In the modern global business environment, e-commerce shakes the foundation of most industries, leads to entirely new kinds of businesses, and directly affects both our careers and the way we live. One of the most significant changes is in the manner companies conduct business, especially in how they manage their resources, connect and communicate with customers, negotiate and outsource from suppliers. The main goal of this book is to explain in a systematic way managerial aspects of e-commerce, and demonstrate its value-added capabilities. This book offers a detailed description and analysis of e-commerce business models including their components, classification, and performance results.
