This chapter examines the relationship between team routines and temporal entrainment. While the process of entrainment generally reinforces the routines that teams follow temporal entrainment also creates opportunities for externally focused teams to change their routines. Entrainment creates team rhythms that include pauses in activity that can act as triggers to change. These pauses alone are not enough to impel teams to change; managers must also employ temporal design to make use of these opportunities for change. Both the rhythms of temporal entrainment and the pauses that accompany them are part of a team's task environment. By uncovering key rhythms, as well as by managing the pauses, managers can both reinforce desired routines and change problematic ones.
