Résumé	The Unified Theory of Acceptance and Use of Technology (UTAUT) was developed by Venkatesh, Morris, Davis, and Davis in 2003 and published in MIS Quarterly. UTAUT integrates insights from eight prior technology acceptance theories into a unified framework, identifying four core constructs—Performance Expectancy, Effort Expectancy, Social Influence, and Facilitating Conditions—that together predict behavioral intention to use and actual technology adoption.	The DeLone and McLean (D&M) Information Systems Success Model, introduced in 1992 and refined in 2003, provides a comprehensive framework for evaluating information system effectiveness across six dimensions: system quality, information quality, service quality, use, user satisfaction, and net benefits. Unlike acceptance models that focus on adoption intention, the D&M model measures actual realized benefits and organizational impact.
