In total, we conducted 21 sessions with internal staff and external users, including past appellants, lawyers, case management officers, call centre staff, scheduling staff, and adjudicators. The sessions with past appellants were far more complex and emotionally charged than anticipated. Participants shared deeply personal stories involving medical crises, mental health challenges, substance use, and significant financial strain. It quickly became clear that the website was not their primary concern; many were navigating some of the most difficult periods of their lives. Recognising this, we adapted our approach in real time by incorporating trauma-informed practices, reassessing our facilitation methods, and broadening our analysis beyond usability. Through affinity mapping and systems analysis, we identified root causes such as confusion around process roles, inconsistent information, and critical gaps in financial, informational, and staff support. To further understand these dynamics, we created a service design blueprint that mapped internal staff workflows and touchpoints, revealing how operational processes directly shaped and sometimes constrained appellants’ experiences.
