Systems Thinking is a holistic analysis approach that focuses on the way that a system's basic parts interrelate and how systems work over time and within the context of larger systems. It is a framework based on the premise that the way to fully understand why a problem occurs and persists is to understand the "part" in relation to the "whole." Engineers seeking to achieve systems thinking are expected to understand the linkages and interactions among the elements of their system or enterprise and its connecting entities. The benefits of systems thinking as opposed to scientific reduction is that it maximises the outcomes achieved and minimizes the impact of unintended consequences while managing uncertainty, risk and opportunity. (Source: Wikipedia)
