Synonyms

Queuing mechanism; Workflow scheduler

Definition

The mechanism that identifies and initiates the sequence for activities and work items are executed.

Key Points

A Scheduler initiates work assignments based on precedence relationships and the state of a workflow instance. A Scheduler is not a “queue” which is typically a set of work items or activities waiting to be scheduled, however, a queue of items may be managed by the Scheduler. The role of the Scheduler is to minimize queue time and optimize executive efficiency.
