This paper aims at understanding the means by which EAM supports this coordination task. Informed by theory of coordination and based on empirical data (n=95) we group participating enterprises in different clusters: (1) non-coordinators, (2) dominators and (3) negotiators. We find that a similar awareness of opportunities exists in all three clusters, yet there are gaps in the realization of EAM coordination support: non-coordinators show the lowest realization, negotiators the highest. Based on this clustering and two follow-up focus groups, we provide implications about the occurrence of the clusters in enterprises and on further EAM development options.enconference paper
