Within the scope of this project, the ZEW conducted a survey with roughly 200 IT-experts and persons in charge from the information systems of companies of the manufacturing industry and selected service industries with more than 100 employees in Germany. The survey focused on the development of prices for IT components and the current IT-trends. The experts were asked to provide their assessment of the development of prices for various IT components for the next twelve months. On the basis of the acquired data, the IT-trend index and three partial indexes (interoffice communication, data bases and SAP applications, data centre) were calculated. In addition, the experts were asked to evaluate the development of the relevance of IT-trends.The results of the two survey waves are summarized in the respective IT-Trendreport:IT-Trendreport 2009 (only available in German)IT-Trendreport 2008 (only available in German)
