How did reliable mechanical cooling shift the focus of quality control management in logistics?

From managing the external environment to managing the internal system

The advent of reliable, machine-driven mechanical refrigeration, pioneered by figures like Jones, fundamentally altered the approach to logistics quality control. In the era of natural ice preservation, the primary focus of logistics management was largely centered on securing and managing the external environment—ensuring enough ice was harvested, stored properly, and replenished en route. Once cooling became consistent and machine-driven, the system's integrity depended on the reliability of the transport vehicle itself. Consequently, quality control shifted its primary focus to managing the internal system of the transport unit, including monitoring the mechanical components and sensor data, as a mechanical breakdown or sensor malfunction could now lead to catastrophic product loss.
