Adaptive practice on software reliability based on IEEE Std. 1633 in frequent requirement modifications

Abstract

This paper investigates an adaptive practice on software reliability in frequent requirement modifications. According to the conventional software development processes, software requirements are specified and locked at the early stage of software life cycle. As a project progresses, the requirements can be added and modified to reflect customers needs. However, it can be an obstacle to activities for software reliability engineered process if they are changed frequently. Software is developed in accordance with the requirements. If the frequency of software requirement modifications is high, the software is liable to be error-prone. It also makes the software reliability estimation activities reconfigurable. Therefore, we propose an adaptive approach to estimate software reliability which is based on IEEE Std. 1633.We show why the adaptive approach is necessary when software requirements are changed frequently through a case study. © 2010 Springer-Verlag Berlin Heidelberg.
