Information–action ratio

The Information-Action Ratio (IAR) is a concept used to evaluate the efficiency of information in prompting action or decision-making. It highlights the balance between the amount of information acquired and the actions taken as a result of that information. The ratio can be expressed as: \[ \text{IAR} = \frac{\text{Information}}{\text{Action}} \] Where: - **Information** refers to the relevant data or insights that inform a decision or action.
