Volunteering lost its network effect

Post-pandemic, volunteer rates declined as people changed how they socialize. Organizations struggle to find helping hands; would-be volunteers struggle to find causes. CHANGEMATE explores how a mobile-first, user-centric platform could reconnect the two.

From screener survey to affinity themes

A screener survey to volunteer groups (12 responses) yielded 5 qualified participants for moderated interviews. Affinity mapping surfaced six recurring themes: transparency about events and organizations, engagement barriers, convenience, personalization, visibility of opportunities, and reward/gamification. A heuristic analysis of Engage, Nextdoor, and Eventbrite showed why traditional nonprofit tools lose to modern social products.

Nonprofits should be more accessible. A lot of places need help but don't broadcast enough, while some sites still have outdated listings.User interview

Two personas, three critical flows

User-story maps for two perspectives — the volunteer seeking credit-worthy local activities and the organizer recruiting for clients — defined the MVP: onboarding & account setup, applying for an opportunity, and creating an event. Napkin sketches were digitized into a clickable POP prototype for five guerilla tests, then iterated into wireflows, a full visual identity, and an accessibility-checked design system.

Test, iterate, repeat

Two rounds of moderated usability testing with 10 participants (7 active volunteers). Round one surfaced three critical issues:

Confusing sign-up and identity-verification steps during account creationround 1

Round 2: 100% completion — all 5 participants reported feeling more in control during account creation

Ambiguous options when applying for an opportunityround 1

Round 2: 100% completion on the application flow

Misleading language on key actionsround 1

Round 2: reworded; create-an-event flow reached 80% completion

Designing in a silo, learning to leave it

Research debunked my early assumptions about user preferences — a lesson in letting go of preconceptions. Resistance to a design element in testing, initially disheartening, became the project's most valuable iteration. And working solo taught me the opposite of solo work: the earlier you involve developers, stakeholders, and other designers, the better the outcome. Next for CHANGEMATE: gamification and auto-tracked volunteer hours.
