This study explored what factors influence on, or covary with perspective diversity through the questionnaire survey of business planners who were engaged in projects regarding new business, products, or services (n=400). The results revealed that perspective diversity was influenced by diversity of team members in the dimension of required skills and demographics. The diversity of representation used for communication, diversity of thinking styles (e.g., analogical thinking), and diversity of contacts outside team covaried with perspective diversity. It is suggested that diversity of team member indirectly increased perspective diversity mediated by diversity of contacts outside team.
