Problem Statement

validation of requirements calls for stakeholder

involvement

semantic barriers of requirements models

restrict feedback during the validation

overhead through translation

REV’09 Gregor Gabrysiak, Holger Giese, Andreas Seibel

How can we fix it?

domain-specific requirements animation
leveraging formal requirements to be

tangible for end users and other stakeholders

transport the modeled content back into

the stakeholders’ domain of expertise

PROs CONs

front-end with domain specific animations still “kind of unintuitive” automation can be applied in the back-end currently, inconsistencies have to be spotted and resolved manually inexpensive validation sessions infinite iteration loop possible single and multi-user modes currently, underlying models are too static

f feedback gathered from end users
increase automation capabilities
enhance look and feel of the prototype
