Actions as Forms takes the power of forms and uses them as actions instead of the built in actions in RPM. Creating an actions/task process provides more flexibility with managing and reporting on subscription's actions list. Using a process to manage and track actions allows user to mass create/report/finish actions using form imports.
This use case is great if the built in actions feature in RPM is too limiting for managing the actions/task of your team members and can be a powerful tool for project management.
