A ZopeProduct providing workflow, designed from the beginning to be as simple, flexible and customizable as possible. The basis is an activity based workflow concept. It's fully integrated into Plone and supports a wide range of Workflow patterns described on the Workflow Patterns Homepage.
Content types can easily connected to workflow process instances like portal types, user permissions etc. AlphaFlow comes with its own XML based process definition language. Workflows process definitions can be assigned per instance level rather than per class or portal type level (like in DCWorkflow).
Process definitions contain activities like notifications, decisions or tasks. An instance of a process definition is an individual object with a different amount of work items including different states. Just to note, that the activity instances are called work items, because the most users can visualize work items better than activity instances.
