What is a key characteristic of a Script Task in a Process Model?

A Script Task in a Process Model is specifically designed to execute predefined code within the process flow without requiring any user interaction. This characteristic allows for automation of certain actions, calculations, or data manipulation directly within the process, which can be integral to the overall workflow. Script Tasks are commonly used to perform operations like variable assignments, complex computations, or data retrieval from external sources, all happening in the background while the process continues to run.

In contrast, the other options pertain to different task types or characteristics that are not applicable to Script Tasks. For instance, requiring user input pertains to User Tasks, which necessitate action from a person. Asynchronous execution refers to tasks that may occur independently of the main flow of the process, which is not a nature of Script Tasks, as they execute immediately within the process context. As for invoking other processes, this typically involves a Call Activity, which is intended for that purpose, whereas Script Tasks operate without such cross-process functionality.

Therefore, recognizing that a Script Task is fundamentally about executing code automatically highlights its unique role in process modeling within Appian.
