To validate the effectiveness of the redesigned interface, multiple rounds of usability testing were conducted with a diverse set of internal stakeholders and real-world users. Each session provided actionable insights that guided iterative refinements, particularly in information hierarchy and navigation flow. These refinements contributed to a noticeable reduction in user hesitation when interacting with key sections. By incorporating direct user feedback into each iteration, the design evolved to feel both intuitive and purpose-driven, reinforcing the importance of a data-informed, human-centered design process.
