Mockups of data visualisations for Telekom’s family plans.

Overview

Context

I joined an ongoing project: there were already frameworks, basic prototypes, and insights from research.

Team

Composed by researchers, developers, and

designers.

My design team was composed by 4 people.

Objective

Create a new visualization of the contracts & user data.

What did I do?

> Design Research: Worked closely with the research team to iterate and develop a prototype for usability testing.

> User Experience: Designed user flows, dashboards, and interactive prototypes. Created the entire interface, from low-fidelity wireframes to working prototypes.

> User Interface: Applied Design System elements and adjusted the interface according to Telekom’s best practices and style guidelines. Created final resources for the development team.

> Information Design: Determined the most effective graphics for communicating each possible user scenario.

Outcome

Delivered a functional prototype and assets to the development team.

Result

The project was presented during the Mobile World Congress in Barcelona (February 2018)
