Design Research in e-Government

This paper investigates if design research in e-government should be conducted in some special way compared with standard models for design research. It reviews literature in e-government and design research in order to generate an answer to this research question. The result is affirmative that the policy character of e-government should have consequences for the way that e-government design r...

Design Principles for Research Data Export: Lessons Learned in e-Health Design Research

Information technology (IT) allows for large-scale data collection and data analysis, e.g. through logs of user behavior and online surveys. While the issue of structured access to data is extremely important, previous research has not sufficiently emphasized design of data export for research purposes. If researchers are to make their data accessible, they must be empowered to export data in a...
