My scrum team was appointed for Three mobile account check-out process redesign.
The brief required to refresh the old check-out process along new visual identity while the user journey would has been slight changed: adding the possibility for the user to save his details and come back later via email sending component. After the purchase, the user will receive a customized confirmation email.
Once received the wireframe from UX designer, as UI designer of the team, I started to build up the drafts, component by component, using atomic library and keep in mind the Three mobile website visual identity. After several A/B tests and following weekly agile reviews, we finalised the layouts.
As outcome, there was a significant increase of purchase by clients.
