of this study is to investigate the stakeholder conditions which are suggested in three parts;
stakeholder impact, stakeholder engagement, and stakeholder psychological empowerment on
project success. The data obtained from a questionnaire survey administered to 197 respondents
for initial research, 204 for main research, and 5 construction companies for validation research
by using structural equation modeling (SEM) with program AMOS 16. The results indicated
that stakeholder psychological empowerment applying of the ability to perform has a significant
influence on project success measured by quality performance. On the other hand, stakeholder
engagement reflected by engagement scope has no significant influence on project success.
