1. User Acceptance of Information Technology UTAUT (Vankatesh)
By Laraib Nasir and Saima Masud

2. Origin
It is a technology acceptance model formulated by Venkatesh and others in "User acceptance of information technology: Toward a unified view".

3. Elements/ features of UTAUT
The UTAUT aims to explain user intentions to use an information system and subsequent usage behavior.
The theory holds that there are four key constructs:
1) performance expectancy
2) effort expectancy
3) social influence
4) facilitating conditions
Gender, age, experience, and voluntariness of use have an impact on the four key constructs on usage intention and behavior.

5. Criticism
Bagozzi critiqued the model and its subsequent extensions, stating “UTAUT is a well-meaning and thoughtful presentation,” but that it presents a model with 41 independent variables for predicting intentions and at least 8 independent variables for predicting behavior,” and that it contributed to the study of technology adoption “reaching a stage of chaos.”

7. Element/focus: Focus on the rational employee interest
Feature: User acceptance models explain user intentions to use information technology.
They represent a mature research area in academic technology research with a focus on information technology (IT).
