Collaborative Networked Organizations (CNOs) are increasingly com- mon in current dynamic markets. The participants in a CNO try to achieve a com- mon goal while acting on market opportunities. Information technology (IT) fa- cilitates collaboration between participants within a CNO. In this paper, we show how CNOs cope with network-dynamics related to their IT-needs. Two sub-char- acteristics of network dynamics, respectively many-to-many relations and inter- action patterns, will be investigated. In the end, we are trying to answer the ques- tion regarding what IT-needs CNOs have, to cope with CNO-dynamism. Based on a literature review we developed a framework on CNO-dynamism and exe- cuted a multi-case study within four CNOs. We conclude that all framework com- ponents are recognized within the CNOs. CNOs appeared to mainly cope with dynamics by using collaborative platforms, task management systems, and con- ference facilities.
