New non-desktop technologies may turn out to be of a more open and generic nature than traditional information technologies. These technologies consequently pose novel challenges to systems development practice, as the design, implementation, and use of these technologies will be different. This paper presents empirical material from a project where multimedia technology was introduced into a complex medical work practice (surgery). The implementation process is analyzed at the micro-level and the process is found to be highly complex, emergent, and continuous. Using actor-network theory, we argue that conceptualizing the process as cultivating the hybrid collectif of humans and non-humans, technologies and non-technologies (Callon and Law 1995) is a suitable and useful approach. This concept may capture the open-ended and emergent nature of the process and indicate the suitability of an evolutionary approach.
