本研究樣本為由3人或4人組成的49組團隊，利用T檢定、迴歸分析、相關分析的統計分析方法，研究結果顯示，團隊中加入新成員會使決策流程滿意度改變，決策流程滿意度對團隊績效亦有影響，此外，衝突與決策流程滿意度之間也有相關性存在。 Since the environment of an enterprise changes rapidly nowadays, personnel change or turnover has become a normal event in organizations. There are two schools of thoughts in organizational behavior with regard to the influence of newcomer in organizations, namely a positive and a negative side. Theorists holding the negative opinion consider that, socializing newcomers may disperse the energy of old timers and make old timers less able to focus on the task. As a result, it may lead to a lower satisfaction toward both the group decision-making process and the group performance. In contrast, theorists with the positive thinking believe that newcomers may help promote a higher satisfaction toward the group decision-making process and performance due to the fact that newcomers may bring in different ideas, opinions and/or suggestions.
The present study under a laboratory setting was intended to find answers to the following three research questions: 1) whether there was any differences between the control and the experimental groups in terms of their satisfaction toward the group decision-making process, perceived conflicts, and the group performance; 2) which of the following factors contributing the most toward the group performance: group gender composition, members perceived conflicts, and perceived satisfaction; and 3) whether there existed any correlation between perceived conflicts and perceived satisfaction of the group decision-making process.
Based on a sample of 49 teams with three or four persons per team (totally164 participants), the present research had the following findings. Using a T-test, a correlation analysis and a regression analysis, findings of the study revealed that newcomers did produced a different satisfaction toward the group decision-making processes; satisfaction of the group decision-making process would contribute the group performance; and there were indeed some correlations between satisfaction of the group decision-making process and members perceived conflicts.
