During the summer of 2022, Tandem debuted a much-anticipated feature for the t:slim X2 insulin pump and the t:connect mobile app — the freedom to bolus directly from a smartphone!* For years, our users have asked for a more discreet way to bolus. Now, t:slim X2 pump users can manage their diabetes in a whole new way.
"It was the number one request we received from existing customers and people exploring whether they were going to use the t:slim X2," Suzanne McKee, Senior Product Manager, said. "It's been incredibly exciting to answer that call and give the next feature and functionality users really want."
Get a behind-the-scenes look at three individuals who worked as part of an extended team to bring this latest milestone to life.
Meet Suzanne Mckee, Senior Product Manager
Suzanne loves working at a company that listens to its users and understands where to put priorities and efforts in innovation. As an innovative end-to-end system, this latest development relies on communication between the t:slim X2 insulin pump, the t:connect mobile app, and the cloud in order for a user to bolus from their smartphone.
"Everything needs to work together," Suzanne said. "This is the beginning of getting more sophisticated with app control and mobile control of pump software. The t:slim X2 insulin pump can also be updated remotely, so users don't have to wait until the next round of warranty to get features and benefits. They can stay up-to-date with every innovation."
As a mother to a 13-year-old daughter who lives with type 1 diabetes, Suzanne has a firsthand understanding of the freedom being able to bolus from a smartphone offers. Her daughter gets to choose what's most convenient in the moment. During the night, Suzanne and her husband can step in and help with the app, if needed, using the phone on their daughter's bedside table while she continues to sleep — no more rustling through the bedding to find her pump.
"For us as a family, I want to do anything I can do to take some of the burden away from my daughter," Suzanne added. "There's flexibility in not just starting a bolus, but also in being able to stop a bolus. Our daughter self-manages, and my husband and I are there to support."
Meet Nancy Terjung, Associate Director Of Human Factors Research
The Human Factor Research department at Tandem plays a vital role in launching a new product or feature.
"We take an early product through its paces to collect user feedback from the real target user," Nancy said. "And then we incorporate that feedback into the design to have it make more sense or work better — all with a focus on safety. Working in Human Factors, you couldn't ask for a better company that supports your role."
“Everyone’s really passionate about doing the right thing each and every time to deliver the best products for our users.”
To test, improve, and iterate the mobile app feature for FDA approval, Tandem conducted the largest summative study ever run within the company. For Nancy, the most exciting part of this Herculean feat was being able to give users something they both wanted and needed.
"All we heard was, 'I cannot wait to use this!'" Nancy said. "Prior to this new feature, we had the mobile app, which was great to know what was going on, but now users can interact with their diabetes management and have an impact on it in a more private manner."
Meet Bernice Tuazon, Senior Software Tester
With a focus on thoroughly testing all aspects of the t:connect mobile app prior to releasing a new feature into production, Bernice Tuazon understood that her role required a unique mentality. She put herself in the mindset of a pump user to best understand what features they would be using on a regular basis for the most seamless experience possible.
"I attended some summative studies," Bernice said, "And was like, 'wow,' watching the connection between the app and someone using this in their day-to-day life."
Bernice appreciates hearing feedback about the new feature coming in through customer surveys, emails from company leadership, and of course, seeing comments on social media. She likes hearing how much people enjoy the convenience, flexibility, and discreetness of being able to bolus directly from a smartphone.
All three Tandem team members are enthusiastic to continue working across different departments to develop more forward-thinking developments in type 1 diabetes management.
