Systemic thinking is a simple thinking technique for gaining systemic insights into life and complex situations and problems. If you want different outcomes from a situation, you have to change the system that underpins the situation in such a way that it delivers different outputs. In other words, you have to deal with things systemically. You can’t deal with the parts of a situation in isolation; you have to deal with them in concert. You have to deal with both the elements of a situation and how they interact with one another.
