Public-health design project

SOP recorded: follow the user-centered design cycle: define users, list needs, prioritize features, sketch a wireframe, then plan a usability check.

Target users and the variables shaping their needs: language, data access, age, and health literacy all change what a user needs.

Persona 1, 'Rosa, 58': limited data plan, prefers Spanish, worried about exposing family. Top need: know if it is safe to seek care without traveling far.

Persona 2, 'Jamal, 19': smartphone-fluent, no car, relies on public transit. Top need: find the closest open mobile site and its hours.

Prioritized feature list (highest-urgency first):

• Live clinic and mobile-site map with wait times.
• Language toggle (English and Spanish).
• Low-bandwidth text-only mode.
• Symptom self-check with 'when to seek care' guidance.

Wireframe (two screens, low fidelity):

• Screen 1: big 'Find care near me' button, language toggle, last-updated stamp.
• Screen 2: map list of sites with wait time and hours, one tap to directions.

Usability-check plan: have three classmates find the nearest open site in under 30 seconds; count taps and note confusion points.

Limitation: our personas are composites we invented, not real users, so the feature priorities are our best guess until we test with actual community members.
