Constellium
A user-centric, intuitive corporate public-facing website
The client's challenges
Rethinking the end-to-end customer experience
Constellium, a world leader in the development and manufacture of high added-value aluminium products and solutions, decided to redesign its public-facing website. During the project, particular emphasis was placed on the user experience throughout the various development stages, so that user needs were always paramount.

VP Group External Communications and Public Affairs North America
Kaliop was an exceptional partner during the redesign of Constellium’s website, thanks in particular to Cécile’s exemplary project management. The in-depth audit phase was particularly appreciated, as it enabled us to respond precisely to the expectations of our audiences, thus contributing to the project’s success. As a result, we were able to improve the user experience and significantly increase our traffic.
The solution
The objective:
an intuitive, modern and affordable site for the general public
To meet Constellium's requirements, Kaliop implemented a four-stage process: understanding who the users are and what their environment is like; identifying the users' problems and selecting the pain points to be solved; co-designing innovative solutions directly linked to the users' expectations; and then testing the solutions by presenting them to users, in order to challenge our hypotheses.
The process:
user testing at every stage to put the customer at the heart of the strategy
User tests were carried out during each of the four key stages:
- To refine our vision of customer needs and the specifics of the different profiles, a qualitative research phase was carried out via a series of interviews, supplemented by standardised questionnaires also known as "usability scales".
- Once the wireframes had been validated, a phase of moderate testing began, the aim of which was to confirm the initial proposals.
The plus:
A graphic layout that includes the existing identity while adding a modern touch.
After an in-depth study of the existing site, the final phase of the Experience team's work focused on designing a graphic layout based on Constellium's existing identity. The main constraints were to retain the brand colours, simplify the presentation of information, which can sometimes be quite technical, and provide a more modern and accessible image.
