Study process and deliverables

Our UX Research Consultant Team accompanied Bouygues Telecom Entreprises during 3 strategic moments of their redesign.

Card sorting workshop

We organized a card sort workshop in the form of a focus group with the core target of the site to define the new tree structure. This workshop aimed at understanding the needs of the target and to arbitrate the different card sorting made internally by the customer with the project and business teams.

Card sorting deliverables

Following our analysis of the first study and our recommendations, we delivered two versions of the site tree structure. One with double entries and the other without. We were also able to highlight the expectations of the core target to prepare the work of the user paths.

Wireframe testing in User interviews

Once the tree structure work was completed, Bouygues Telecom Entreprises teams produced low definition wireframes. We submitted those to 15 people from the core target to validate the user paths. User interviews at this stage allowed us to overcome low fidelity wireframes' limits, thanks to live moderation.

User interviews deliverables

The second study enabled us to highlight the positive and negative points of the new paths. Thanks to this, we recommended a dozen or so tailor-made optimisations based on four main ergonomic concepts : Usefulness, usability, accessibility and desirability.

High-definition prototype testing with remote users

Once the paths were adjusted and validated, we set up a remote user test on a high-definition interactive prototype of the new site. This allowed us to understand the design's impact on the user experience.

Remote user test deliverables

By analyzing the feedback and verbatims of the last study, we validated both the modifications of the user paths and the presentation of the offers.
