CASE STUDY Healthcare
Willow, a Silicon Valley-based healthcare startup, is completely re-imagining the way busy moms pump breast milk with an innovative, patented technology called the Willow Wearable Breast Pump.
To realize its product vision and get it to market as quickly as possible, Willow required a combination of manufacturing innovation and digital technology expertise.
FDA-Approved, Patented Technology
Used by more than 70,000 Women in the US
Ranked one of TIME Magazine’s 25 Best Inventions
In 2019, Willow partnered with Infostretch to deliver on the digital technology aspect. This included the development of a companion mobile application with firmware testing and verification. Infostretch employed a “blitzscaling” approach to deliver the project within six months, developing a complete device firmware protocol test framework. In addition, Infostretch provided end-to-end mobile application design and development, as well as application automation framework design and development.
Developed from scratch, ready-to-use for firmware verification on manufactured devices and FDA compliance verification.
New architecture of the companion app for scalability and performance improvement.
Leveraged an off-the-shelf automation framework to accelerate cycle time by 80%.
Accelerating the delivery of new digital initiatives with confidence
Creating the infrastructure and foundation to scale digital initiatives
Leveraging data and analytics to continuously improve digital delivery processes
The Willow Wearable Breast Pump is a Class C medical device subject to strict FDA compliance requirements. In addition to the physical breast pump designed and manufactured by Willow, each of the software and messaging components also had to be developed with functionality and performance fully verified before and after the breast pumps were manufactured. In some cases, Willow was testing functionality that had never been developed before. There were a variety of difficult technical challenges which needed to be addressed in a timely manner, all within tight FDA compliance requirements.
Infostretch started by conducting a thorough analysis of Willow’s functional and application architecture requirements and developed a proof of concept to confirm all QA automation requirements.
From there, the scope of Infostretch’s engagement included a combination of digital engineering and quality engineering. A ten member multifunctional Infostretch POD worked with Willow in four phases – Discovery, Development & Integration, Verification & Validation, and Implementation & Production Set-up.
The outputs from this effort included:
This included both the application layer and wireless interfaces. Infostretch handled the development of all functionality for both Android and iOS applications, as well as the automation of testing for all application functionality on both operating systems.
The Infostretch team was responsible for developing the BLE protocol test framework, data format, data structure verification format, and all QA and testing for the BLE wireless interface.
This included data logging and algorithm verification for functionality like controlling the rate of milk suction, amount pumped, auto-shutoff when full, etc. in the wearable breast pump.
Infostretch validated all device functionality and performance and verified compliance in a variety of different possible usage conditions.
Infostretch also worked with Willow to customize its cloud presentation layer for data engineering and analytics.
Infostretch collected analytics on usage, device performance, user experience, adoption, and fed it back into Willow’s existing custom and off-the-shelf analytics packages.
By solving the difficult software development, performance and testing challenges, Infostretch helped Willow get its patented innovation to market in a timely manner, fully compliant with FDA requirements, and with full user functionality. It was a win for all involved – and especially busy, multi-tasking moms.
