A leverage point is a point in a system where a small intervention can have a big impact. Think of a small piece of plywood lifting a very large load of rocks, hundreds of times the weight of the wood doing the heavy lifting. The tricky bit is finding out where the key leverage points are. There are many examples of management decisions or interventions that have taken a lot of resources and energy but had seemingly no effect. Understanding where the leverage points are will make interventions more effective.

In 1999 researcher and author Donella Meadows wrote an article where she listed 12 possible leverage points.
