Recently, assurance cases standardized by ISO have received a lot of attention from researchers. A previous study showed that it is appropriate to use assurance case to demonstrate the improved feasibility of accomplishing management vision and management strategy using four models (Management vision model, Management strategy model, Business process model, and IT system model). However, in the previous study, concrete description methods were not discussed.
Filling this gap of knowledge, this study aims to show a detailed four-layered assurance case description method using D-Case approach to connect multiple layers of the hierarchical structure of an assurance case. This is an improvement from the previous in that it now focuses on one layer for improving the feasibility of accomplishing both management vision and management strategy. As a result, this study contributes to the existing literature by adding a description method for a four-layered assurance case that includes 30 steps and uses D-Case. This study concludes with future research topics.
