By adopting a process perspective, we analyze why a project group consisting of three heterogeneous subgroups is failing to uphold such balance over time. Instead, overemphasizing cooperativeness in the early phases of the project led to over-assertiveness and escalation of group conflict. We identify three mechanisms for reinforcing dynamics. First, we find that subgroups overestimate other subgroups’ behavioral autonomy, which promotes holding simplified, negative images of each other. Second, subgroups adopt vertical disidentification when they define their own particular role. Third, cooperativeness conceals pejorative perceptions.- Reproduced Project group, Cooperativeness-assertiveness tension, Group conflict, Vertical disidentification, Image 19396 Project Management Journal CONFLICT MANAGEMENT AR 0 0 ddc 0 0 388612 IIPA IIPA 2020-11-23 51(1), 2020: p.62-76 AR124089 2020-11-23 AR
