The market for implantable cardiac monitoring devices has rapidly grown, leading to an exponential increase in data. Device nurses face challenges managing this overwhelming data burden, which hinders their ability to provide high quality care to their patients. Current workflows lack efficiency and essential tools for ECG adjudication. Clarifying the importance of data remains a concern, as many device alerts are non-actionable, causing unnecessary work.
The business goal was to focus on the aspect of a device nurse's day to day interaction with our product that would have the most impact. By learning more about their end to end workflows, we can start building a product that best support those workflows, improve tooling, and create a framework that would support future growth and opportunities.
I collaborated closely with leadership to ensure our development process and strategy was driven by UX. The core leadership team comprised of a PM, PO, PDM, technical architect, and UX lead (myself). We defined our business objectives, scope, project plan, development process, and KPIs. The development roadmap aligned to the UX priorities and our key metrics plan ensured that we will be able to measure success.
Our approach was to take the journey with our users every step of the way. Throughout the development lifecycle and after release, we continued to partner closely with our users with consistent monthly engagement to test our assumptions, identify opportunities, and test designs. This helped drive our direction, solutioning, and gave us the ability and confidence to pivot as needed.
We developed a comprehensive solution that emphasizes alert prioritization and guides users through the process of thoroughly reviewing all relevant device data.
Key innovations include: a brand new ECG visualizer with higher fidelity and key tooling to aid in quick and accurate episode adjudication workflows that provide seamless access to patient context and history, allowing users to stay focused on the task at hand without needing to navigate around hunting for information; a guided workflow that facilitates triaging, to review, to documentation and routing.
From static reports to data driven interactive workflows
The Medtronic Design Global System provides a common language and tooling to bring together designers, developers, and researchers, operating independently yet harmoniously toward a shared goal - to create the best possible experience for patients, caregivers, and healthcare professionals.
Medtronic lacks a centralized design organization, with each business unit operating in silos. As I designed and developed the design system for our cardiac space, I looked for ways to bring global coherence to all of our digital products. Through various partnerships with other orgs and the brand team, I eventually organized and led a global committee of UX practitioners across multiple business units to evolve the cardiac platform’s design system I had created, into the official Medtronic Global Design System.
The design system includes Figma component libraries for web and native mobile platforms, development kits, and a documentation portal. The Figma libraries are built with a focus on usability, extensibility, and maintainability. Designs leveraging the component library automatically respond to light and dark modes with a simple toggle. The native mobile components can also switch between iOS and Android. These capabilities allow designers to build a single screen and have those designs translate seamlessly to four different color and platform modes without any additional effort.
Carelink is the centralized platform for Medtronic’s cardiac patient monitoring system. Patient cardiac devices are continuously sending data into Carelink so that nurses are able to remotely monitor their patients and provide the appropriate level of care. The clinician application is crucial in helping nurses triage patient alerts quickly and accurately adjudicate detected cardiac events.
As the user experience lead, I helped to bring a legacy system onto the cloud, leveraging modern architecture, transforming to a brand new UI tech stack, and adopting new and improved design patterns. I continue to be the champion for the voice of the customer, driving our strategy towards enabling our users to perform their daily tasks more easily and accurately.
Netbackup is the leading enterprise data protection solution for fortune 500 companies. While it is the market leader in its field, today's competing products are easier to setup, more visually refined, and requires much less training to use. As the industry moves away from seasoned backup admins towards more generalist users, the user experience of NetBackup needed to be updated to match those trends.
I led and designed a brand new web UI with new protection methodologies, workflows, and role-based access to replace a 20+ year old Java GUI.
As an organization, there is a lot of data hidden away in databases that could be extremely beneficial if exposed in the right way. Engineers and business managers were relying on exporting this data to excel spreadsheets and spending many hours trying to make sense of the data.
The goal was to build a web-based dashboard application that would help the engineering team gain access to this data easily and customize the view of it so they can make business critical decisions and speed up their daily routines. The app allowed users to create custom dashboards filled with widgets displaying data that is pertinent to their jobs. Widgets are fully customizable to properly query the desired data and display it in an easily consumable format.
As the sole engineer assigned to this task, I was the primary product owner, architect, researcher, designer, and developer for this project. I started this project as a forerunner in using AngularJS to develop a single page web application in the org. It was important to develop an architecture for a framework that would be easy to build upon and allow for others to contribute as well. I created a dashboard framework where I can easily enhance capabilities, build out new widgets as needed, and be independent from the backend API layer. The backend capabilites of this application was built around a microservices architecture that allows for proper versioning and containerization of APIs. The framework was designed to allow creation of new widgets within minutes by people with no web development experience and minimal training.
I’m passionate not just in building great experiences, but using design and art as a creative outlet while having some fun and building culture within the org. Here is a sample of various artistic creations I’ve made.
