However, extraverted construction project managers constitute 64% of the respondents while introverted construction project managers constitute 36%. It was revealed that the three areas where the respondents are more effective in order of ranking are effectiveness of meeting clients’ requirements in term of functionality of projects; effectiveness in terms of delivering the projects in terms of required quality standard; and effectiveness in terms of resolving conflict after occurrence before threatened project objectives which ranked first, second and third respectively. The study found out that there is a negative relationship between extraversion and effectiveness.
