on this evolution, and on team effectiveness. Our
results provide support for the mediating role of conflict in the relationship between the
similarity of team-TMMs at the beginning of team lifecycle and effectiveness. Our
results also provide support for the mediating role of task-TMMs in the middle of team
lifecycle between task-TMMs at the beginning of team lifecycle and effectiveness. The
results did not support our multiple mediation, and we did not find evidence for
increasing TMM-similarity over time. We move forward with some explanations.
