Abstract: This paper discussed multi-effects on team adaptability of state goal orientation and interaction processes through experimental simulation method given to 66 3-person teams decision-making under change scenarios of communication interruption. According to Lewin's three-phase change model, the data were analyzed by use of HLM and step regression techniques. The results showed that learning and performance orientation have positive effects on team adaptability, Change commitment of team members have moderating effects between learning orientation and team adaptability and higher level of change commitment enhanced the influences of learning orientation on team adaptability. In different change phase, the effects of team state goal orientation and team interaction processes on team role structure adaptation were different. As the times of trail raising up the probability of higher level of team role structure adaptation increased.

Key words: team goal orientation, team adaptability, episodic change, change stage, interaction processes
