Attempt to Determine Non-Fault Case through System Engineer Sensitivity during Each Software Design Process

Abstract

Even when a software is exclusively developed according to its design documents, User's may still perceive the actual software being different from what was documented on the design documents. In software development project, the deviation between System Engineer and user's perception of completed software is known as Non-fault case project. This Non-Fault Case is commonly due to User's misinterpretation of the software design document. Nonetheless, Non-Fault Case is only identifiable upon software completion. However, it has been reported that System Engineer may have early detection of User's misconception, which leads to Non-Fault Case. In this paper, we propose Bayesian classifier that predicts Non-Fault Case through System Engineer sensitivity during each software-design process. We have confirmed the process and data input method used for Bayesian classifier.
