Improving interpretive structural modelling for agile methodology using two-way assessment

In the 21st century, software engineering is focused on giving a quality product on time along with coping with the on-going market demand and its conditions. Hence, there is a technique of interpretive structural modelling (ISM) which is highly established in the field of research to mark interrelationships among different attributes. ISM uses a step by step technique to address the issue. Based on the relativity for comparison of variables and analysing criteria, structural self-interaction matrix (SSIM) is established. Reachability matrix (RM) is developed from (SSIM) and its transitivity are evaluated based on various attributes for their effective execution in the changing environment. Primarily, focus is on the ISM model in order to distinguish important features and then apply two-way assessment which considers the perspective of management along with testers and thus highlights the importance of various traits to measure the overall utility considering the threshold scenario in an organisation.
