Project Duration: June ‘19 - Feb ‘20

Role: UX/UI Designer

Overview & Objective

  • Goal: Modernize a legacy plant-floor application to improve usability and production efficiency

  • Problem:

    → Existing system was built in an outdated language, causing frequent disruptions and user confusion

    → Inefficient workflows led to production slowdowns on the factory floor, resulting in overall loss of MFG profits

  • Solution:

    → Re-skinned the UI with a cleaner, more intuitive interface

    → Refined the overall user experience to streamline daily paint shop tasks

  • Key Outcome:

    → Improved clarity, speed, and productivity for plant floor personnel through a modernized, easy-to-navigate design

Business Context

  • The GM paint shop environment required a fast, seamless UX to support time-sensitive transactions

  • Workers often operated on tablets while wearing gloves, creating frustrating usability constraints

  • Existing system lacked speed and intuitive functionality, slowing down critical operations

  • Even a 5-minute delay could cost the company $150,000, translating to $7.8M in annual losses

  • Emphasizing efficiency, clarity, and responsiveness as top design priorities to minimize downtime in a high-stakes manufacturing setting

Discovery & Research

  • Conducted field research at the GM manufacturing plant in Arlington, Texas

  • Observed the production line workflow to understand user context and task flow

  • Interviewed plant floor manager to identify key pain points and usability challenges

  • Discovered issues with slow performance, tablet use with gloves, and UI scalability

  • Gained insights that reinforced the need for a fast, seamless UX for time-sensitive operations

Design Iteration Stage

  • After doing field research, I felt more confident in creating quick, iterative, high-fidelity designs based on user feedback

  • Some of these designs I shared with the client are shown below

Outcome & Impact

  • Conducted in-person usability testing, where users interacted with a clickable tablet prototype

  • Users were highly engaged — several noted it felt like a fully developed application, validating the realism of the design

  • Proposed touch-sensitive gloves to improve usability in glove-required environments, reducing task completion time by over 50%

  • Presented the designs showing significant time and cost savings — ultimately persuading leadership to move forward with full development

  • The implemented design doubled operational speed in the paint shop, showcasing the measurable business impact of strong UX
