I have a small question: Can I convert my mission and vision with Cobit to IT-Goals? The aim is to use this processes in TOGAF for set up my Enterprise architecture, and using ITIL for evaluate, monitor and problem-solving of my processes?
Is this a good interpretation of the IT-governance frameworks? Or have I made a mistake?
No, your approach is spot on (also what I do in my daily job). I use ITIL for the processes involved in shaping the organization and processes, Cobit (I personally prefer the 4.1 version) to help prioritize what needs to be done (btw. there are matching tables in Cobit 4.1 linking it to ITILv3), to give you and idea on the relevant controls. I also think it's quite charming to have the CMMI section in Cobit giving you an idea on the right maturity.
