Ivan, According to your profile you work at SoftServe who implements RUP, something called Quality Management System (QMS) and as ISO certified - so you should have testing process defined already and it have to comply with the mentioned methodologies.
Could you tell us more about your mission? I have ever believed that vision provides your image of the (bright) future, not a copy-paste from manuals. To better establish that image I suggest you to read "Lessons Learned in Software Testing" by Cem Kaner, James Bach, Bret Pettichord.
One more comment - nowadays main challenges I know of are: how much will you relay on developer's unit tests, how much on capture-playback test automation tools, how much on scripted manual testing (copy-paste requirements and use-cases) and how much on Exploratory (tester skills-based) testing.
Also - do you need to do performance, reliability or security testing.
