Leadership in organizations appears to be an important mechanism that can manage the challenges of the information age. Leadership models based on the classical management approach are mostly static models based on today's invalid solutions to yesterday's problems and are not flexible enough to offer alternative solutions to organizational problems in a chaotic environment. Complexity leadership refers to an interactive process that involves creating a managerial synergy shared by many complex forces in management, instantly resonating with the competitive, uncertain conditions required by the new era, and flexible, effective decision-making rather than focusing on the organizational member(s). Complexity leadership emphasizes flexible, interactive, dynamic hierarchical structuring that can resonate with new conditions across all organizational hierarchy levels. Complexity leadership is strengthened in complex adaptive systems. It is the intersection of leadership theory and complexity theory. In this study, complex leadership theory and the literature review on it are presented to the reader.
