||Nowadays, people tend to place a high value on design, studying in school of design becomes one of the popular choices for students in Taiwan. Since it is expected that there will be more and more fresh design graduates get into the design industry in the future, the way managers bring these new blood’s abilities in to full play with a view to rising performance is an important issue. Through cross-sectional study and Big Five Personality Traits (including Extraversion, Agreeableness, Neuroticism, Conscientiousness, and Openness), we selected college students studying in industrial design from Taipei as subjects to do research on the relationship between design student's personality, design performance, and group performance. In order to tap into the relationship between personality and group performance, researchers divided subjects into several teams based on their personalities and asked each team to finish few tasks, then found the most efficient team and the counterpart. On the other hand, recording subjects’ academic performances for one year facilitated researchers to understand students with different personalities’ design performances. The result indicated that: (1) the corporation between different personalities had something to do with performance. For instance, Extraversion has the best leadership than other four personalities; (2) Based on the test, the performances may decline when there were too much Extraversion who was considered as perfect leaders in the same team or lack of Agreeableness who was believed being sophisticate enough to corporate well with others; (3) Neuroticism may lower the team performance when working with other personalities except for team members who were also Neuroticism; (4) When it comes to final academic performance, Extraversion design students did better job than others; (5) Extraversion and Agreeableness made more progress on their performances; (6) Conscientiousness was drastically fewer than other four types of personalities in design industry which was worth researching on.
