This study examines the effectiveness of human-centric versus design-centric sources in identifying pain-points, needs, and requirements that covers more categories of requirement checklists. Using data from a project focused on developing a camera holder for pediatric laparoscopic surgery, the research compares the types of pain-points, needs, and requirements identified through human-centric sources (HCS) and design-centric sources (DCS). Pain-points were gathered by (a) observing surgeries and interviewing surgeons (HCS) and (b) evaluating existing camera holders (DCS). From these pain-points, needs and requirements were subsequently derived. The study reveals that human-centric sources excel in capturing nuanced needs, while design-centric sources address broader pain points. These findings underscore the value of combining both human- and design-centric perspectives to achieve more comprehensive and relevant design outcomes.
