Strategy is action in space and time. It is impossible to conceive of strategic behaviour outside of time, and the management of temporal factors plays a substantial role in determining the path and outcome of conflict. Yet time’s role in strategy has been empirically under-studied and theoretically neglected by scholars. This paper addresses this by identifying four constituent concepts of time for strategists: Order, Duration, Significance and Transition. The paper explores how each applies to and can improve our understanding of strategic behaviour. The paper concludes by outlining some of the promising avenues of policy opportunity and scholarly research.
