WSS 3.0 - WorkFlows

A workflow allows you to attach a business process to items in Windows SharePoint Services 3.0. This process can control almost any aspect of an item in Windows SharePoint Services 3.0, including the life cycle of that item. For example, you could create a simple workflow that routes a document to a series of users for approval.

Workflows can be as simple or complex as your business processes require. You can create workflows that the user initiates, or workflows that Windows SharePoint Services 3.0 automatically initiate based on some event, such as when an item is created or changed.

Windows SharePoint Services 3.0 workflows are made available to end-users at the list or document-library level. Workflows can be added to documents or list items. Workflow can also be added to content types. Multiple workflows may be available for a given item. Multiple workflows can run simultaneously on the same item, but only one instance of a specific workflow can run on a specific item at any given time. For example, you might have two workflows, SpecReview and LegalReview, available for a specific content type, Specification. Although both workflows can run simultaneously on a specific item of the Specification content type, you can't have two instances of the LegalReview workflow running on the same item at the same time.
