The book presents the efforts of the NBU team to put forward an integralmethodology for evaluation of E-Learning systems. It has been created within the WELKOM project (2004-2006), financed by the Leonardo da Vinci EC program. The methodology given here has been applied successfully for deploying and optimizing three different E-Learning systems in three different contexts – a private industrial company (Turbomeca, France), a SAP training company (VBS, Bulgaria), and a university (NBU, Bulgaria)
