no I cannot give you a road map. Roadmap assumes that I know the road. So how do I know the road? I know the road because I've seen it in the past. So that means I'm assuming the past will essentially be similar in the future as well. If the future is a little bit different than the past, my past knowledge is not going to be very useful. I cannot have a roadmap. So to hope for a roadmap, to hope for a best practices is in illusion, we must abandon to deal with complex problems. Is that making sense? This is very important because we need to make a distinction between these three class of problems. Your first job would be to essentially decide which one is simple, which one is complicated, which is complex. And then you cannot use the tool, those will be applicable for simple system when the problem is actually complex or vice versa. So, to assume that everybody's working on very complex problems. Each of the cases you heard about the beginning that people describe, they're all complex. They may have simple components within them, but basically the conflicts and what's at the heart of the conflicts are complex. It sounds from your description like it's not really possible to be usefully prescriptive in a situation in which the problems you're dealing with are highly complex. Do you think that's right or? No, I think no, that we're in trouble. At some level it is, but at some level it is not. So let me see what I can explain. So the story that what has to happen then is when you are confronted with a problem like
