-This is pretty straight forward stuff. Nothing especially technical. We are concerned with the big picture related how systems integrate into organisations and how people use them. I used the standards from the IB<ref>http://www.ibo.org/</ref>, but added some other topics I think fit into this category (but not included by the IB).
