Simplifying how adults with Type 2 Diabetes understand their data.
KEY GOAL
Deliver a mobile app (iOS/Android) that educates adults with Type 2 Diabetes to improve their daily diabetes management.
RESPONSIBILITIES
Product Designer. I worked on graphs and information architecture using Glooko core app as our base. I worked cross-functionally with UX, PM, UXR, ENG, QA, and Legal.
CLIENT
Novo Nordisk is a global pharmaceutical company that develops treatments for people with Type 1 and Type 2 diabetes.
SUCESS
Users sync their devices 2x as often using the app.
iOS mobile app has 4.6 stars.
TIMELINE
1-month with beta testing.
PLATFORMS
iOS/Android
Design Process
Process took 1-month from brainstorming workshop to first release
Problem
Adults with Type 2 Diabetes have difficulty receiving information that will help explain how their medication, meals, and activity impacts their blood glucose levels.
I assisted our UX Director in a company wide brainstorming session to help our team align on a target user named Robert and understand his needs.
I proposed we update our information architecture, after evaluating our existing app, to help Robert find answers to his questions faster so he can better manage his diabetes.
Usability Testing
Given this was an existing product, I quickly designed a mid-fidelity prototype for concept testing.
In usability testing, I learned participants valued Comparison Graphs the most as it shows how lifestyle events affect their blood glucose levels.
DESIGN DECISIONS
Comparison Graph: Participants were frustrated they could only compare one lifestyle event type to their Blood Glucose at a time.
By Time of Day Graph: Participants did not fully understand how to read the By Time of Day Graph, resulting in not seeing valuable BG patterns.
Beta Testing
For beta testing, I updated our comparison graph so participants can compare all their lifestyle events to their blood glucose at once. Participants said this graph was easier to interpret than the last version.
I worked with engineering to create a beta app to test if participants could easily interpret their own diabetes data.
DESIGN DECISIONS
Tool tip added to help the discovery of the graph interaction.
Expandable graphs so users can still see all event types at once when closed.
Engineering constraints no additional interactions or new graph types.
To help users understand how to read their BG By Time of Day Graph, I designed an animated informational card that participants said was easier to interpret than the last version.
DESIGN DECISIONS
GIF of blood glucose readings from each day stacked onto each other to show users how to read their graph.
Informational card to help users understand their graph.
Outcomes
For our first release, I decided to change the animated informational guide to be a pop-up so it would not be confused with real user data.
“Seeing this information is sobering, it makes me more aware of what I’m doing and how to manage my diabetes.”
While solving Robert’s need to understand his data, I learned how to work fast, stay within engineering constraints, and analyze data to make better design decisions.
IF I HAD MORE TIME
If we had more Engineering bandwidth, I would of liked to explore the Comparison Graph further.
I would ask to conduct research on the nomenclature, after seeing participants use different terminology in testing.
SUCESS
Novo considered the project a success. Novo solidified its partnership with Glooko, generating significant revenue.
SYNC 2X
An evaluation by HITLAB, an independent user research consultant, showed users checked their blood glucose twice as often as a result of using the app.
ADOPTION
Research showed the new Novo app design was preferred over the original Glooko app, so Glooko adopted the new design.
4.6 STARS
The Novo iOS mobile app currently has a rating of 4.6 stars.
AWARDS
Our team was awarded the PM360 2018 Innovative Service award.
TOP 50
Glooko was chosen as one of the top 50 most innovative companies in the World by Fast Company in 2018.
