Requirements in the 21st Century: Current Practice and Emerging Trends

Authors: Sean Hansen, Nicholas Berente, and Kalle Lyytinen

Published in: Dagstuhl Seminar Proceedings, Volume 8412, Perspectives Workshop: Science of Design: High-Impact Requirements for Software-Intensive Systems (2009)


Abstract
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.

Distributed Cognition in the Management of Design Requirements

Authors: Sean Hansen and Kalle Lyytinen

Published in: Dagstuhl Seminar Proceedings, Volume 8412, Perspectives Workshop: Science of Design: High-Impact Requirements for Software-Intensive Systems (2009)


Abstract
In this position statement, we outline a new theoretical framework of the distribution of design requirements processes. Building upon the Theory of Distributed Cognition, we characterize contemporary requirements efforts as distributed cognitive systems in which elements of a design vision are distributed socially, structurally, and temporally. We discuss the various forms of distribution observed in real-world systems development projects and the processes by which representational states are propagated through the system. We conclude with a brief discussion of the implications of the framework for requirements research and practice.

The Case SIS Project: An Enterprise System in Higher Education

Authors: Sean Hansen and Kalle Lyytinen

Published in: Dagstuhl Seminar Proceedings, Volume 8412, Perspectives Workshop: Science of Design: High-Impact Requirements for Software-Intensive Systems (2009)


Abstract
In 2006, Case Western Reserve University (Case) initiated the acquisition,  customization, and implementation of a new student information system (SIS).   The Case SIS Project was intended to integrate the capture and management of  all student information and student-facing administrative functions  across the university’s distinct schools. Key functions supported by the  platform include admissions, financial aid, course selection and enrollment,  grading, degree tracking, and transcript management. The initial roll-out of  the system was completed in the Fall 2008 semester, and additional phases will  be rolled out over the course of the 2008 - 2009 academic year.

The Summit County Integrated Public Safety Initiative: Information Sharing in Law Enforcement

Authors: Sean Hansen and Kalle Lyytinen

Published in: Dagstuhl Seminar Proceedings, Volume 8412, Perspectives Workshop: Science of Design: High-Impact Requirements for Software-Intensive Systems (2009)


Abstract
The Integrated Public Safety Initiative (IPSI) is a multi-party project  aimed at establishing effective information sharing across all members  of the law enforcement community within Sumit County in Connecticut  (on the east coast of the United States).2  A regional software vendor,  Blue Systems, Inc. (BSI), has been selected to provide the information  sharing platform that forms the core of the initiative.  In this capacity,  BSI professionals are acting as the primary managers of the overall project  effort.  The project is envisioned as a multi-year effort, with the  four central law enforcement entities in the county adopting the system in  2008 and additional public safety entitiesmigrated onto the platform over  the next three (3) years.
