Information technology, with the recent developments towards Future Internet, creates expectations for enterprises and collaboration networks about ease of use and high business benefits. However, the benefits are not an automatic outcome of an IT system take-up. In addition to technical aspects, organizational implementation is needed, with user participation and enterprise collaboration in the process. This paper discusses the challenges and barriers of IT implementation in collaborative networks, with the aim to identify success factors for achieving the benefits. The study is based on previous research and uses the experience of collaboration business cases of COIN project (EU FP7 ICT 216256).
