Led and Redesigned a Desktop Configuration Tool for Hospital Monitor Devices By Increasing Technicians' Task Success Rate and Reducing Operation Time
About
Sketch is a desktop configuration tool that enables Masimo technicians to set up Masimo hospital monitoring devices by configuring Early Warning Score (EWS), Vital Signs Check, and EMR integrations to meet each hospital’s requirements.
The Challenges
Within a year of the initial Sketch launch, the company requested a redesign after majority of the technicians reported operational issues that reduced performance and hospital handoff efficiency.
The Pain Points
High Learning Curve
Inconsistent Inaccessibility UI
Long Operation Time
Unclear Guidance
The Current System
The Goal
Sketch redesign aims to enhance the overall user experience by reducing the learning curve and boosting user’s work efficiency. Its goal is to increase task success rates and shorten operation times, enabling faster hospital delivery with configured devices, thereby strengthening client relationships and trust in Masimo.
The Opportunities
Clear Guided Experience
Reduce
Operation Time
Ease to Use
Consistent Accessible UI
The Vision Ecosystem
My Role
As design lead, I drove the Sketch UI rebrand and established the first design system while simplifying configuration steps, increasing task success rates, reducing operation time, and improving overall user satisfaction.
My Contributions and Achievements
Impacts
The product was launched internally in May 2025, after I left the company, so the impacts success metrics are primarily demonstrated by the highly positive results from our usability testing.
Final Deliverables Highlights
01 Policy Source
How can we provide step-by-step guidance to teach users device setup and import methods for each device in Sketch?
Before • Unclear Guidance
"I can't remember each device's import method; Sketch has no step‑by‑step setup guidance, causing longer operations and more errors."
After • Clear Guided Experience
“This is a game changer. The step‑by‑step tutorial is helpful, saves me a lot of time, and helps me avoid missing steps or making mistakes during setup.”
02 Create Custom Parameter
"How can we create a visual hierarchy, scalability, and mental model that allows users to focus on their tasks using familiar UI components and behaviors, without the need to learn new patterns?"
Before • Inconsistent Inaccessibility UI
“Creating a custom parameter is difficult; no instructions and inconsistent component behavior slow my workflow.”
After • Consistent UI
“The new design makes creating custom parameters clearer and easier with improved navigation, cleaner layout, and consistent UI behaviors.”
"How can we offer a more intuitive experience with less learning curve and higher complete task rate with less operation time?"
03 Add Contributing Parameter with EWS
Before • Long Operation Time + High Learning Curve
“Adding contributors is difficult, no instructions, inconsistent UI, and no back button force me to redo edits after mistakes.”
After • Reduce Operation Time + Low Learning Curve
“This would make setup a lot easier with clear instructions, a progress bar, consistent controls, and Back and Edit buttons so I can undo my mistakes without starting over.”
