In identifying a bias within situated learning theory towards routine work practices, this paper develops a theoretical framework for assessing the relationships between learning, sensemaking and power in the non-routine practices of temporary organising. The paper locates processes of sensemaking and learning in a model of organisational change that attempts to render power in communities of practice more visible than has been the case in theorising hitherto, by focusing on sensegiving in change projects. Change is conceived in terms of an oscillation between the routines of permanent organising and the more experimental, innovative actions of temporary organising, where leaders mobilise actors to explore new ideas. The role of sensegiving in such processes, it is argued, helps shed light on the political nature of micro-processes of change. (Contains 2 figures and 2 notes.)
