Habefast Glossary Ux Design


UX design (User Experience Design) is an essential discipline in the development of digital products and services. Indeed, a good user experience is a key success factor for companies that want to differentiate themselves from their competitors and build customer loyalty. In this glossary article, we will explain in more detail what UX design is, its principles and methods, and its importance for the success of a digital project.


UX stands for “User Experience”. The term UX is often used to refer to the discipline of UX Design, which is the design of user-centred digital products or services to enhance the user experience. UX Design considers all aspects of the user experience, including user interface interaction, navigation, content, workflow, visual design, performance, accessibility and usability. The goal of UX Design is to create products and services that meet the needs of users while providing a consistent and enjoyable experience.

The importance of UX Design for the success of your digital project

  • Improve user satisfaction
    UX design optimises the user experience by taking into account the needs and expectations of users. By providing a pleasant, intuitive and efficient experience, you increase user satisfaction, which translates into increased loyalty and reduced abandonment rates. If users have a negative experience with your site or application, they are more likely to give up quickly and look for an alternative with your competitors.


  • Reduce development costs
    UX design identifies problems at the earliest stages of design and development, avoiding the additional costs of making changes later. By anticipating user needs, you avoid design errors and negative feedback that can be costly to correct. As you can see, a well-designed product also reduces training and support costs for users.


  • Improve the visibility and awareness of your company
    This discipline allows you to create products and services that stand out from the competition by offering a unique and memorable user experience. A positive user experience can result in positive reviews, recommendations and word-of-mouth. This can help you attract new users and build awareness of your business.


  • Optimize conversion and sales
    It optimizes conversion rates by making the buying and conversion processes simpler and more intuitive. By reducing the barriers to buying or using a product or service, you increase the chances of conversion and sales. Indeed, a positive user experience can also lead to repeat purchases and increased loyalty.


In conclusion, UX design is an essential discipline for designing digital products and services that meet the needs of users. By providing a pleasant and effective user experience, you increase user satisfaction, reduce development costs, improve visibility and awareness of your business, and optimise conversion and sales rates. For these reasons, UX design is an essential investment for the success of your digital project.

What are the 3 disciplines that converge in UX design?

UX Design is a discipline that involves the convergence of several different disciplines. The three disciplines that are often considered to be the most important are:

  1. Cognitive psychology: studies the way humans perceive, understand, process and retain information. UX designers need to understand the limits of human memory and attention in order to create digital products that are easy to use and understand.
  2. Interaction design: focuses on creating interaction patterns that allow users to interact with digital products in an intuitive and efficient way. UX designers must be able to create navigation patterns, user flows and interaction processes that meet the needs of users.
  3. User research: this discipline involves the collection and analysis of data about users, their behaviours and needs. UX design professionals must be able to conduct user surveys, analyse the data collected and make design decisions based on the results of these surveys.

The differences between UX and UI design

UX design and UI design are two complementary disciplines that are often confused. Although they have similar objectives, they have different roles and responsibilities in the design process of a digital product.

UX design (User Experience design) focuses on the overall user experience with a digital product or service, from the first contact with the product to the completion of a specific task. The UX designer strives to understand the needs, goals and motivations of users in order to create products that are easy to use, intuitive, enjoyable and effective for them. The UX designer’s work includes conducting user research, creating personas and user journeys, designing functional models, conducting usability tests, etc.

UI Design (User Interface Design) is a discipline that focuses on the visual and interactive design of a user interface. This includes the design of buttons, forms, drop-down menus, graphics and anything else related to the visual presentation of the user interface. The goal of UI Design is to make the user interface aesthetically pleasing and attractive while allowing users to interact with it in an intuitive manner.

In other words, UI Design focuses on how the user interface is presented visually and interactively, while UX Design focuses on how users interact with the user interface and how this affects their overall experience.

The UX Designer's tasks

UX Designers work on the following tasks to create an optimal user experience:
  • Understanding user needs: UX designers need to understand user needs, goals, preferences and constraints to create positive user experiences.
  • Designing user journeys: they design user journeys to guide users through an application or website in an intuitive and logical way.
  • Prototype and test: they create prototypes of user interfaces and conduct tests with users to evaluate usability, effectiveness and user satisfaction.
  • Work closely with development teams: UX Designers work closely with development teams to ensure that the final product meets the user’s needs while being technically feasible.
  • Continuously improve: They also monitor the use of products and services to identify opportunities for improvement and development.
