Can Zoomable User Interfaces Support Visual Requirements Specification?

Collaborative corporate requirements engineering and system specification demands modelling approaches that all stakeholders can understand and apply. Using traditional engineering methods, an IT organization often experiences frustrating communication and competency issues. Current processes lack adequate tool support for networked and complex projects. By integrating overview & detail and zooming, we implemented a means for supporting requirements specification processes with multiple stakeholders. In contrast to existing tools, we try to bridge between the disciplines by providing related modelling languages rather than setting up more boundaries through new terminologies. Our approach beats a new path towards visual specifications of requirements and the substitution of paper-based artefacts.
