The chief executive officer (CEO) is the only executive at level 1 in the hierarchy of an organization (Carpenter & Wade, 2002). All other executives in the organization are at lower levels. At level 2, we find the most senior executives. Level 3 includes the next tier of executives. In our perspective of promoting the chief information officer (CIO) to be the next CEO, we first have to understand the role of the CEO. Therefore, the first chapter of this book is dedicated to the topic of CEO successions (Zhang & Rajagopalan, 2004).
