Supply chains increasingly operate under conditions in which disruption emerges through the interaction of multiple pressures rather than from isolated events. Escalation in such contexts is shaped by accumulation, cross-domain propagation, and timing effects that challenge conventional representations of risk and resilience. While significant research on resilience has been developed over the last two decades, much of this work remains grounded in event-centric or probability-based approaches. These offer limited analytical visibility into how interacting pressures reshape exposure and sustain escalation over time. Recognising this gap, the authors develop three tools for examining supply chain resilience under polycrisis conditions: 1) the Stress–Trigger–Crisis (STC) taxonomy distinguishes background pressures from initiating disturbances and crisis states; 2) propagation pathway analysis traces how disruptions spread across physical, informational, financial, and relational domains; and 3) the Exposure-Controllability tool compares how vulnerability and influence are distributed across supply chain structures. Using a case example from a leading logistics player, this paper reveals the application of these tools. Conceptually, the paper advances a system-level representation of resilience under interacting pressures. Practically, it provides a repeatable method for linking diagnostic analysis to organisational action.
