What can cause scheduled workflows not to execute at the exact specified time?

The execution of scheduled workflows can be impacted by the processing load on the NetSuite server. When there is high demand on the server—due to a large number of workflows being processed or extensive transactions—the system may prioritize tasks differently or queue them, which can lead to delays. This means that even if a workflow is scheduled for a particular time, heavy server activity can prevent it from executing exactly when intended. As a result, scheduled workflows might run later than the designated time rather than being executed as expected.

This highlights the importance of understanding server load when designing systems that rely on precise timing for workflow execution. It's essential for developers and administrators to consider system performance and scheduling when planning automated processes.
