Which of the following are steps to configure a user input task?

The correct choice encompasses all the essential steps involved in configuring a user input task in Appian. Each step plays a critical role in ensuring the task is set up correctly for user interaction and data handling.

Configuring a dynamic display name allows the task to be more user-friendly, giving it a context-specific label that can help users understand what action they are taking. This enhances the user experience by providing clarity.

Setting up variables is crucial for enabling data communication between the process and the user interface. This allows for the retrieval and manipulation of data as the user interacts with the input form, ensuring that user inputs are captured and can be processed effectively.

Adding the interface as the node's form connects the user input task to the specific UI designed for it. This step links the graphical components with the task, allowing users to see and interact with the form that presents the fields and options necessary for the task.

By integrating all these components, the user input task becomes a cohesive element within the workflow, enabling proper data management and user interaction. Hence, recognizing the significance of each of these steps affirms that the answer is indeed all-inclusive.
