In many companies, procurement is still viewed as an operational activity with no relevance to business success. The processes are complicated, time-consuming, and lack a strategic focus. To address these issues, electronic tools have been developed and implemented in practice to support and automate procurement processes. The use of such tools is referred to as e-procurement. The failure of e-procurement projects in companies is often not due to the concept of e-procurement itself, but rather to a lack of understanding and errors in implementation. This book can serve as a guide for decision-makers, project staff, and students who want to familiarize themselves with the practical aspects of e-procurement and seek support for a corresponding project.
