Queue Management

You can use the Queue to assign tasks to groups of actors and to include queues comprising participants as part of their process. The queue feature is generally used by the AVEVA Work Tasks process administrators and owners. The queue feature provides a greater level of flexibility in the assignment of tasks to the participants.

Queue Features

Queue Management has the following features:

• Supports push-pull patterns

• Specify Role or User as Participants

• Access rights for Role or User

• Queue level escalations

• Allocate tasks to actors automatically or manually

You can perform the task allocation on the following basis:

• Automatic: The allocation is done automatically using defined algorithms. The assignment is done using the Round Robin, Random, or Least Used methods. This push pattern is the default setting.

• Manual: The task allocation is done manually. In this case, you can view and pick a task from the queue. Alternatively, the users can be allowed to use a button in the Work items list to get the next available task in the queue. In this case, the users cannot view the tasks in the queue but can click the button to get the next available task in the queue. This is the "pull" pattern as opposed to the "push" pattern where the queue assigns tasks.

• Combination: The task allocation is done using a combination of automatic and manual methods.

Significance of Queues

You can use Queues in workflows to set the recipient(s) of activities in the following manner:

• Assign tasks to resource(s) directly using the Assign Actor(s) property

• Assign tasks to Queues using the Assign Queue(s) property

• Assign tasks using both properties.

  Note: If both the properties are set, both the resource(s) and the queue(s) are assigned the task directly. The resource getting the task from the queue will have to act on it. In each case, the respective escalation or timeout setting will apply.
