The current Philips app is not focused on long term preventative care. I proposed a lifelong health data repository that fuels a digital health coach, to help transition healthcare into a system that is proactive about health, rather than reactive about sickness. I presented this project to a team at Philips, and received positive feedback about the project’s long-term aspirations and alignment to many of their goals.





My Roles

  • UX & UI Designer

  • Design Researcher

  • Design Strategist

  • Collaborator


Health data is compiled in many different places through a person’s life, making the entire experience of healthcare fragmented and impersonal. How can the aggregation of health data make the experience of healthcare more holistic? How can this be used for preventative care, instead of our current system of sick care?

My Design Process


Through a collaboration with Philips, I worked with service designers, marketing directors and other innovators at Philips, to come up with modifications to their existing health platform. I proposed a new user experience for aggregating health data throughout a person’s life time, as well as a new app that provides actionable health advice. I presented this proposal to a team at Philips, who provided feedback and useful steps forward.

Define the Problem


The healthcare system needs to focus on long-term preventative care

The 2030 problem is assuring that sufficient healthcare resources are available in 10 years, when the elderly population is double what it is today. “We need to start preventative care today, so we can have healthcare for future generations.”

-Sonal Mattai, Marketing Director at Philips



Secondary Research


Philips has the capabilities and scale to innovate within healthcare

I began with researching Philpis Wellcentive and their existing capabilities. Since they have already built long-term relationships with hospitals and other care providers, this would be useful for achieving the goals of preventative care.

  • Population health management - Philips provide strategies and resources for care providers to manage the health of a large number of people

  • Manage health data - Philips helps hospitals manage, organize, and make sense of their health and medical data

  • Create care plans - the Philips platform enables patients and care providers to factor in the social determinants of health and develop ways to engage patients in their own health



Client Interviews


Preparing for my interviews with Philips collaborators

I prepared questions for my collaborators. For each person I interviewed, I customized my questions based on their role at the company. I also organized my questions into sub-themes, so that the conversation could flow a little bit more naturally.


I interviewed employees at Philips, and some became collaborators.

Their insights focused on value-based and preventative care

While I had a huge collection of notes, quotations, and new ideas, I needed a way to organize these interview notes. I started by categorizing these transcriptions into broad themes or categories. I then stack-ranked them in order of importance. Below are some of the insights I heard after speaking to my Philips collaborators.



Define Opportunity


I used SWOT to synthesize my research about Philips

Below are the key points, within my Philips Wellcentive SWOT analysis, that I wanted to address. These points, gathered from my Philips interviews, press releases, and broad internet research, were the most relevant to the topic of preventative care.


  • Is already doing population health management

  • Has access to pools of patient medical and health data

  • Is moving towards value based health care

  • Is focusing less on hardware and more on software

  • Is integrating personal coaches into their health platform


  • Insurance companies have the power to provide or not provide health care incentives

  • Preventative care requires long term lifestyle changes

  • A unified health database is one of the biggest struggles within the industry

  • Some people still might not feel comfortable storing and sharing their health data


  • Their platform does not aggregate all types of health data

  • They primarily target patients with chronic diseases, which lacks wider impact for preventative care

  • Not looking at a person’s lifelong relationship with their health data


  • I identified the following opportunities



New User Personas


My target audience was new moms, who are able to instill habits in the next generation


Create a lifelong relationship between users and the Philips app

I created a user journey flow for the app throughout a user’s lifetime.





Organizing the idea and thinking about the user experience

I thought about a lifelong user experience of this product and app. This repository of health data is most useful, in the context of preventative care, when it is compiled over a lifetime.

Understanding the user flow with paper prototypes

How someone would engage with a health repository? There needed to be some benefit that this repository could provide. I thought back to what my Philips collaborators were saying about a health coach being important for patient engagement. How could I embed this idea into this app experience?



User Testing


Prototyping the value proposition and getting feedback

Before moving to more high-fidelity wireframes, it was important for me to test if the value proposition of this idea even mattered to people. If the goal of collecting all of a patient’s health data, was to provide holistic health advice, I wanted to find a way to test if people thought this was useful. I did this by asking 5 diverse people of various age ranges, to be my user testers. Throughout the day, I texted them 5 different types of health notifications. Some were really severe, like “you are showing abnormally high blood pressure levels” and some were less severe, like “you haven’t been drinking enough water today.” With this study, I was focused on a higher level understanding of what people care about, regarding their health.


Feedback from User Testing

I categorized the feedback I got. Some of the other insights are shown below.



User Surveys


Surveying people about health data privacy concerns

Another major threat that I identified in the SWOT analysis, was that people may not feel comfortable having all of their health data in one place. This was something I could figure out with a simple survey, so I had 17 people of varying age ranges fill out this survey asking about health data privacy concerns.


Making sense of the survey results

After compiling the results, there was a pattern emerging that could indicate that future generations may be more open to storing and sharing their data. I organized the respondents from youngest to oldest, and found that the younger respondents were more comfortable storing and sharing their data with doctors and insurance companies.



Design Iterations


Getting feedback from design iterations

Since the habit of adding health data might be burdensome for users, it was important to make this step as easy as possible. I worked from the least possible amount of information to the most, trying to prevent information overload for the users.

  • Iteration 1 - allows users to type in the category of health data they want to add

  • Iteration 2 - allows users to categorize data by where it is coming from

  • Iteration 3 - gives users categories of health data to add to

  • Iteration 4 - gives users categories of health data with a brief description



Interactive Prototypes Feedback


User Testing Task 1 - Store health data

I asked users to decide which category they would store a specific type of health data.


User Testing Task 1 - Name health data

I asked users to name their health record and store it.


Task 3 - Search health data

I asked users to search for a specific health record.



Final Solution


Promoting a lifelong relationship with health and medical data

The existing healthcare system is one where our health and medical records are scattered in various data bases throughout our life. My proposal is an app and platform that promotes a life-long relationship with health and medical data. This aggregation of health data is used to power a preventative care health coach.


Data is stored in a physical key. Data is transmitted through the app.

A capsule acts as a repository for user’s health data and as a digital key for user to securely access their health data.


The smartphone and app only transmits health data, but does not store it



Information Architecture


Mapping out how information and features are organized

After doing an initial user flow sketch, I needed to get a more detailed understanding of how information flows through the app and affects the user experience. I fleshed out some of the critical components of what the information architecture would look like.



High Fidelity Wireframes


Creating high fidelity wireframes for the health repository

The health repository section of the app is used to store and retrieve all health-related data including claims data, health and medical data, social and community data, genomic data, self-generated data, and family history data. The user flow of (1) adding claims data and (2) retrieving health records are shown below.


Creating high fidelity wireframes for the health coach

The health repository uses all of the users health data to power the health coach. One differentiating feature, inspired by user feedback, is the ability to adjust the frequency of notifications. Adjusting frequency would simultaneously adjust the type of notifications the user will receive. If monthly or yearly are checked, the type of notifications become more long term and possibly more severe (i.e. blood pressure trending too high over the past few weeks).

Present to the Philips Team


Feedback from the Philips team emphasized data integration

After the project was finished I was given the opportunity by one of my collaborators, Sonal Matai, to present to his team at Philips. Their feedback back was positive, but they primarily spoke about data integration being one of the biggest challenges within the industry. One of the ways they are able to occasionally sidestep this barrier, is through long-term partnerships and contracts with care providers and other major stakeholders. This was great insight into where the future of this idea could go.





Health notifications needs to be more than a number

Users need more than a health status update. For an effective digital health coach, users need actionable insights that they can act upon.

Health data integration is the biggest challenge within the industry

Care providers are not wiling to give up valuable health data about their patients. This would become a challenge for future stages of this service, which would integrate data from other external sources like insurance companies, etc.

Next steps are to figure out where all health data comes from

The feedback from Philips provided great insight into how they attain their health data: through partnerships. The next steps for the development of this idea would be to study the competitive landscape more and figure out how to leverage partnerships as a key strategy for making this life-long health repository work.
