Project Details
Client: Backyard Co., Ltd
My Role: Lead Product UX/UI Designer (Scrum Environment)
Timeline: 2 Months
Platform: Dashboard / Web ApplicationMonths
Key Focus: Enterprise Tool UX, Cognitive Load Reduction, Word-Tagging Workflow, Data Visualization
Overview
— Challenge: The legacy version of the tool was too complex and time-consuming for its primary target group—teachers aged 40–60. The original word-tagging feature lacked intuitive usability, and the platform failed to generate the visual data insights and comprehensive reports required by educators.
— Solution: Re-engineered the platform’s site map and user interface by applying user-first methodologies. Transformed a complex, text-heavy dataset environment into an accessible, visual-first dashboard that streamlines the annotation process and clarifies reporting.

Case Study Highlights
— The Challenge: Designing for educators aged 40–60 required drastically minimizing cognitive load and technical friction. The legacy word-tag featured was notoriously rigid and frustrating to navigate, which hindered teachers from efficiently parsing text data or visualizing key template statistics.
— The Process (The Strategy): Re-arranged the information architecture based on core user pain points. Collaborated within a cross-functional Scrum environment alongside Product Owners, Developers, and Data Scientists. Managed design delivery through iterative phases—from low-fidelity wireframes to functional prototyping and rigorous usability testing—while tracking execution in JIRA and WorkChat.
— The Solution & Impact: Delivered a refreshed, highly scalable UI equipped with accessible, color-coded pickers for word tagging and clean data-visualization widgets (such as bar charts for tag distributions). The redesign eliminated critical UX bottlenecks, shortened task completion times, and empowered educators to manage complex annotations effortlessly.
