Our political decision-making systems, national and international, have developed over centuries. Sometimes – as with the many COP meetings – they operate extremely slowly. Sometimes with economic decisions they move dangerously fast. One difficulty is the sheer complexity and uncertainty of situations. But, says Prof. Iain Alasdair MacLeod, the discipline of system planning is standard practice for such situations, and is widely used. So could system planning also be used for political decision-making? And if so, how? Former Scottish Education Minister Peter Peacock chairs and welcomes questions and discussion.
