<p>The IHE Departmental Workflow  is centrally monitored by the Department System Scheduler/ Order Filler, but its execution may be managed by distributing further control into two levels.</p><p> The first is a set of one or more Worklist managers that are responsible for management of worklist items used to control the activities within a certain phase of a requested procedure. Worklist Managers are also responsible for conveying phase status and information availability to the Workflow Manager and other peer Worklist Managers. The Worklist Manager s method to generate worklist items is not explicitly described by IHE. Currently it is assumed that a Worklist Manager uses internal logic to generate worklist items. Generation of worklist items directly triggered by an actor other than the Worklist Manager is not defined in this concept paper, and would require additional communication between this other actor and the Worklist Manager. </p><p>The second level is a set of workflow participants that are entirely in charge of performing specific procedure steps. This level is defined in detail in the existing individual workflow profile already included in the IHE Radiology Technical Framework and is not described further in this paper.
