On the practicality of viewpoint-based requirements engineering

Requirements engineering is often characterised as the management of conflicts between the viewpoints of different stakeholders. This approach is only useful if there is some benefit in moving a specification from one viewpoint to another. In this study, the value of different viewpoints was assessed using a range of different models (ranging from correct to very incorrect), different fanouts, different amounts of data available from the domain, and different temporal linking policies. In all those models, no significant difference was observed between viewpoints.
