THE PROBLEM
Lumen's mission is to make people aware of their carbon footprint and energy habits. The app had to make home power data feel approachable rather than technical.
WHAT HE FOUND
The team led with research: personas, journey maps, information architecture, a site map, prototypes, usability tests, and A/B tests, refined through feedback from client stakeholders and outside users.
WHAT HE BUILT
On the team, Thomas designed the phone app's feature set and onboarding, from the welcome screens to reminders and goals that cut energy waste. The app uses a bold, welcoming palette and plain type. The team presented it with a report on personas, journeys, architecture, branding, and the problem statement.
THE OUTCOME
The team delivered a phone app prototype and a report on personas, user journeys, information architecture, branding, and the problem statement. Thomas designed the app's feature set and onboarding, refined through feedback from client stakeholders and outside users.
