Abstract
Assurance cases standardized by ISO have come to draw a lot of attention. With the aim of identifying challenges of assurance case description method in Japanese organizations, this study evaluates assurance cases created by beginners.

Second, we aim to confirm for which of visualizing strengths and visualizing weaknesses of the contents described in assurance cases work better. With this in mind, assurance case instructors could suggest the participants which of strengths and weaknesses they are likely to visualize in creating assurance cases. It will also help beginners create assurance cases. Third, this study aims to demonstrate the number of trainees who made mistakes in the test after the training with a view to disclosing the proportion of trainees who created assurance cases correctly after the training.
