Last year I started to dive into the theory behind complexity thinking. What puzzled me ever since is the relationship between complexity thinking and the stuff that I learned from Jerry Weinberg. One sleepless night I stood up from bed, and searched my material from the PSL course. There I learned about a model that helps me leading people in different ways. While thinking over it, it occurred to me, that complexity thinking is a small subset of the MOI(J) model. Follow me on my mind-journey.
