Fragmented systems waste time
Essential services were split across multiple sites with inconsistent UIs and separate logins, creating inefficiency and confusion.
University members must visit various unrelated sites to access basic services.
This fragmentation creates a disjointed and inefficient user experience.
To understand actual needs, I analyzed usage patterns and gathered feedback from students and staff
Research revealed that students frequently encountered difficulties navigating multiple services, struggled with inconsistent interfaces, and needed quick access to key campus information.
Based on insights, key principles were defined to guide Hoit’s UX and UI
These principles shaped Hoit’s interface and interactions:
frequently used services appear at the top in a scrollable menu, urgent announcements and events are immediately visible, and secondary content remains accessible without clutter.
