Sean Hansen, Nicholas Berente, and Kalle Lyytinen. Requirements in the 21st Century: Current Practice and Emerging Trends. In Perspectives Workshop: Science of Design: High-Impact Requirements for Software-Intensive Systems. Dagstuhl Seminar Proceedings, Volume 8412, pp. 1-57, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2009)


Requirements have remained one of the grand challenges in the design of software intensive systems. In this paper we review the main strands of requirements research over the past two decades and identify persistent and new challenges. Based on a field study that involved interviews of over 30 leading IT professionals involved in large and complex software design and implementation initiatives we review the current state-of-the-art in design requirements management. We observe significant progress in the deployment of modeling methods, tools, risk-driven design, and user involvement. We note nine emerging themes and challenges in the requirement management arena: 1) business process focus, 2) systems transparency, 3) integration focus, 4) distributed requirements, 5) layered requirements, 6) criticality of information architectures, 7) increased deployment of COTS and software components, 8) design fluidity and 9) interdependent complexity. Several research challenges and new avenues for research are noted in the discovery, specification, and validation of requirements in light of these requirements features.
