This study aimed to compare and clarify the factors which enhance capabilities of project
managers in different stages of career development. Multi‐group analysis of covariance structure
modeling were conducted by executing questionnaire survey among three groups of project managers
in different career levels: entry-level, mid-level, and senior-level. The research reached the following
conclusions. The behavior characteristics of mid-level project managers were influenced by experi-
ences of being praised. The behaviors characteristics of senior level project managers were influenced
by experiences of challenging work environments. These three groups were heavily influenced by
executing experimental learning. The behavior characteristics of these three groups were influenced
by experiences of challenging work environments and interacting with people outside workplaces
through executing experimental learning.
