Simple workflow is generated by an Alfresco space that has a defined workflow content rule. The content rule dictates how the content entering, leaving, or currently residing in the space is managed.
Advanced workflow is any workflow constructed using the Alfresco embedded workflow engine. You can start an advanced workflow with the Start Advanced Workflow Wizard or as part of Web Content Management (WCM). Advanced workflows are defined in your development environment or the Alfresco Workflow Designer.
Alfresco includes two out-of-the-box workflows: Adhoc Task (for assigning a task to a colleague) and Review & Approve (for setting up review and approval of content). These are both basic examples of advanced workflows. In both examples, the content items are attached to the workflow.
In WCM, the workflow is configured for a web form associated with the web project and/or workflow configured as part of the overall web project. The Submit process in WCM is a complex example of advanced workflow that moves content through review, approval, and publishing actions.
Tasks resulting from advanced workflow are managed in your personal dashboard (My Alfresco).
