BACKGROUND

BACKGROUND

In 2018, Dexcom began the design and development of G7, its next generation of Continuous Glucose Monitoring (CGM) system. The existing product on the market is Dexcom G6.

Problem

Prior to G7, there was no software product design system available at Dexcom.

The existing visual language on the G6 app does not meet the growing needs of Dexcom’s global user base, including accessibility and diverse cultural representation.

Business Goal

Implement a new, comprehensive and scalable visual system across Dexcom’s product portfolio, to replace the visual system of G6.

My Role

Visual Design Lead on the Dexcom Product team of approx. 50 people. In this role, I manage and evolve our in-app illustration and animation output and systems along with UX and UI development for new generations of products.

Business Goals

  • Develop internal visual capabilities

  • Human Factors testing of new visuals prior to FDA submission

  • Iterate and re-test

  • Launch post FDA-approval

Collaboration with BUCK on Dexcom G7

Dexcom worked with BUCK to define and develop a unique visual framework as part of G7’s user interfaces.

Together we developed:

  • Versatile categorization scheme that created space for innovation

  • Accessible color palette

  • Unique style

  • Scalable framework

  • Improved representation and inclusion

Develop Internal Capabilities

After the collaboration wrapped up with BUCK, I focused on developing our internal capabilities to continue developing visual design assets within the framework co-developed with BUCK.

Expand to Animation

We began developing animated in-app videos to educate users about complicated feature sets based on the newly developed illustration style.

Testing Prior to FDA Approval

Given Dexcom G7 is an FDA-Class 2 medical device, many visual assets inside the G7 app are required to meet FDA safety criteria.



Impact

Revolutionized the visual language of Dexcom G7 to improve accessibility and cultural representation, while achieving superior outcomes in user testing. In a nutshell, we humanized diabetes.

The effectiveness for the sensor insertion visual graphics was rated 92 out of 100 based on surveys conducted with the limited launch user group.

As a result, new G7 app addressed feedback from our app store complaints regarding the G6 app’s visuals.

Reflections

It took 5 years to launch the Dexcom G7 globally. I learned how a company of over 6,000 employees rallied together to navigate the complex regulatory landscape and bring this product across the finish line. I’m honored to have played a role in this product, and proud to have pushed the visual boundaries of a medical device app, while improving safety and ease of use.
