What is UX-Design

For my first article, it seemed essential to me to explain to you what isUX design, what is the job of UX Designer and in what scope it operates.
ux definition
User experience comes from English”User experience”, abbreviated as UX. It is the emotional feeling of a user in front of an interface, an object or a service.

For a very long time, the sponsor's needs were the only ones taken into account by the agencies when designing the interface. We often heard phrases such as “The customer doesn't like the color of the buttons green, change them to blue”. These often subjective changes could have a direct impact on the experience then lived by the user, then lost. 

UX-Design (User eXperience Design) is a discipline whose the objective is to design a product at the service of users. The difficulty then is to bring together the strategy of the former with the reality of the latter, who today have decision-making power through their uses and behaviors. UX-Design then proposes a real reflection upstream to ultimately guarantee an optimal user experience.

To obtain an optimal experience, a creation process formalized by Jesse james garrett in the Elements of User Experience, ensures the quality of the deliverables. Indeed, this experience is subjective and changes over time and circumstances.
Ce process is summed up in five steps :

  • La strategy : Define user expectations, business objectives and what we are going to talk about.
  • Le perimeter : Delimit the solution so that it is suitable. Discover all the concrete context of the company.
  • La structure : Organize and prioritize information.
  • Le skeleton : Design zonings, wireframes and define the location of each element.
  • La surface : Create the model, add the graphic layer.

Completing these tasks can seem chaotic and naturally entails iterative work before arriving at the most optimal solution. This methodology therefore makes it possible to follow a logical order to satisfy these subjective and changing needs, not responding to simple Cartesian principles.
Nevertheless, theUX designer can be based on rules such as Hick's and Fitts' Laws, Gestalt theory or research methods such as the creation of personas, scenarios, user tests, wireframes, etc.
Finally, to exercise this profession, you must have knowledge in different fields but above all avoid all prejudices and try to put yourself in the shoes of the users.
