A Conceptual Framework for Impact of Project Complexity on Success of Railway Construction Projects: The Moderating Role of Effective Communications to All Stakeholders

Abstract

The aim of this study is proposing a framework for the roll of effective communications to all stakeholders in moderating project complexity to improve project success. This paper deeply reviewed the studies published in project complexity and it is effect on success of construction project. This research reveals that effect communications as the most important factor can play a significant role in influencing the relationship between complexity and project success. It was confirmed from previous studies that the negative impact of project complexity on success of construction project is conclusive. Complexity dimensions identified by the Project Management Institute (PMI) into three groups are: human behaviour, ambiguity, and system behaviour. Many empirical studies proved there is a positive and significant relationship between project complexity and project success. Thus, there is a need for a moderating variable to enhance the success of complex construction projects. In this study the main contribution is bridging this gap of knowledge by empirical examining the relations between complexity of construction projects and project success with the interaction of effective communications to all stakeholders as a moderator. This study will enhance development of construction projects in Malaysia and assist scholars and practitioners to achieve maximum project success.
