This section covers my coursework for UXR223, focusing on how qualitative and quantitative research methodologies provide the foundation for evidence-based design. From conducting user interviews, surveys, and focus groups to running usability testing, card sorting, and digital analytics, these projects explore how to uncover authentic human needs across every phase of the product lifecycle. Grounded in rigorous data analysis, ethical research practices, and persona development, these briefs investigate how to synthesise complex user behaviours into actionable insights, ensuring digital solutions are backed by real human feedback rather than assumptions.
