Revisiting the hypotheses that supports the research which identifies the influence of stakeholder management on trust in the project environment as positive, all four hypotheses for the sample analyzed were confirmed. As is summarized in Table 4,it is possible to infer that relational stakeholder management exerts on intuitive trust, the greatest power in explaining the model, followed by integrity trust and, finally, competence trust. In the same manner, the management of stakeholders of prescriptive order exerts influence on the management of relational stakeholders, confirming what was raised in the literature research. As such, consider a relationship of proximity with Stakeholders, in particular those with significant level of power and interest in the project (Olander and Landin,2008), or with Stakeholders with power, legitimacy and urgency (Mitchell et al., 1997), and maintenance of communication throughout the project life cycle (Aaltonen, 2011;Bourne and Walker, 2005b;Missonier and Loufrani-Fedida,2014;Mok et al., 2014). Following the same line of thought, in relational stakeholder management, being empathic and concerned in considering the interests of the other party from the outset of the project is important in establishing credible relationships that, coupled with other behavior such as honoring deadlines and delivering what was contracted,establish relationships that are positive to meet the stake-holders' goals, adhering to the theoretical survey carried out(Hartmann and Hietbrink, 2013;Pinto et al., 2009;Rose and Schlichter, 2013).
