Introduction
Up to now, there are many theories of leadership style are
available, like emotional intelligence, contingency, competency
and so on. All of them claim that appropriate leadership style can
benefit project success. This study aims to find the relationship
between leadership style and project success. Three aspects of
literatures were reviewed including leadership style, project
success factors and the match of leadership type and project
type. From the literature review, it was interesting to find that
leadership was rarely considered by the critical success factors
of the project. Turner and Muller (2005) contemplated that
probably the project manager’s neglect themselves or leadership
is not covered in research. However, other reviews show that the
effect of manager is critical to the project. By studying the mold
built by Yang (2011), it is learnt that leadership influence the
project success through teamwork. While some of the fifteen
leadership competencies (Dulewicz and Higgs, 2003) are directly
related to project success factors. So it is concluded that, in a
certain project type, appropriate leadership can improve project
success in two ways, both teamwork and direct impact. A simple
system dynamic model was designed to show the relationships
within project management. However, there were no researches
done to prove this conclusion. Further study is needed.
