I struggle to think of a single time when her expertise came in handy on a mission . That ' s because she ' s not a mission kind of crew member , she ' s a service and support crew member , one of the numerous people that make it possible for the front line guys and gals to do their job . Granted we don ' t see a lot of her actually providing counseling and therapy on screen to crew members for some reason the writers gave almost all of those scenes to Guinin , but that ' s presumably what 99 % of her work is about on a ship the size of the Enterprise she presumably supervises a whole department dedicated to just that as well . We do see her advising Picard a few times and assisting Riker with promotions and staff decisions in Lower Decks and fixing Barclay and whatnot .
