The project format has become a standard and self-evident way to organize research work in today's accelerated university context, leading to the projectification of science. This paper argues that the project format is not a mere technical organizational tool, but that it challenges and reshapes research practices and ideals. The project format is embedded in a specific temporality which is called project time. The key characteristics of project time are scrutinized by distinguishing it from process time, which refers to the (...) internal organizational logic of research. In addition, project time is examined through Barbara Adam's theorizing on the commodification, control, compression and colonization of clock time. In the last part of the paper, temporal conflicts in project-based research are examined empirically by drawing upon interview material with Finnish academics working in the social sciences. (shrink)
