All six hypotheses were accepted, indicating that success is influenced by information quality, ease of use, perceived usefulness, user satisfaction, and system dependency. The strongest impact was observed in user satisfaction, while the weakest was in information quality. These findings provide empirical insights for developers to enhance marketplace applications by focusing on key factors to effectively improve system success.
