Early WinWin Research
The WinWin Spiral Model uses Theory W (win-win) to develop software and system requirements, and architectural solutions, as win conditions negotiated among a project's stakeholders (user, customer, developer, maintainer, interfacer, etc.). The WinWin negotiation tool is a Unix workstation-based groupware support system that allows stakeholders to enter win conditions, explore their interactions, and negotiate mutual agreements on the specifics of the new project being contracted. The model and support system also feature a central role for quantitative tradeoff analysis tools such as COCOMO®.
is a requirements definition methodology that builds on the win-win negotiation
approach and leverages collaborative technology to improve the involvement and
interaction of key stakeholders. With EasyWinWin, stakeholders move through a
step-by-step win-win negotiation where they collect, elaborate, and prioritize
their requirements, and then surface and resolve issues.
