This report examines leadership and management principles within the service industry context, focusing on the impact of technology. It begins with an introduction to leadership and management, followed by an overview of classical management theories, organizational culture types (power, role, task, and person), and the roles of leaders and managers. The report analyzes specific management and leadership styles, comparing laissez-faire and autocratic approaches, while also evaluating the merits and demerits of each. It then explores how technology influences leadership and management activities, particularly in the hospitality sector, and concludes by summarizing the key findings. The report uses the case of Wa Pila hotel to illustrate the application of these concepts and provides references for further study.
