Originating from strategic management, scenario-technique yields potentials for requirements engineering. In this paper an integrated process model for such an application of scenario-technique is proposed. Flanked by an Integrated Scenario Data Model (ISDM), efficient prognosis of changes in complex requirements models is facilitated. The ISDM support this process by interlinking scenario data, requirements management data and additional data sources such as PDM/PLM systems. Scenarios are interpreted as results of interrelations among requirements. Combined with consistency assessment, the anticipation of potential future changes in requirements is facilitated, reducing potential risks for the product development process. Alongside the product development process, developers can develop reaction strategies for changes of requirements. The ISDM reduces the required effort for scenario derivation significantly by integrating data analytics and semantic modelling. In addition, the combination of process and data model allows efficient adaptations of scenarios to depict the dynamics of requirements. Intuitivism of derived scenarios is enhanced by the proposed approach.
