systemtænkning

Systemtænkning, or systems thinking, is an approach to understanding complex problems by examining the relationships, structures, and dynamics that produce observed behavior, rather than focusing on individual components in isolation. It emphasizes holistic thinking, feedback processes, and the idea that the whole is more than the sum of its parts.

Central concepts include stocks and flows, feedback loops (positive and negative), delays, nonlinearity, and emergent properties that arise from interactions within a system. Tools commonly used are causal loop diagrams, stock-and-flow diagrams, and other modelling techniques that help reveal leverage points and potential unintended consequences.

The field has roots in general systems theory developed by Ludwig von Bertalanffy and in the systems dynamics tradition initiated by Jay Forrester. The approach was popularized in management and organizational contexts by Peter Senge’s The Fifth Discipline, which describes learning organizations, and by Donella Meadows and others in the late 20th century who advocated practical modelling for policy and sustainability.

Systems thinking is applied across domains, including business strategy, public policy, healthcare, ecology, and engineering. Practitioners use it to diagnose root causes, forecast the effects of interventions, design more robust processes, and foster adaptability. Methodological strands include hard systems approaches that construct formal models and soft systems methods that explore multiple perspectives and values, such as soft systems methodology.

Critiques note that models can oversimplify real-world complexity or be difficult to validate, and that success depends on stakeholder engagement and clear purpose. When used well, systems thinking supports better insight into leverage points, resilience, and long-term outcomes.
