Time-Based Workflow Queue.
Explanation:
Workflow management systems can be defined as a strategic software application or program designed to avail companies the infrastructure to setup, define, create and manage the performance or execution of series of sequential tasks, as well as respond to workflow participants.
An example of a work management system is Salesforce.com.
In this scenario, Universal Containers created a Time-Based Workflow rule that sends a follow-up email to the customer two days after a Case is closed. The System Administrator wants to verify that the workflow functions correctly. Hence, the queue which the System Administrator should view to monitor pending Workflow Actions is the, Time-Based Workflow Queue because it will remain available to be viewed until the Workflow Action is executed or the record no longer matches the triggering criteria.
