , and usability. Early detection of non-functional requirements enables them to be incorporated into the initial architectural design instead of being refactored in at a later date. The approach(More)
This paper introduces an information retrieval based approach for automating the detection and classification of non-functional requirements (NFRs). Early detection of NFRs is useful because it enables system level constraints to be considered and incorporated into early architectural designs as opposed to being refactored in at a later time. Candidate NFRs(More)
Automated traceability applies information-retrieval techniques to generate candidate links, sharply reducing the effort of manual approaches to build and maintain a requirements trace matrix as well as providing after-the-fact traceability in legacy documents.The authors describe nine best practices for implementing effective automated traceability.
The quality of audio in IP telephony is significantly influenced by the impact of packet loss rate, burstiness and distribution on audio compression techniques. On-line audio quality assessment is important to provide real-time feedback to end-to-end Internet audio transport protocols to increase the reliability and quality of the audio session. In this(More)
Dynamic trace retrieval provides an alternate option to traditional traceability methods such as matrices, hyperlinks, and manual link construction. Instead of relying upon manually constructed and maintained traces, links are generated dynamically on an 'as-needed' basis using information retrieval techniques. Prior work in this area has indicated that in(More)
