UX ENHANCEMENTS CASE STUDY

Self Checkout Flow

This project focused on improving the usability and efficiency of a business application by applying a user-centered design process. Through in-depth research, iterative testing, and strategic design enhancements, the goal was to simplify workflows, improve navigation, and optimize feature accessibility. By leveraging affinity mapping, wireframing, and prototyping, the final solution delivered a more intuitive experience that balanced business needs with user expectations.

Primary Research

To understand user pain points and workflow inefficiencies, I conducted stakeholder interviews, user surveys, and contextual inquiries. Observing real-world interactions with the application helped uncover navigation challenges, feature discoverability issues, and workflow redundancies, setting the foundation for an informed design approach.

"I shop here all the time, but every time I use self-checkout, I have to go through multiple steps just to find my account. Why isn’t there a quick login option right on the main screen?"

"I just want to add my loyalty points, but finding my account takes too long. Scanning my phone should pull it up instantly instead of making me type in my email every time."

"I have the store’s app, but when I’m at self-checkout, there’s no clear way to link my account. It should sync automatically or at least give me a QR code to scan instead of making me search for my login."

Design Research & Solution Ideation

With insights in hand, I explored solutions through heuristic evaluations, user journey mapping, and rapid sketching. By refining workflows and prioritizing core functionalities, I ensured the redesign aligned with both business objectives and user expectations, emphasizing clarity, efficiency, and ease of use.

Wireframe Modifications

Low-fidelity wireframes allowed for early validation of structural improvements, refining navigation and feature accessibility. Iterative testing with users helped adjust layouts, simplify interactions, and create a more intuitive experience before moving into higher-fidelity prototypes.

Low-Fidelity Testing & Iterative Improvements

Through task-based usability testing, I gathered feedback to refine and iterate on key design decisions. Addressing usability friction through A/B testing, micro-interaction enhancements, and workflow optimizations ensured a more seamless, user-friendly experience that balanced business goals with user efficiency.

Design Integration & Prototyping

With validated wireframes, I transitioned into high-fidelity prototyping, integrating branding, visual hierarchy, and interactive elements to create a polished user experience. Prototypes were tested in real-world scenarios to assess usability, responsiveness, and task efficiency, ensuring a smooth handoff for development with clear documentation and design specifications.
