Just-in-time (JIT) manufacturing relies on precision timing and real-time data exchanges between production systems and external suppliers. Network latency can directly impact the efficiency and viability of such a system. For this reason, the architect must prioritize a network design that ensures minimal delay and rapid delivery of application and sensor data.

According to CCDE v3.1 design principles, when latency is tied directly to business outcomes (e.g., manufacturing workflow dependencies), the network must be designed with a focus on:

End-to-end low-latency infrastructure

Predictable jitter and delay control

Application prioritization mechanisms (QoS)

High availability and redundancy

This allows the manufacturer to optimize production throughput while reducing delays caused by communication lag with external component providers.

Why other options are incorrect:

A. Automation helps with operational efficiency, but it does not directly ensure low-latency communication.

B. Zero Trust is a security model, not latency-related.

D. Modularity is about design structure, not latency performance.
