Abstract
Personal competence relates to individual skills in coping and handling themselves through situations. The ignorance of personal competence awareness among team members within the industry often leads to the project's failure and coupled with limited studies on how personal competence influence project success within the construction industry. Hence, the needs for further investigation on the effect of personal competencies on project success among Selangor construction firms. A cross-sectional survey of 107 questionnaires was administered to respondents from G7 construction firms within Selangor. The Smart PLS-SEM software version 3.0 was used in analysing the data. The findings show that both self-awareness and self-management are positively significant with project success among Selangor construction firms, providing more understanding of how personal competence influences project success among Selangor construction firms. The implications and suggestions for future study are discussed, which could serve as a useful reference point for further research in construction project management.
