Subflows are designed to be reusable components within Flow Designer in ServiceNow. They can be called from other flows, subflows, or scripts, making them versatile tools for streamlining processes and promoting consistency across various workflows.
By encapsulating a set of actions into a subflow, users can improve maintainability and efficiency. For instance, if a common task is needed across multiple flows, creating a subflow for it ensures that any updates made to that task only need to occur in one place, enhancing collaboration and reducing redundancy.
In contrast, triggers initiate flows based on specific conditions but are not reusable components. Actions are the individual tasks performed within a flow and do not represent a separate, reusable entity like a subflow. Flow logic helps control the flow execution paths but does not refer to a standalone, reusable component either.
Understanding the role of subflows is crucial for effective workflow design in ServiceNow, allowing for better organized, maintainable, and efficient automation solutions.
