It is very difficult to understand a system without live it and analyze it. The simple system without comprehension is only a group of events with no meaning, that is why we need the analysis. It is imperative to observe the elements, their relationships and its purpose to find where are the leverage points. Those are areas of opportunity where a little change could trigger a massive change, where all parts involved in the system are comfortable with the situation. For example, companies measure its success by the profits, but how often they consider the environmental impact as part of the costs. 

The leverage points in our society lie in the perception of people, which are our parameters to consider success and the accomplishment of the main goals of a system.

The transition design is the main factor to discover those multi-level actions that will become on leverage points. Instead of simply deduction or making relations using the causality, the transition design guides the thinking process to analyze the problem and all its implications, in order to achieve a powerful solution.
