CORE DEFINITION

A more abstract graphical representation than a decision tree, used to show the interdependencies among decisions, uncertainties (chance variables), and objectives (value nodes).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Visualize causal chains. When doing complex strategic planning, drawing an influence diagram helps you clarify: what you can control (decisions), what you cannot control (environment), and how they jointly affect the final outcome.

An influence diagram is a more abstract graph than a decision tree, using decision nodes, chance (uncertainty) nodes, and value (objective) nodes with directed arcs to represent dependencies among variables, intuitively showing causality and information flow, facilitating structured complex decision-making.
