We present an ethnographic study of the organizational aspects of the use of an electronic whiteboard (EW) system implemented in a Danish hospital located in Nykøbing Falster (NFH). The EW system had originally been developed for the emergency department (ED), but had later been extended to the entire hospital, and the study was conducted about 10 months its implementation. The study focuses on coordination regarding inter-departmental ordering of surgical operations via the EW system. The research question asked whether clinicians experienced impacts, and challenges in this respect. The results of the study show that the EW system had been configured, and the use of it organized, in a manner that facilitates support of inter-departmental coordination of work. We identify, describe and discuss the challenges related to the difficulty of accommodating the heterogeneous practices and demonstrate the complexity of organizing cooperative work using artefacts and technology across organizational units.
