Corporate governance is a key factor in any successful company. The model of governance adopted by an organization shapes its management, policies, systems, structures, and overall strategic framework. The different models of governance offer unique approaches to leadership and decision-making. To create an effective governance "operating" model, it is essential to understand the fundamental principles of the four key models of board governance. These models include the Independent Director, the CEO with Non-executive Chair, the Dual Mandate, and the Non-CEO Chair.
