ABSTRACT
Expeditious change is an accelerating problem for projects in most industries. In fact, a project leader becomes the key person to project success. The aim of this paper is to explore how the interpersonal skills of a project manager influence project performance. This quantitative study was conducted to test the relationship between communications and project performance. This paper also examined the effect of leadership transformation on project performance, by presenting three different characteristics of project success (time, budget, and customer satisfaction). An online questionnaire was used as a survey tool to obtain data from project managers/PMO/PD and team leaders of various projects in Indonesia. The dataset was subsequently analyzed using SmartPLS-SEM. This paper proposes a conceptual integrated research model of interpersonal skills of a project manager to promote transformational leadership which can positively impact on project success.
