Project A - Body Temperature Monitoring

‍

Aim

As a Product Manager for this project, I aimed to simplify and enhance the workflow of healthcare professionals using an IoT product design. I carried out user research to gain insights into their daily work routine. Previously, each caregiver had to measure the body temperature of 40 residents within a 90-minute timeframe, using forehead thermometers and recording data manually on paper. The target users had varying levels of experience with digital products. It's critical to note that "Measurement" and "Monitoring" are different behaviours. Users must adapt to the new IoT app's mental models for monitoring residents' body temperature, which requires user-friendly UX designs.

User Research

During the design process, encompassing the stages of "Discovery" and "Interpretation", I utilised Contextual Inquiry, Shadowing, and User Interview methods to capture the user's needs and potential. As a result, I identified an opportunity to develop an improved service that caters to the users' requirements more effectively and precisely, as demonstrated in the service blueprint.

‍

UX Research & Design

To start designing the user interface for the product, I first conducted thorough UX research to identify user behaviours, interactions and workflow with the app. Using this research, I created a flowchart and wireframe to guide the following design process.

Users' Workflow

Interaction (Users’ Behaviour)

‍

Flowchart and Wireframe

I conducted a comprehensive analysis of the information architecture and user behaviours within the app. Based on this analysis, I strategically positioned the relevant information and action buttons on each page, ensuring optimal usability and intuitive user interactions.

UI Design for Mobile App

UI Design for Web App

The Web App version designed for reviewing body temperature monitoring data prioritises effective visualisation of body temperature trends at varying time scales, including daily, monthly, and yearly. The primary focus of the design is to present valuable insights into residents' body temperature patterns, with the ultimate goal of improving the quality of healthcare in facilities.

‍

Optimisation

After conducting a usability test with seven foreign carers who performed five tasks, it was found that the version 1 prototype had an issue in which users struggled to recognise whether the chips were connected successfully or not. This issue arose because the visual indicator relied solely on changes in text positions (chip names), which was insufficient for the users to determine the connection status accurately.

A/B Testing

In order to optimise how users can easily recognise the chip connection status, I redesigned the "Pairing a Body Temperature Monitoring Chip" stage, creating two different solutions for the pairing process.

‍

Solution A

‍

Streamlined the process by immediately returning the user to the chip list after connecting to a smartphone. The devices list displays the updated count of connected chips, indicating the addition of one more chip.

‍

Solution B

‍

Maintained the same step count as the version 1 prototype while incorporating a "snackbar" notification at the bottom of the screen. This notification confirms the successful connection of the newly added chip to the smartphone.

‍

Results

To evaluate the effectiveness of these design enhancements, the same seven foreign caregivers who participated in the Usability Testing were invited to participate in an A/B test. The results showed that the inclusion of the "snackbar" at the bottom of the screen improved comprehension for users, offering them a sense of controllability and feeling more manageable about the situation, thus enhancing the overall satisfaction of the system.

Reflection

As a Product Manager at Jubo Health, I successfully managed and designed two significant projects that reflect my dedication to user-centric designs and optimised user experiences.

The first project focused on developing an IoT app for body temperature monitoring to simplify healthcare professionals' workflows and improve the user experience. Through strategic discovery, web and mobile app design, component-based UI-kit creation, and meticulous dashboard UI redesign, I successfully managed the product from concept to launch. I conducted usability testing and A/B testing to refine the design and enhance user satisfaction.
