The real problem with her is identifying in which decks she shines. At first glance you would love to put her in a rush deck, but that's not where she really helps. The fourth click let's you reliably fast advance your 2/3 agendas however to be of use she should survive for at least 3 rounds. Therefore you have to protect her with many/strong ice which you don't run since you want to fast advance.
The nice thing about her, more than any other executive, she demands an immediate answer. Trash her now or the corp will be miles ahead. Like SanSan City Grid you want to trash her right after you noticed her however she is also useful if you have established an R&D lock.
Therefore Director Haas sees best fit in glacier type HB where she uses the "scoring server" and you can fast advance your agendas. The other aspect about the executives in general is that she taxes the runner quite a bit. Like NAPD Contract she is a 2 point agenda with "5 to steal" except in archives. Instead of providing you agenda points she grants you a powerful ability which would be worth 6 advancements (see Mandatory Upgrades)
I think she is the strongest of all executives so far and is nicely balanced. Like all executives she suffers from Imp of recurring credits to trash, but on the plus side this "agenda" can not be scored with Film Critic!
