خلاصه	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 Technology Acceptance Model 2 (TAM2) was developed by Davis and Venkatesh in 2000 and published in Management Science. TAM2 extends the original TAM by incorporating social influence factors and job relevance moderators that explain how users form perceived usefulness beliefs. TAM2 is grounded in longitudinal field studies across multiple organizational contexts and systems.
