Having permission control feature of "QA Check Override" will help QA process quality.
Because some case, we use "QA Check – Check Segments Confirmed" workflow step.
But beginner TMS user does not know that unconfirmed segment will not update TM if TMS set up that way.
Instead, he/she use this QA Check Override then TM will not updated. That result QA check bypassing unintentionally.
