Software requirements negotiation using the Software Quality Function Deployment

We propose a groupware tool supporting the Software Quality Function Deployment approach to software requirements validation. The design challenge is to involve several stakeholders, having conflicting views and attitudes which may be difficult to reconcile, in the requirements validation. The adopted approach integrates collaboration and negotiation support. Negotiation models inspired the development of a set of mechanisms promoting integrative attitudes and avoiding distributive ones. Experiments with the tool revealed some usability problems, but also showed that it is convenient to use and beneficial promoting consensus.
