What is one consequence of relying heavily on suppliers in a JIT system?

In a Just-In-Time (JIT) system, companies strive to minimize inventory and rely on suppliers to deliver materials and components exactly when needed for production. This dependency can lead to increased risk of supply chain disruptions. If a supplier encounters delays, quality issues, or other problems, the manufacturing process can be significantly impacted, resulting in halted production lines and potential loss of sales.

While relying on suppliers can simplify some operational processes, it inherently introduces vulnerability. Natural disasters, political instability, and logistical challenges can all disrupt the supply chain. This reliance means that any disruption in the supplier's ability to deliver can have immediate consequences for a manufacturer that operates with minimal inventory levels.

The other options, such as improved communication, lower transportation costs, and enhanced product quality, may not necessarily result from heavy reliance on suppliers. In fact, the need for urgent communications and quick resolutions may arise from the very risks brought on by the reliance on external suppliers.
