| | SWIM: State of the Art in Workflow |
 | | Workflow is a domain that has evolved from several fields, business management, modeling, simulation and, to a lesser extent, planning and control. |
 | | The workflow engine must maintain all the knowledge and internal control data to identify the states of each of the individually instantiated activities, transition conditions, connections among processes (for example, parent/child relationships), and performance metrics. |
 | | Workflow failures may result from a processing entity not completing a task correctly or on time, or by an unexpected event in the environment. |
