MedTech Design Sprint

User research and UI design in two days.

Ever thought of picking up the habit of reading? Or start jogging to get in better shape? Or regain calm of mind by meditating? These things are what goal setting can do to help people build habits. Goal setting is no longer limited to just fitness achievements, but other beneficial habits to learn more efficiently, be more productive, or just be an even better person.


This project is the result of a self-imposed design sprint for two days as part of a job application for a MedTech startup. I had to develop 2-3 mobile interfaces that helps people set goals and track them.


User Research

I began with user research on goal setting. According to clinical journals and user interviews, goal setting is used to induce behavioural change for positive habits, especially for patients with chronic conditions, to maintain their way of life or even improve it. Goals are setting according to the SMART framework, to make them achievable and realistic. However, goal setting is not limited to just health-related targets, it can be applied universally, one of the interviewees tried to set goals to pick up the habit of reading one book every month.


User Flow

I mapped out the flow for people wanting to set goals, whether that is through an app, or other tools, to assist me focus on what screens to design. It became apparent that I should design interfaces that can be visually enticing yet functional, so I decided to design the goal setting interface, dashboard showing an overview of ongoing goals and progress breakdown interfaces.

Sketches and Wireframes

The goal setting was essentially in a sign up sheet format, where people can type in whatever goal they would like to set, and set the difficulty and duration. I thought the dashboard should be as simple as possible, showing each goal in a queue card manner, with a circular progress chart. People tap on the goal, which takes them to the breakdown of progress. The page shows them each day’s progress, if they’ve exceeded their daily goal or not. This is where people can log in their goals if they haven’t.


User Testing + Further wireframing

Next, I conducted an usability test with my wireframes. The key takeaway was from the following quote,

“for many people they wouldn’t know how to start, so some suggestions will be helpful.”


It appears my goal setting interface is not helpful enough for people who are just getting started. With that in mind I redesigned screens that gives goal suggestions for people to start, and added motivational messages to further encourage people to try. Similar motivational messages are also included in the difficulty setting interface, where users are able to set goal parameters, for example the length of each interval, and total time period of the goal.


Final Deliverable

I envisioned the app to be encouraging people, and without being overloaded with visuals. By this point I only had around half a day left in the design sprint, so I needed to be quick. I thought using gentler colour gradients, will produce a friendlier aesthetic, making it more encouraging to interact with. Each gradient will be used to categorise goals, which is used in all interfaces. I designed two extra screens that categorises different goals that people can try, and a progress interface for ongoing goals.
