<h3>Background and Importance</h3> The consolidation of four hospitals into a single campus of 986 beds with 25 operating rooms prompted the integration of automated dispensing systems–unit-dose clipping, over-packaging machines, robotic storage, rotating cabinets, and drop-to-light reconciliation stations–managed through a warehouse management system (WMS). Despite planning and prior evaluations this integration was met with early operational challenges and reliance on manual overrides. <h3>Aim and Objectives</h3> Those challenges motivated the creation of a risk assessment task force to ensure safe and reliable medication restocking in the Interventional and Operative Technical Platform (PTIO). <h3>Material and Methods</h3> A system-oriented Failure Modes, Effects, and Criticality Analysis (FMECA) was conducted by a multidisciplinary working group composed of 3 pharmacists, a technician, and a quality specialist. Five plenary and one individual scoring sessions allowed the group to identify and describe 25 failure modes across five sub-systems using mind mapping and some ‘Healthcare Failure Mode and Effect Analysis’ (HFMEA) principles, including the detection of Single Points of Failure (SPFs). A locally validated criticality grid guided quantitative scoring and the prioritisation of risk-reduction measures <h3>Results</h3> Twenty-five failure modes were mapped; seven reached intermediate or high criticality. Four SPFs were highlighted: two related to discrepancies between digital and physical inventory, one storage-robot malfunction, and one over-packaging bottleneck. Nineteen corrective actions were defined. After one month, twelve were implemented, five were in progress, and two awaited initiations. Average risk scores for inventory SPFs decreased from 14 to 7.3, while the robot and over-packaging SPFs dropped from 8 to 4 and 15 to 6, respectively with a score below 8 defined as ‘low risk.’ <h3>Conclusion and Relevance</h3> Applying FMECA prior to full automation facilitated the identification and mitigation of critical vulnerabilities in a complex medication circuit. Our study also suggests that engagement of IT specialists dedicated to the pharmacy is recommended to address unresolved high-criticality issues and improve responsiveness in an ever more technical environment. Although resource-intensive, targeted FMECA enhances change management, supports staff engagement, and strengthens patient-safety outcomes. <h3>Conflict of Interest</h3> No conflict of interest
