An evaluation of argument patterns to reduce pitfalls of applying assurance case

In this paper, we will introduce some of the problem areas that Japanese software engineers are susceptible to during the creation of assurance cases, based on the author´s educational experience with assurance cases. In addition, methods for dealing with these problem areas will also be explained. To mitigate these problems, it is expected to apply assurance case patterns that help engineers develop assurance cases by reusing those patterns. It is also shown an evaluation result of assurance case pattern application to develop an assurance case for a LAN device management system.
