Approval Groups are groups of authorized approvers who are notified when particular work items are submitted.
For example, when a worker submits a Time Sheet for their hours worked, the Time Sheet must be approved before it can be invoiced.

Throughout the lifecycle of SOW creation and management there are a variety of times where an organization may want, or need, to configure approval groups, such as when approving a newly created SOW or revising the terms of an existing one, updating fees or other characteristics, or when an SOW Worker is added to a project.
Configuring approval groups for SOWs and SOW workers is different from the approval groups used for the Contingent module. Therefore, approval groups for the Services module must be created separately.
