I was commissioned to help redesign an application geared toward technicians for RATP-ACEA, a French group specialized in maintaining and monitoring elevators and escalators across the national railway network.

Defining the problem
The goal was to help technicians report broken engines when on a mission. I worked on the UI/UX Design by defining pain points, the previous app was lacking in readability and the user flow needed improvement. We tried to learn as much as possible what is important to the users by completing heuristic evaluations, reading feedback reviews and analyzing similar apps geared toward professionals. Here is what users should be able to do :
1. Report damages and issues ;
2. Export and import reports from the database;
3. Check the planning for future interventions.
Sketching & paper testing
We drew rough sketches of what we imagined the interface would be. These detailed the overview of tasks as well as the interface. The sketches helped us brainstorm how we could change the interface after receiving continuous feedback.
Wireframing & interfaces
Thanks to the feedback from users I was able to create a cleaner interface than the original. With a persistent type tab bar, we were able to fit more items of the same importance. The navigation hub lists all the navigation options and is known to work well in task-based websites and apps, especially when users tend to limit themselves to using only one or two branches of the navigation hierarchy during a single session.
Prototype
The key was to pick a navigation system where the inevitable downsides would hurt users the least for tasks they perform frequently: writing and accessing past reports. With the use of colored boxes to signify the urgency of the intervention, to give consistent visual feedback that will persist throughout the whole experience.
