Many software projects have failed because their requirements were poorly negotiated among stakeholders. This paper proposes a systematic model, called "Multi-Criteria Preference Analysis Requirements Negotiation (MPARN)" to assist stakeholders to evaluate, negotiate, and agree upon alternatives among stakeholders during requirements analysis using multi-criteria preference analysis techniques. The eight-step MPARN model is applied to requirements gathered for an industrial-academic repository system. An initial analysis demonstrates that multi-criteria preference analysis methodology with the WinWin model potentially increases stakeholders? levels of cooperation and trust by providing a systematic approach to the design of a better negotiation process, as well as focusing on unbiased aspects within a requirements negotiation.
