What is the function of a fork node in process modeling?

The function of a fork node in process modeling is to mark the start of concurrency. When a fork node is encountered in a process or workflow, it allows the flow of control to split into multiple parallel paths. This means that once a fork node is reached, the process can initiate several activities simultaneously. This is essential in scenarios where different tasks can occur at the same time, maximizing efficiency and allowing for more complex workflows.

Fork nodes are particularly useful in modeling scenarios involving concurrent operations, allowing for better representation of real-world processes where multiple actions can occur independently and in parallel. Understanding this concept is crucial for accurately depicting processes and ensuring that the modeled workflow reflects the intended operations effectively.
