product design

01 summary


the project brief

Assist the management team with user research and UX/UI Design to create an app based on an existing app.

A blueprint was created by the client's UX researcher and set the stage for the scope of the project. 30 screens where documented in detail describing the functionality & screen content.

From that I scoped the amount of work to turn this into a user-centered design ready for development.

user data

Based on conducted user interviews it was more likely to have an 'only show XL parking spots'* vs. don't show S,M and/or L parking spots.

*for people with big SUVs or where bad at parking

Nur XL Parkplätze anzeigen an oder aus

business requirements

Also from a business perspective it turned out to be a huge overhead to determine S, M & L spots and to communicate this to the user.
