What is the primary purpose of the 'Quick Task' in process models?

The primary purpose of the 'Quick Task' in process models is to show as a related action on process-backed records. This functionality allows users to easily access tasks that are relevant to the record they are viewing, facilitating seamless interaction within the application. By associating quick tasks with specific records, users can perform necessary actions without navigating away from their current context, thus improving efficiency and workflow.

Other options present valid functionalities but do not capture the essence of what 'Quick Task' is designed for. While enhancing user engagement, automating decision-making, or tracking user performance are all important aspects of process management, they do not specifically define the role of quick tasks in the context of process models. Quick Tasks are primarily a means to provide immediate access to actions related directly to a specific process-backed record, thus streamlining user interactions in Appian applications.
