Propose a Method of Requirements Review Considering Adverse Conditions.

In a product development project, it may lead to extra costs if defects caused by the requirement definition process are discovered during the post-process. Therefore, it is important to find defects in requirements by considering details not described. However, there is no inspection method established for adequately grasping the boundary conditions of the review target and considering the range that is not described in the requirements specifications, and it depends largely on the experience and skills of reviewers. To solve this problem, we propose an analytical framework to organize the boundary conditions of the review target and propose a review method that considers adverse conditions which are beyond the boundary range. We confirmed the applicability of the method with case studies and organized the analytical framework to derive adverse conditions based on the results.
