TaskRay comes with an optional validation rule that will prevent the completion of a task when its predecessor task is incomplete. Dependencies must be enabled in order for the validation rule to work.
With the rule activated, users will not be able to finish a task before the dependent predecessor is completed (moved to the Finished column). The tasks must have a dependency relationship between them.
