Influence of the project manager's personal characteristics on project performance

The purpose of this study is to analyse the project manager's personal characteristics in relation to its effects on project performance using an empirical survey of 244 project managers. The results show that skills, knowledge and attitudes directly affect project performance and that personality traits do not have direct effects, but indirectly affect attitudes. The results also show that certification in project management does not directly affect project performance but has a moderating effect on the relationship between the project manager's skills and knowledge and project management performance.
