For many years, research results in requirements engineering (RE) have been developed without much interaction with, or impact on, industrial practice. Why is it so difficult to introduce RE research results into mainstream RE practice? This paper attempts to provide answers to this question by describing obstacles that researchers and practitioners have(More)
Achieving secure open and dynamic environments requires common ontologies, behavioral norms, and trust models. I nformation system security and privacy, once narrow topics primarily of interest to IS designers, have become critically important to society at large. The scope of associated challenges and applications is broadening accordingly, leading to new(More)
Research issues related to requirements modeling are introduced and discussed through a review of the requirements modeling language RML, its peers and its successors from the time it was first proposed at the Sixth International Conference on Software Engineering (ICSE-6) to the present—ten ICSEs later. We note that the central theme of " Capturing More(More)
The view is adopted that software requirements involve the representation (modeling) of considerable real-world knowledge, not just functional specifications. A framework (RMF) for <underline>requirements models</underline> is presented and its main features are illustrated. RMF allows information about three types of conceptual entities (objects,(More)
