Intervention Level Framework

The Intervention Level Framework (ILF) is a tool designed for considering interventions within complex systems. This framework, based on Donella Meadows places to intervene in complex systems, collapses the twelve levels into five:

Paradigm: The most profound level, targeting fundamental beliefs and values that underpin the system. Changing paradigms involves shifting the core assumptions and ideologies that define system goals and approaches.

Goals: Focuses on the objectives and outcomes that the system aims to achieve. Modifying goals means altering what the system prioritizes, which can redirect efforts and resources towards new endpoints.

System Structure: Encompasses the network of relationships and interactions between the system's components. Intervening at this level means changing how parts of the system interact or are organized, potentially improving efficiency or effectiveness.

Feedback and Delays: Targets the mechanisms that regulate system behavior, including the feedback loops that amplify or dampen changes. Intervening here can adjust the system's responsiveness and adaptability.

Structural Elements: The most tangible level, involving changes to the physical, technological, and organizational components of the system. This can include introducing new technologies or modifying infrastructure.
