CDPH Website Redesign
Madoka Yoshiki Franzen, 2025 Showcase
CDPH Website Redesign: For my ISDA 131 project, I redesigned the California Department of Public Health website to enhance the usability, findability, and accessibility for its diverse audience. I started with an information architecture (IA) audit that revealed vague persona-based labels, deep, redundant hierarchies, and fragmented search paths. To gather user insights, I conducted a closed card sort, competitive benchmarking, and a review of WCAG 2.1 accessibility standards.
Using a closed card sort, competitive benchmarking, and a WCAG 2.1 accessibility review, I organized the content into five task-oriented top-level categories and established optimal 2–3 level hierarchies. I created high-level and low-level sitemaps that consolidated professional licensing workflows under a single structure with task-based entry points. The prototype introduced key features such as a prominent search bar, wizard-style navigation steps, collapsible clusters, and accordion panels to display content on demand.
The redesigned homepage includes a trending topics carousel, consistent typography, language toggle options, and an ARIA-compliant layout. This project culminated in an interactive prototype and presentation, showcasing how a user-centered approach to information architecture can simplify complex government content.
Madoka Yoshiki Franzen: “I am a senior majoring in Information Science and Data Analytics, originally from Japan. Before taking this course, I didn’t have a clear understanding of “information architecture,” even though I often found myself frustrated with certain websites and felt that they hindered my progress. Throughout this course, I’ve learned how important clear labeling, logical hierarchies, and accessibility standards are for creating effective digital experiences. Going forward, I plan to enhance my information architecture skills, conduct usability testing, and advocate for user-centered design in my future projects.”
