*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
*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.

Identification of variables Identification of the elements that are
relevant to the problem or issue
ISM- Raj Kabade
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

Identification of variables
Establish contextual
relationships between variables
Develop Structural Self
Interaction Matrix (SSIM)It indicates a pair-wise relationship
between sources

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.

ISM may be used on its own when the elements of
the issue are already known. Where this is not the
case, Nominal Group Technique may be introduced
as one step in the ISM process to assist the
participants in generating and clarifying the
elements to be structured
