PhD Defence Folkert Mulder


In his dissertation, New Forms of Leadership, ERIM’s Folkert Mulder explored how global developments had dramatically altered the business environment, creating a need for innovative leadership approaches. Folkert argued that traditional hierarchical leadership structures were no longer sufficient to address the complexities of modern organizations, which faced evolving demands, innovative business models, intricate supply chains, and rapid digitalization. Through his research, he highlighted the importance of moving beyond singular leadership models, thus advocating for a pluralistic approach where multiple leaders collectively navigate challenges, ensuring efficiency, transparency, and resilience. This shift towards a more distributed leadership structure enables organizations to better manage the dynamic and interconnected landscape, ultimately enhancing their ability to adapt and thrive in a rapidly changing world. 

Folkert defended his dissertation in the Senate Hall at Erasmus University Rotterdam (EUR) on Friday, 1 March at 13:00. His supervisors were Prof. dr. Steffen Giessner (EUR) and Dr. Bas Koene (EUR). Other members of the Doctoral Committee were Dr. Bex Hewett (EUR), Prof. dr. Daan Stam (EUR), and Prof. dr. Marc Salomon (UVA).

Thesis Abstract

The increasing complexity of society and the business environment results from numerous interconnected global developments that have shaped the landscape in which organizations operate, such as evolving demands, innovative business models, intricate supply chains, and the rapid pace of digitalization. With that, leaders encounter new challenges questioning the so-far advocated leadership styles and skills, which is crucial in navigating and harnessing the potential of the complex and dynamic business landscape described.

In the face of changing market dynamics and disruptive new business models, effective leaders must embrace innovation, oversee, and optimize complex networks, ensure efficiency, transparency, and resilience, and collaborate with multiple stakeholders across geographical locations, and foster effective communication and coordination. More and more organizational trends are moving away from this traditional model of organizing towards, new forms of organizing across organizational boundaries, The needed leadership style often demands a different leadership setup and often more leaders involved to manage the complexity. Traditionally, leadership has been framed within a hierarchical structure, with a single leader at the top guiding their followers.

All of these changes lead to new ways of thinking about leadership, whereby we may need more than one leader to tackle the current problems, which has been referred to as leadership in the plural.
