Hello
Since the success of a product depends heavily on its usability, the work of a usability engineer is becoming increasingly relevant. A usability engineer is responsible for ensuring that a system is designed to be user-friendly. This refers to the analysis and optimization of already existing systems and applications as well as to the development and support of new systems. A usability engineer oversees the user centered design process across functions. The correct application and implementation of various methods of usability engineering and the design guidelines for user interfaces are the focus here. To ensure this, knowledge in the areas of design, computer science and psychology is necessary. A usability engineer is involved throughout the entire user centered design process. Among other things, the usability engineer is responsible for initializing and moderating the process. This includes the definition of the methods and roles of the employees, as well as the determination of the required resources and the criteria for success control with regard to usability. The work of a usability engineer can have a decisive influence on the success of a product in terms of usability.

Usability describes the extent to which a system, product or service can be used by specific users in a specific context of use in order to achieve defined goals effectively, efficiently and satisfactorily. Usability is particularly relevant in relation to interfaces between humans and technology or humans and machines. In other words, in the development of digital services such as apps and websites Usability focuses on the three factors of effectiveness, efficiency and satisfaction. Effectiveness describes the accuracy and completeness with which users achieve a certain goal. Efficiency is the amount of effort required to achieve the respective goal in relation to accuracy and completeness. Satisfaction is described in terms of usability as freedom from impairments and positive attitudes toward the use of the product.
User experience extends the concept of usability. Here, the user perspective is emphasized and emotional and
aesthetic factors are more strongly included. User experience describes the perception and reaction of a
person resulting from the actual and/or expected use of a product, system or service. User experience is
not only about the mere achievement of a goal, but rather about the experiences that users have before, during and after
using the product.
User experience manages to arouse emotions in users. For this reason, the user experience
is a decisive factor in whether users associate positive feelings such as fun and joy with the product and whether they
would like to use the product again in the future. The success of a digital product is therefore strongly linked to the
implementation of a holistic user experience.
