  abstract = {This paper investigates the effectiveness of different uses of scenarios
	on requirements discovery using results from requirements processes
	in two projects. The first specified requirements on a new aircraft
	management system at a regional UK airport to reduce its environmental
	impact. The second specified new work-based learning tools to be
	adopted by a consortium of organizations. In both projects scenarios
	were walked through both in facilitated workshops and in the stakeholders
	workplaces using different forms of a scenario tool. In the second
	project, scenarios were also walked through with a software prototype
	and creativity prompts. Results revealed both qualitative and quantitative
	differences in discovered requirements that have potential implications
	for models of scenario-based requirements discovery and the design
	of scenario tools.},
