The document discusses the Interactive Structuring Method (ISM), which helps to identify relationships between elements of a complex system and structure them in a hierarchical model. It outlines the steps of ISM, including identifying variables, determining their contextual relationships, developing a structural self-interaction matrix (SSIM) and reachability matrix, and partitioning the matrices into levels. An example of applying ISM to identify the relationships between factors influencing an event is provided. ISM transforms unclear mental models into clear hierarchical models.

- 2. * *ISM is one of the Interactive Management methods which assist research groups in dealing with complex issues. *It is a well known methodology for identifying and summarizing relationships among specific elements, which define an issue or a problem, and provide a means by which order can be imposed on the complexity of such elements ISM- Raj Kabade
- 3. *It helps to identify structure within a system of related elements and provide the opportunity to analyze it from several viewpoints *ISM transforms unclear, poorly articulated mental models of a system into visible well defined, hierarchal models. ISM- Raj Kabade
- 5. Identification of variables Identification of the elements that are relevant to the problem or issue ISM- Raj Kabade
- 6. Identification of variables Establish contextual relationships between variables From the elements identified in the first step, establishing the contextual relationship among them - It represents which element leads or follows ISM- Raj Kabade
- 7. Identification of variables Establish contextual relationships between variables Develop Structural Self Interaction Matrix (SSIM) It indicates a pair-wise relationship between sources ISM- Raj Kabade
- 8. Identification of variables Establish contextual relationships between variables Develop Structural Self Interaction Matrix (SSIM) Develop a reachability matrix The SSIM format is transformed in the format of the reachability matrix by transforming the information in each entry of the SSIM into ‘1s’ and ‘0s’ in the reachability matrix.
