title = "Requirements development in scenario-based design",
abstract = "We describe and analyze the process of requirements development in scenario-based design through consideration of a case study. In our project, a group of teachers and system developers initially set out to create a virtual physics laboratory. Our design work centered on the collaborative development of a series of scenarios describing current and future classroom activities. We observed classroom scenarios to assess needs and opportunities, and envisioned future scenarios to specify and analyze possible design moves. We employed claims analysis to evaluate design trade-offs implicit in these scenarios, to codify the specific advantages and disadvantages in achieving requirements. Through the course of this process, the nature of our project requirements has evolved, providing more information but also more kinds of information. We discuss the utility of managing requirements development through an evolving set of scenarios, and the generality of the scenario stages from this case study.",

note = "Funding Information: This research was partially supported by the National Science Foundation, under awards RED-9454803 and REC-9554206 from the Networking Infrastructure for Education program, and by equipment from Apple Computer. A preliminary version of this paper appeared in the Proceedings of the Second ACM International Symposium on Designing Interactive Systems, August 1997, pp. 55-64 [14]. We are grateful to Matthias Jarke and Alistair Sutcliffe and to an anonymous reviewer for comments on draft versions of this paper. Funding Information: These discussions focused for the most part on nationally-articulated needs in public school (K-12) education, such as supporting collaborative, project-based learning in K-12 classrooms, increasing community involvement with schools, improving access of rural schools to educational opportunities, enhancing gender equity in science and mathematics education, and controlling material costs (Fig. 1; see also [1], [28]). We obtained a planning grant from the United States National Science Foundation (NSF), which allowed us to provide several teachers with networked classroom computers, and to continue and expand our discussion process.",
