Analysis of “defect root cause and corrective actions” and its impact on “software system quality”

Abstract

Nature of software systems and its usage have changed significantly, so its complexity has grown exponentially. It is very difficult and challenging to maintain quality of software systems as user requirements and environment in which system is being used are constantly changing. If user requirements are not met, it is defined as defect. Defect must be analyzed, root caused and fixed to help improve software system quality. In this research study defects are analyzed based on root cause analysis, and different root cause categories and corresponding corrective actions are identified. This study analyses different attributes of defects which are interdependent with root cause & corrective actions and how they impact software system quality.
