The B-P-R model
My professional practice draws heavily on the principles of systems thinking, but exactly what this means is often not clearly understood. It is sometimes easier to explain what systems thinking means by first describing what it is distinct from.
Most analytical thinking that we do is based on a reductionist scientific paradigm, where we break down a large or complicated situation into its constituent parts and then analyse each of these in isolation. So, for example, this is the principle of a root cause analysis, where we identify separate root causes and find solutions for each of these.
