Growth And Underinvestment
The Growth and Underinvestment Archetype is one of the common system archetype patterns defined as part of the system dynamics discipline. System dynamics is an approach which strives to understand, describe and optimize nonlinear behaviors of complex systems over time, using tools such as feedback loops in order to find leverage pointof the system. As part of this discipline, several commonly found patterns of system behavior were found, named and described in detail. The Growth and Underinvestment Archetype is one of such patterns. Elements of Archetype The system described in the Growth and Underinvestment Archetype consists of three feedback loops. Each feedback loop can be one of two types: * Reinforcing loop – A reinforcing loop is a type of a feedback loop, where a positive increase of variable A causes an increase in variable B, which then in turn causes a positive increase in variable A. The behavior of such system in time is an exponential increase in both variables ...

System Archetype
System archetypes are patterns 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. The basic system archetypes and possible solutions of the problems are mentioned in the section '' Examples of system archetypes''. A fundamental property of nature is that no cause can affect the past. System archetypes do not imply that current causes affect past effects. Circles of causality The basic idea of system thinking is that every action triggers a reaction. In system dynamics this reaction is called feedback. There are two types of feedback – reinforcing feedback and balancing feedback. Sometimes a feedback (or a reaction) does not occur immediately – the process contains delays. Any system can be drawn as a diagram set up with circles of causality – including actions, feedbacks and delays. Reinforcing feedback (+) Reinforcin ...
