Concern worldwide is a global humanitarian organization that aims to end extreme poverty. The project goal was to identify areas of usability improvement, evaluate if the designs were consistent with the user’s mental models, and learn about the donation patterns. A moderated user testing was conducted on their medium-fidelity wireframes for the responsive website as they are currently undergoing a redesign process. On the basis of the usability testing results, four recommendations were given to increase the donation flow and build greater trust amongst the users.
