The primary goal of a project manager is to achieve desired project performance.
It is therefore of both academic and practical value to advance our understanding of how such a desired project performance can be accomplished.
This paper proposed that trust and communication are the factors contributing to the achievement of project performance. In addition, their relationship was examined by use of mediation analysis.
A total of five significant mediation models were identified.
These models reveal that trust affects communication and thus influences project performance.
In this paper, effective information flow is the versatile mediator to the trust-project performance relationship among all of these significant models.
This implies that the improvement of information flow would likely improve the achievement of project performance (i.e., achieve satisfactory and worthwhile quality in addition to maximize project time, cost, and quality).
