This research explores the influence of personality types on ERP system learning performance. Four personality types were identified using cluster analysis based on the Big Five personality traits, i.e., conscientiousness, neuroticism, extraversion, openness, and agreeableness. These four personality types were found to be significantly associated with ERP learning performance. Additionally, prior knowledge, learning motivation, demographic factors (such as gender, age, year in school), and social as well as culture influences were found to moderate the relationships between the personality types and ERP learning performance. These findings can provide valuable insights for the organizational success of ERP systems by helping to identify which users can learn to utilize these systems effectively.
