What has caused more Supply Chain disruptions in recent years?

Rising volatility comes from multiple sources: globalized networks, constrained capacities, shifting consumer behavior, inflation and cost pressure, and more frequent logistical shocks. Many companies also discovered that static planning systems and manual processes are not resilient when uncertainty becomes constant. The structural lesson of the last few years is that volatility is now a baseline condition rather than a temporary exception. Planning approaches built on stable demand and reliable lead times age quickly in that environment, while approaches that model uncertainty explicitly hold up far better. The organizations that adapted earliest tend to combine probabilistic forecasting, dynamic buffers and scenario simulation as standard practice rather than crisis tools.
