Synchronous text communication is becoming recognized as a valuable workplace communication medium yet some studies of group text chat indicate that its properties can lead to interactional incoherence. We consider this issue through a detailed analytic examination of text chat transcripts by showing how participants manage their interactions through considering multiple threads, turn taking and topic change. We reveal the routine practices that participants employ to create and manage coherent interaction. These practices arise from the turn taking system in operation, which facilitates straightforward repair of misunderstandings. We conclude by considering the implications of this for design and for the organisation and management of interactions of various forms.
