First, the two orders of stakeholder management (prescriptive and relational) are relevant and should be considered by the project manager, with the prescriptive providing identification,classification and monitoring, and the relational recommending involvement and engagement. Second, the management of stakeholders of relational origin contributes positively to trust relationships, be they intuitive, integrity or competence. Third,involvement and engagement, expected of the relational order,are conducive to relationships of trust. Fourth,Hartman's(2003)typology for trust was effective in explaining the proposed model, since relevant and significant relationships were found between all three types of trust and stakeholder management. Fifth, intuitive trust is more relevant than other types, which indicates the importance of empathy and demonstration of interest in needs and expectations. This demonstration needs to be maintained after the start of the project because it is necessary to confirm and sustain trust inintegrity and competence. Last but not least, the links between the relational order and integrity trust, and between the relational order and competence trust were relevant and statistically significant, although to a lesser degree than the intuitive one. Therefore, they should not be neglected by project managers.
