The paper provides a comprehensive overview of the Technology Acceptance Model (TAM), tracing its origins, key developments, and future directions. TAM, proposed by Fred Davis in 1985, has become the most widely studied model in the field of Information Systems (IS) for explaining and predicting user acceptance of technology. The model posits that user motivation, influenced by perceived usefulness and perceived ease of use, is a primary driver of system use. Over time, TAM has evolved to include additional variables such as behavioral intention and external factors like system characteristics and user training. Despite its popularity, TAM faces criticism regarding its theoretical assumptions and practical effectiveness. Researchers have noted limitations in the methodology used to test TAM, the variables and relationships within the model, and the core theoretical foundation. Future research is needed to address these issues and develop more robust models for understanding technology acceptance.The paper provides a comprehensive overview of the Technology Acceptance Model (TAM), tracing its origins, key developments, and future directions.
