Megaproject Complexity: Conceptual Study from Complexity Theory

Many megaprojects in the world fail. The complexity is considered as one of the causes of megaproject failure. However, the complexity concept in megaproject is still not been clear yet. This study is clarifying and providing an overview of how to overcome the complexity in megaproject context from the complexity theory perspective. The qualitative study approach based on literature exploration succeeds in expanding the complexity theory in organizational and project into the megaproject context. The complexity is a matter related to the relationship of activities, processes, and entities with varying levels of linearity and uncertainty. The megaproject complexity system consists of complicated, complex, chaotic, or even all three conditions occurred. In order to overcome the complexity, the megaproject management need be adjusted under its condition.
