Thanks Paul – you are of course right in the linearity issue – I was thinking that the arrows around the outside of the diagram shouldn’t be arrows?
I think an outer ring of Systems and Infrastructure, people, and wider context and environment would help.
Regards number 3, again, yes, maybe describing some sort of Network? That Supports, Learning and Teaching change- maybe each of these lens would be better situated within a network of hexagons – that are interlinked 😉
