Meadows started with a nine-point list of such places, and expanded it to a list of twelve leverage points with explanations and examples, for systems in general. She describes a system as being in a certain state, consisting of a stock and flow, with inflows (amounts entering the system) and outflows (amounts leaving the system). At a given ...
High-leverage points, if any, are outliers with respect to the independent variables. That is, high-leverage points have no neighboring points in R p {\displaystyle \mathbb {R} ^{p}} space, where p {\displaystyle {p}} is the number of independent variables in a regression model.
By contrast, the key to successful intervention is identifying the leverage points where relatively minor alterations can effect a substantial change to a system's behavior. This section expands on an influential essay "Leverage Points - Places to intervene in a system" that Meadows originally published in Whole Earth in 1997. [10]
In case of a tie, point totals are added together and divided among all golfers tied for a particular position at the end of a tournament. For example, if four golfers finish tied for fifth place, the fifth through eighth place points are summed and divided by four, with each of the golfers receiving the same number of points.
When discussing how to optimize the system, it can be beneficial to discuss what a leverage point is. The leverage point in the system is a place where structural changes can lead to significant and lasting improvements to the system. There are two kinds of leverage points: [3] Low leverage point – These points are usually the places in the ...
A system archetype is a pattern of behavior of a system.Systems expressed by circles of causality have therefore similar structure.Identifying a system archetype and finding the leverage enables efficient changes in a system.
Closely related to leveraging, the ratio is also known as risk, gearing or leverage. The two components are often taken from the firm's balance sheet or statement of financial position (so-called book value ), but the ratio may also be calculated using market values for both, if the company's debt and equity are publicly traded , or using a ...
