Improvement of Software Reliability Estimation Accuracy with Consideration of Failure Removal Effort

In order to develop highly reliable software in a cost-effective manner, it is necessary to manage software reliability at the early test phases. Most of developers at those phases perform a test and debug activities together. In this paper, we propose a new reliability estimation model to manage the reliability of individual units from the early test phases as a solution for considering the test and debug time together. Via the proposed model using experiment of actual data, we can improve the accuracy of software reliability estimation.
