How to get a glance at project status?
Based on interview findings, we defined the crucial information to get a glance project status.
The new platform went through many iterations before we had a shippable design candidate. As I unify platforms to one product, I added project lists and statuses, accessible data, and documentation ideas into the core wireframe and created a quick design prototype to test. After validation, I improved the design.
Based on user interviews, we identified the key information needed for a quick overview of project status.
As we unified multiple platforms into a single product, I introduced a centralized project list with clear status indicators, accessible data, and integrated documentation. I created rapid wireframes and a prototype to test the concept, then refined the design based on validation.
