Key Responsibilities

Led project planning, defined the product roadmap, and managed timelines,

taking on key product management duties to ensure efficient milestone

achievement.

Directed the end-to-end design process, from foundational user research

and strategy to final UI implementation.

Established and maintained a scalable design system in Figma that

enhanced product consistency and accelerated development cycles.

Facilitated alignment between design, engineering, and key stakeholders to

ensure a shared product vision and streamlined execution.

The Problem

The hospital's existing system was inefficient and

paper-based, causing daily friction and stress for both

patients and clinicians, and posing risks to patient

safety.

Our Design Hypothesis

We hypothesized that by designing a single,

integrated platform combining daily operational tools

with advanced, real-time IoT patient monitoring, we

could empower clinical staff with a unified, proactive

workflow โ€” simultaneously enhancing efficiency

while elevating the standard of patient safety and

care.

Research Findings

Key Insights & Design Opportunities

Key Finding (The Pain Point)

Design Opportunity (The "So What?")

1. Fragmented & Inefficient Documentation

The heavy reliance on paper documentation made task handovers and

collaboration extremely slow and prone to error.

To build a streamlined digital Task Management Tool that simplifies and

automates high-frequency tasks, ensuring accountability and optimizing care

coordination.

2. High-Risk Manual Room Checks

Manually logging room checks was not only time-consuming but also posed a

high risk of inaccuracies and missed critical duties.

To develop a Revolutionary Health Monitoring Solution that provides non-

invasive, around-the-clock monitoring and visualizes health trends for

proactive care.

3. Lack of Continuous Vital Monitoring

Vital signs were logged on paper, making it impossible to provide the

continuous, 24/7 surveillance needed for high-risk patients.

To create a comprehensive Bed Board Manager and leadership dashboard that

offers a real-time overview of bed availability, patient assignments, and staff

allocation.

4. Inaccessible Operational Insights

Hospital management lacked a real-time, comprehensive view of operations,

relying on slow, manual check-ins with individual staff.

To design a Centralized Key Operation Hub with seamless EHR Integration,

creating a "Single Source of Truth" that eliminates paper and saves significant

time.

5. Increased Risk During Night Shifts

Staff reported that efficiency dropped significantly at night, increasing the risk

of patient emergencies and slowing response times.

To leverage Radar Integration for a discreet active monitoring system that

provides Real-Time Alerts, enabling swift intervention and improving patient

safety during off-peak hours.

Defining Users & Key Workflows

Our research revealed two primary user groups with distinct needs and permissions:

Admin Users and General Employees.

To ensure the platform was both powerful and secure, I began by mapping out their key

workflows, particularly for high-frequency tasks like 'Task Management'. This process

was crucial for defining the role-based access controls and ensuring the user

experience was tailored to each group's specific responsibilities, all while maintaining

HIPAA compliance for patient data.

With the core user flows defined, the next challenge was to structure the entire

platform into a coherent and scalable system. I developed a comprehensive

Information Architecture diagram to map out all key sections of the admin dashboard.

This blueprint served as the biggest source of truth for the entire team, ensuring a

logical foundation for the interactive dashboard and facilitating quick access to critical

data.

The Command Center: Our

Collaborative Hub

"Throughout the project's one-year lifecycle, a central digital whiteboard in Miro served

as our team's 'virtual command center.' This space housed everything from our initial

research synthesis and brainstorming sessions to the system's function tree and multi-

phase planning."

It was an essential tool for maintaining clarity and alignment across the team,

especially given the project's complexity. This single source of truth was vital to

our collaborative and iterative process.

Challenge & Solution

The Challenge of Remote Collaboration

Challenge:

Our team was fully remote, while the hospital we were designing for was in a

different state. This created significant challenges for immersive research

and seamless communication.

My Solution:

I established a hybrid communication model to maximize clarity and empathy. This involved structuring our process around regular remote workshops (using Miro and FigJam for interactive sessions) and planned, intensive on-site visits during critical research and testing phases.

The Challenge of Ambiguous User Requirements

Challenge:

Clinical staff, while experts in their field, often found it difficult to articulate

their specific software needs and abstract requirements.

My Solution:

My Solution:

To bridge this communication gap, I implemented two key facilitation techniques:

  • Internal Role-Playing Workshops: My team and I would role-play user scenarios to transform vague requests into concrete, testable user stories, which we then validated with the users.
  • Visual Mood Boards: I created and shared mood boards with users to provide them with a concrete visual language to better describe their aesthetic preferences and desired "look and feel."

The Challenge of Design-Developer Alignment

Challenge:

In the early stages, discrepancies between our design proposals and the

development team's technical constraints led to rework and delays.

My Solution:

I tackled this proactively with a two-pronged approach:

I initiated and led the creation of a comprehensive Design System in Figma, which became the single source of truth for all UI components and patterns.

I modified our workflow to include mandatory technical feasibility checkpoints with the engineering lead immediately after the user flow stage, ensuring our designs were practical and buildable before moving to high-fidelity UI.

The Challenge of a Dynamic Project Environment

Challenge:

A tight one-year timeline, remote communication, and a busy client made a

traditional "waterfall" process unworkable.

My Solution:

Recognizing this, I championed and helped facilitate the team's transition to an Agile development methodology. This allowed us to deliver value incrementally through MVPs (Minimum Viable Products), gather client feedback in smaller, manageable loops, and iterate effectively. This shift was critical to navigating uncertainty and successfully delivering the entire system.

Final Outcome

The final solution is a modern, unified platform that directly addresses the core problems of

operational inefficiency and fragmented communication โ€” providing a centralized, intuitive interface

that significantly reduces administrative friction and enhances patient care quality.

01

Showcase 1: The Centralized Command Center

The main dashboard serves as the staff's 'single source of truth'.

My key design decision was a modular, card-based layout that

presents complex, high-volume information in digestible chunks.

The information hierarchy surfaces the most critical tasks and

alerts first, allowing staff to assess the hospital's status at a glance.

Showcase 2: Real-Time Proactive Monitoring

The radar monitoring page translates complex, continuous IoT

data into an instantly understandable interface. Color-coded

alerts and clear status indicators ensure staff can identify and

respond to critical incidents in seconds โ€” shifting from a reactive

to a proactive model of care.

The VHS Design System

To ensure consistency and scalability, I established a comprehensive design system including a well-

defined color palette, typographic scale, and custom icon set โ€” becoming the single source of truth for

both design and development.

Project Impact & Results

This project successfully transitioned from a design concept into a fully implemented solution,

delivering significant value to the client.

Successful Launch & Deployment

The VHS platform is now live at the client hospital. The core infrastructure, including the advanced radar monitoring

equipment, has been fully deployed on-site โ€” marking a major milestone in the hospital's technological modernization.

Positive Client Adoption & Feedback

The system is currently being rolled out to all clinical staff, with active training sessions underway. The initial response

from hospital leadership and early adopters has been overwhelmingly positive.

"The feedback from hospital administration has been extremely positive, describing the new platform as a 'game-changer' for their daily operations and

expressing great satisfaction with its potential to enhance patient care."

Delivering on Core Value Propositions

This successful launch validates our initial design hypothesis. The platform is now actively helping the facility centralize

key operations and enhance patient safety โ€” directly fulfilling the core goals set at the start of this year-long

engagement.

Reflection & Future Vision

What I Learned

This year-long project was a profound learning experience in designing for a complex, high-stakes environment. A key takeaway

was the importance of establishing a shared language with both clinical users and engineers early on. Techniques like role-

playing and a robust Design System are not just 'nice-to-haves' โ€” they are essential for translating ambiguous needs into a

beloved product under strict HIPAA standards.

What I Would Do Differently

If I were to tackle this project again, I would advocate for involving the engineering lead even earlier โ€” in the user research

phase. This would have allowed us to identify technical constraints sooner and align on feasibility more efficiently, saving

valuable time during development sprints.

Next Steps

My work on the foundational platform has paved the way for several exciting future expansions:

1.

Integration with Financial Systems (Billing & Insurance): Expand from clinical operations into the administrative workflow by

developing an integrated payment and billing system, further solidifying VHS as the single source of truth for all hospital

operations.

2.

Exploring Telehealth Capabilities: Incorporate telehealth functionalities โ€” remote consultations, digital prescriptions, and

online patient follow-ups โ€” to evolve VHS from an operational tool into a comprehensive patient care ecosystem.

Takeaway

"Designing for healthcare means designing for trust.

Every decision โ€” from information hierarchy to

alert colours โ€” carries real consequence for staff

and patients alike."
