What feature allows you to streamline approvals in Appian processes?

The feature that streamlines approvals in Appian processes is the Approval Nodes. These nodes are specifically designed to facilitate the approval workflow within a process model. When incorporated, they allow process participants to review, accept, or reject requests in a structured manner, ensuring clarity and efficiency in decision-making.

Approval Nodes help standardize the approval process by providing a designated mechanism for capturing decisions, and they come with integrated options for comments and rationale, which can enhance communication among stakeholders. This not only speeds up the decision-making process but also adds a layer of accountability by tracking who approved or rejected a request and why.

In contrast, while task assignment is important for directing work, it does not inherently provide an approval workflow. Sub-processes can be useful for organizing complex workflows, but they do not streamline approvals by themselves. Notification alerts serve to inform users about tasks or changes but do not facilitate or manage the approval process directly. Therefore, Approval Nodes clearly stand out as the appropriate feature for streamlining approvals within Appian processes.
