Which feature enables business process owners to organize Flow Designer content into unified and digitized cross-enterprise processes via a digitized task board interface?

Flow Designer is used for building individual flows and automations, not for organizing them into a high-level cross-enterprise process with a task board interface.

Workflow Editor is an older tool for creating linear workflows and does not offer the digitized task board interface for cross-enterprise process management.

"Process Workflow Designer" is not a standard ServiceNow feature that matches the described functionality; Process Automation Designer is the correct tool.

Process Automation Designer is specifically designed for business process owners to organize and visualize complex, cross-enterprise processes using a task board interface, orchestrating various Flow Designer components into a coherent, digitized workflow for end-users.
