UX & UI Design : user satisfaction as a success factor for your projects

How to implement an efficient UX Design methodology?

Why think “user” in a UX&UI design strategy?

More than 2/3 of projects fail due to lack of user approval*. Gathering the business needs and constraints of users as early as possible in the development of a project and consulting them regularly during its implementation, ensures that a tailor-made tool is created and that the experience is pleasant.

Creating a tailor-made tool and offering a pleasant experience for users requires a collection of their needs as well as an in-depth analysis of the business constraints. Including the user throughout the creation process is one of the keys to a successful project.
