One of the main design challenges we solved during my time at Carjump was creating one sign-up process for multiple carsharing providers. This meant that we needed to collect data necessary for the sign-up flows of multiple providers in order to allow users to register for them all by completing just one form. I worked closely with a Junior Designer, Product Manager, Android and iOS developers, and the CEO, in order to release an MVP.

User flow
To kick off the design process, I plotted out all of the necessary information we needed to collect through our registration process. Then, I defined all user decision points, and organized the information into a user flow to guide our designs.

Wireframes
Our design goal was to present this hefty registration process to users without overwhelming them. To find the right direction, we created multiple sets of wireframes to represent the different ways the flow could look and feel, and we tested them internally.


Copy
Based on best practices, we split up the data entry to only one or two items per screen in order not to overwhelm the user with a long list of empty fields. We focused on the copy to make the process smoother by creating conversational UI with friendly and transparent copy.
Visual language
Since this flow was a completely new feature, we wanted to define a playful visual language to further aid in making the sign up process enjoyable. The illustration work was done by UI designer, while I was responsible for the interactions.

Screen flows
During the design process, Carjump's leadership kept presenting us with privacy and legal requirements which we had to fit in to the screens. As a result we had to keep adjusting the screenflow while keeping a tight grip on how to be legally safe with the information we ask users for, as well as making sure we don't infringe on their privacy.

Android prototype
The final decision was to develop a functional prototype for Android. What you see are the results of great UX work, heavy edits by leadership, and a lot of privacy and legal constraints which were presented to us after the designs were complete. This prototype was used as a showcase to Carjump investors. Although it was was not the version the product team pushed for, I am proud of the numerous iterations we completed in record time in which we fought for our users through and through.
