  abstract = {Defining requirements is a complex and difficult process, and defects
	in the process often lead to costly project failures. There is no
	complete and well-defined set of requirements waiting to be discovered
	in system development. Different stakeholders: users, customers,
	managers, domain experts, and developers, come to the project with
	diverse expectations and interests. Requirements emerge in a highly
	collaborative, interactive, and interdisciplinary negotiation process
	that involves heterogeneous stakeholders. At the University of Southern
	California's Center for Software Engineering, we have developed a
	series of groupware implementations for the WinWin requirements negotiation
	approach. The WinWin approach involves having a system's success-critical
	stakeholders participate in a negotiation process so they can converge
	on a mutually satisfactory or win-win set of requirements. The WinWin
	groupware system, which has evolved over four generations, enables
	and facilitates heterogeneous stakeholder participation and collaboration.
	Each generation reflects an increase in our understanding of what
	is needed for successful WinWin groupware operations and technology
	support. The authors present the major lessons they learned during
	WinWin's development.},
