What is the "Completion" Stage of a WorkGroup ?

The "Completion" Stage is the fifth and final stage of a WorkGroup which consists of checkboxes. In order to consider a WorkGroup as completed successfully all checkboxes must be checked.

Note that you might not be able to check all checkboxes because checkbox visibility in this stage depends on the role you have for this WorkGroup. For example, a user who acts as Client in a WorkGroup, can not check that Collaborator Professional is paid.
