Organizational routines constitute how work is accomplished in organizations. This dissertation thesis draws on recent routine research and is anchored in the field of organization theory. The thesis consists of four separate manuscripts that contribute to related research fields such as agility or coordination research from a routine perspective while also extending routine dynamics research. Recent routine dynamics research offers a wide perspective on how situated actions within and across routines unfold as emergent accomplishments. This allows us to analyze other organization research phenomena, such as agility and coordination. Accordingly, the first and second manuscripts argue for the adoption of a very dynamic perspective on routines and the incorporation of these insights into agility and coordination research. This is followed by two empirical manuscripts that expand the routine literature based on qualitative research within agile software development. The third manuscript of this dissertation analyzes how situated actions address different temporal orientations (i.e., past, present, and future). Last, the fourth manuscript addresses the performing of roles within and through routines. In general, this dissertation contributes to overall organization research in two ways: (1) by outlining and examining how agility is enacted; (2) by highlighting that actions are performed flexibly to consider the situation at hand.
