The project focused on redesigning the 5DE app’s interface and improving key retail module to enhance the user experience for postal retail operations.
5DE was originally developed as a retail management platform for VNPost to support daily operations at post offices. However, the early version faced challenges such as inconsistent UI, limited scalability, and a lack of intuitive workflows for retail staff. The redesign was initiated to elevate the visual system, improve usability, and align the experience with modern retail standards.
At this stage, the team gathered and reviewed all available materials to better understand the existing system, including:
Current business workflows of the postal retail operations.
Previous design screens and navigation logic across key features.
Internal feedback from operational users.
This review process helped the team:
Understand the core business goals behind the product.
Identify key usability and experience issues to address in the redesign.
Before starting the redesign, the 5DE team provided documentation outlining the functional structure of the Retail module.
This map helped the my team gain a clear overview of how the system was organized — including product browsing, order creation, checkout, and post-purchase management.
Optimized for quick search, smart suggestions, and smooth navigation between results.
Improved product discovery through clear category navigation, quick sort options, and advanced filters for brand and price range — all designed for mobile usability and smooth interaction.
Simplified the structure of product details, ensuring users can explore specs, promotions, and related products with minimal effort.
Simplified layout and interaction patterns to support quick decisions and reduce drop-off during checkout.
I learned that designing new features isn't just about visuals, but also about managing scalable component systems. This helped me shift from thinking screen-by-screen to designing more structurally.
Due to missing steps in the early user flow, I often had to go back and adjust small details. It was a good reminder of how important early planning is to ensure consistent UI later.
