There are quite a few IT governance frameworks like TOGAF 9 Architecture Governance that references Control Objectives for Information and Related Technology (COBIT). However in my point of view they are quite theoretical as well.
If you had a look at the Building blocks of an IT architecture roadmap instead you would realize that the IT architecture execution building block is what IT governance really is about:
- IT architecture execution happens within the projects that implement the IT initiatives defined in the IT architecture timeline building block, i.e. this is IT governance in practice rather than in theory.
- During IT architecture execution building block IT architects ensure that the IT architecture principles are understood and applied as well as the IT architecture patterns. These are practical examples of the clear policy development and good practice for IT control recommended by COBIT.
- Most important however is the IT architecture exception process that allows for deviations from the IT architecture principles and IT architecture patterns and thereby indicates necessary improvements of the IT architecture roadmap. It is this continuous improvement that lets IT governance gain credibility in an organization to the point where its value is widely recognized and therefore its adoption welcomed rather than resisted.
So in essence, if you had an IT architecture roadmap and executed it you would not have to worry about IT governance because you would just be doing it already!
