Case study — 02

Sharity

Social giving, designed for trust — a donation platform concept that tackles donor drop-off by making impact tangible and giving social. Users donate easily, partner with friends and brands for social good, and earn rewards for sustained generosity.

Sharity — donating made easy, impact made visible, generosity made social.

Interface visuals refreshed in 2026 to current craft standards. The research, process, and findings below are from the original project.

01 The problem

People don't just fail to donate — they stop donating. The research kept surfacing the same three reasons: personal financial strain, poor communication (never seeing what a donation achieved), and lack of trust (no transparency into where money actually goes).

That framed the real design challenge. It wasn't "make a prettier donate button." It was: how might we design a platform that makes donating easy without financial burden, keeps people motivated to continue, and makes a real, visible difference for the causes they support?

02 Behavioral grounding

Before sketching anything, I dug into secondary research on what actually moves people to give — and keep giving. Two findings shaped the entire concept:

Research that shaped the design

  • Tangible details drive donations. Across three experiments (Organizational Behaviour and Human Decision Processes), describing a charity's interventions in concrete detail increased donations — because donors believed their generosity could actually affect the problem. Design implication: show impact concretely, not abstractly.
  • Generosity cascades. Research on social networks (Cooperative Behaviour Cascades in Human Social Networks) found one generous act can inspire generosity three degrees removed — a single person influencing dozens they've never met. Design implication: make giving social and visible.

Those two principles — transparency of impact and social mechanics — became the concept's backbone: partner with friends, team up with brands for social good, and earn rewards that reinforce the habit.

03 Defining the user

I worked from a proto-persona, Saadia — a Chartered Accountant who wants the altruistic feeling of helping, but is wary of how much of a donation disappears into administration and operational costs. She's looking for a platform that shows exactly how funds are deployed while maximizing impact.

I'll be direct about the constraint: my interview sample was 5 people from similar backgrounds and beliefs — not representative of all donors. Rather than dress that up as validated personas, I used a proto-persona explicitly and let the behavioral literature carry the generalizable weight. Naming your evidence limits is part of doing research honestly.

04 Exploration

Journey mapping first, then sketches and crazy-8 exercises to explore broadly before converging on a lo-fi prototype for testing. The core flows: discovering causes, starting a donation, tracking impact, and redeeming rewards.

05 Testing — where the design broke

I ran unmoderated usability testing with 7 participants (ages 25–60, each donating to charity at least twice a year) against the core flows. The results were humbling in the best way — they found real breaks:

Critical findings

  • 3 of 7 participants tapped "favourite causes" instead of "donate now" when asked to start a donation. They eventually completed the goal, but the detour added 2 extra steps and real confusion — the primary CTA wasn't reading as primary.
  • 4 of 7 struggled to navigate to a campaign and back to redeem a reward — a critical error for 2 of them. The redemption flow required users to know they had to go back a page; they didn't.

06 Iteration

Both fixes were structural, not cosmetic. For the donation flow, I redesigned the home page around two unmistakable primary actions: begin a donation, or track a donation's progress — no competing labels, no ambiguity about where to start. For rewards, I added redemption directly inside the campaign page, so users never have to navigate away and back to complete the task. In-context actions beat navigational ones.

The hi-fi design carries a high-contrast visual style to WCAG 2.1, with the home page rebuilt around the donation flow — the product's most critical functionality — and transitional animations that make pop-up menus feel responsive and alive.

"In-context actions beat navigational ones — don't make users leave the moment to complete it."

07 Outcome & reflection

Sharity landed as a validated concept: a donation flow users can start without hesitation, impact tracking that answers the trust question, and a reward system that survived contact with real users. The two critical errors found in testing were designed out, not documented away.

What stayed with me: secondary research is a legitimate design material — behavioral findings gave this concept a spine that pure intuition couldn't. And the proto-persona decision reinforced something I still practice: be explicit about what your evidence can and can't support. It makes the work more trustworthy, not less.
