For decades, the dominant paradigm in global logistics was lean manufacturing, a system predicated on the minimization of waste and the optimization of just-in-time (JIT) delivery. By reducing inventory levels to the absolute minimum necessary for immediate production, firms were able to free up capital and drastically lower warehouse holding costs. However, recent systemic shocks, including escalating geopolitical tensions and climate-driven logistical bottlenecks, have exposed the inherent fragility of this model. The absence of safety stock means that even a minor disruption in a single tier-two supplier can halt production globally. Consequently, many strategists now argue for a shift toward resilience-based logistics. In this view, inventory is not merely an idle cost but a form of insurance. While maintaining just-in-case stock increases overhead and potentially compresses short-term margins, it protects the firm against the catastrophic revenue loss associated with a total supply chain rupture. The strategic objective is no longer the lowest possible cost, but the most robust risk-adjusted delivery capability.
