Effective and efficient requirements negotiation is a key to the success of software development efforts. For large projects, this can be especially difficult to do effectively and efficiently when combining input from non-co-located experts and reaching consensus among the different stakeholders (e.g., end-users, developers, software assurance, customers) as well as among the different aspects of software requirements (e.g., functionality, nonfunctional quality, and infrastructure). Stakeholder perception conflicts about requirements issues should be identified and resolved in early stage of the project lifecycle to achieve a shared vision of the requirements. In this poster, we discuss the issues and potential solution approaches for software requirements negotiation problems through visualization. The representation of stakeholder perceptions, visualization of the perceptions, and conflict identification and resolution in the visualized perceptions are discussed.
