ISDEC is the “Innovation Systems Data – Excellence Center“ at Fraunhofer ISI. It enhances the core competences of Fraunhofer ISI that lie in the evidence-based strategic consulting of a large number of actors from politics, economy and society using a wide range of data. This includes on the one hand typical innovation indicators such as patents or publications, economic and trade data. In addition, company-specific data on the implementation of strategies and R&D measures, as well as on innovation behavior and production processes, are collected in surveys by the institute itself or together with partners. A further established data and methodological focus is model-based systems analysis, in which transformation pathways can be developed that are used as a basis for policy recommendations and strategy development. For this purpose, Fraunhofer ISI has a comprehensive set of model instruments and an associated database, which is used for various research projects at Fraunhofer ISI.
