DEFINING = UNDERSTANDING
There’s a lot of information and data that the CDC website is trying and needs to convey. Although the information was categorized, it was hard to easily recognize them and navigate through to find what is needed. We tried to define the wireflow by searching the trends and top traffic pages with the CDC website in order to see what people most seek when coming to their website.

Why users go to CDC website

Fact Pages about Diseases (Lyme, Influenze, Strep Throat, Meningitis…)
BMI Index (Adult and Children)
STD Facts and Disease Facts
Disease Fact Pages
Topical / Current Events
Natural Disasters / Emergency Preparedness
Prevention
Linked from Other Sites

Top Keywords that link back to CDC

Calculating BMI

With given tasks to the users, we created a wireflow mapping the current user flow.
HEURISTIC EVALUATION
The heuristic analysis showed the need for both internal informational architecture and UI. Restructuring the information hierarchy and having a well-organized look will reduce a significant amount of confusion.

The color accessibility check was needed. Most color contrasts passed except certain shades, such as green. Because of various information services and abundant information resources, smaller texts needed to contrast with the background so that the contents could be clear and easily read. Paying careful attention to the suitable use of negative space can support the visual hierarchy. With the evaluation, we listed the important features and categorized them in a prioritization matrix.
STRUCTURING

Consistency, Clarity, and Unity

These were the main concerns when building the style guide. All the elements specified in the Style Tile must easily guide the user to what they’re searching for.
