Interpretive Structural Modeling (ISM) is a methodology for identifying relationships among all items, which define a problem or an issue. It is a computer-supported process that helps transform unclear and poorly articulated mental models of systems into visible Influence Maps
Applications of ISM
- Support small groups to develop graphical representations of complex systems. ISM was found to provide its users with a systematic and comprehensive method for integrating group judgments in the development of structural models.
- Reduce (i.e., optimize) the time required for assessing a relation between all factors in a set.
- Discover the root causes of a problem or an issue.
- Discover the factors that are more influential and provide the highest leverage to those wishing to change the state of a system.
