Thinking Systemically - what is it and how might diagramming help?

In this session, I wish to explore 3 themes (1) the nature of 'thinking systemically' (2) the role of critical reflection in thinking systemically (3) the interplay between use of diagramming, critical reflection and thinking systemically.
The approach will be a mix of presentation and participant discussion. I will present some of my own thoughts on each theme, and at intervals ask participants to consider this input and discuss their views on the theme.
