Extroversion Personality, Domain Knowledge, and the Creativity of New Product Development Engineers

Creativity refers to a person’s thinking of new and useful ideas at work. Drawing on the personality literature, this study proposes that employees with high extroversion personality will exchange job relevant information with colleagues to generate creativity. Drawing on the information exchange theory, this study further proposes that the effect of extroversion personality with creativity via information exchange will be stronger for workers with insufficient domain knowledge. Data collected from Taiwanese new product development engineers support our hypotheses. Previous research found that extroverted persons perform more creatively because they are more confident in their abilities. This study further demonstrates that, after controlling for self-efficacy, extroverted engineers can still think of creative ideas via exchanging information with colleagues. Although domain knowledge has been shown as crucial to creativity, few studies have explored how to stimulate creative ideas from workers with insufficient domain knowledge. This study demonstrates a useful substitute for domain knowledge, namely the extroversion personality, which may inspire creativity via exchanging information with colleagues.
