Using a smartphone or web app is an integral part of our automated daily practices, and in order to better understand why technology creates a good relationship with humans we will have to understand the meaning of user experience(UX). The term of UX that appear in early nineties, which is studies the relationships between human and technology. The concept of UX is based on the study and understanding of the user, and through the stages of UX design, it is possible to obtain high-quality products that delight the customer and achieve their goals. In this project we will use UX to evaluate and analyze The Administrative Communications System (ACS)(Enjaz)of Qassim University, which controls internal and external, incoming and outcoming electronic transactions, monitors them,and archives them electronically. In our pa- per, we discussed the concept of UX and its elements, as well as measurements and methods for measuring them. To assess the UX of the Enjaz system, a questionnaire and interviews was chosen. After studying and analyzing the system and identifying the points that cause problems for users, a model will be created that includes solutions to those problems.
