Software defect prediction in automotive and telecom domain: A life-cycle approach

Abstract

Embedded software is playing an ever increasing role in providing functionality and user experience. At the same time, size and complexity of this software is also increasing which bring new challenges for ensuring quality and dependability. For developing high quality software with superior dependability characteristics requires an effective software development process with greater control. Methods of software defect predictions can help optimize the software verification and validation activities by providing useful information for test resource allocation and release planning decisions. We review the software development and testing process for two large companies from the automotive and telecom domain and map different defect prediction methods and their applicability to their lifecycle phases. Based on the overview and current trends we also identify possible directions for software defect prediction techniques and application in these domains.
