Previous research shows that organisational collaboration requires coordinating work across formal and informal organizational boundaries. Previous research has also shown how such boundary-spanning across organizations come about through boundary spanners, boundary objects and boundary activities. This means that the spatial dimensions of boundary-spanning have been in focus, rather than the temporal dimensions. As time and space are connected, only focusing on the spatial dimensions provides a limited understanding of boundary management in organizational collaboration. The purpose with this paper is to develop the understanding of the spatiotemporal dimensions of boundary-spanning. We argue that attention needs to be given to the linking of individuals and artefacts, by focusing on the rhythmof activities. This we call takta. We explore the concept of takta in an empirical case, by analysing how boundary spanners, boundary objects and boundary activities were linked to each other in a rhythm involving pace, order and tempo, through takta.
