A workflow is a collection of related, structured activities that produce a service or product that meet the needs of a client. These processes are critical to any organization as they generate revenue and often represent a significant proportion of costs. As a managerial approach, the business process management considers processes to be strategic assets of an organization that must be understood, managed, and improved to deliver value added products and services to clients.

The Workflow feature is a document life-cycle tool that assigns a business process to a collection of documents. The administrator creates and adds workflow templates based on his organizational business processes. Any system user may be involved in a workflow on a document. Some documents, such as a purchase order, may have complex workflows that involve several people inside your organization.

The workflow consists of [Tasks] and [Transitions], that a collection of documents must pass through before the workflow can be considered completed.

• Task: can be defined as a stage in a document’s life- cycle, such billed, or draft. Each workflow has a single start task, which is the initial task for any document in a workflow
• Transition: defines how documents move between tasks in the workflow. Transitions are actions that move a document to the next task

The workflow engine takes care about notifying the required persons when tasks must to be worked, so it is important to correctly configure the connection to your SMTP server.
