There are three interdependent factors that drive our development processes: interval, quality and cost. As market pressures continue to demand new features ever more rapidly, the challenge is to meet those demands while increasing, or at least not sacrificing, quality. One advantage of defect prevention as an upstream quality improvement practice is the(More)
This paper describes a success story in large-scale global systems & software development. Carried out at several company locations and associated supplier sites, we describe how we manage and develop a complex embedded product in a global dynamic environment. Main acting locations are at Germany and China. Organizational key success factors include(More)
A plethora of defect prediction models has been proposed and empirically evaluated, often using standard classification performance measures. In this paper, we explore defect prediction models for a large, multi-release software system from the telecommunications domain. A history of roughly 3 years is analyzed to extract process and static code metrics(More)
The importance of software metrics gathered by measuring artefacts emerging during the software development process for economic and scientific purposes is beyond controversy these days. To help estimate project characteristics, measure project progress and performance or quantify product attributes, and thus to benefit from it in the long run, a suitable(More)
The ArQuE project has developed an integrated and comprehensive method that enables goal-oriented,architecture-centric development and strategic quality engineering. The consolidated expertise from applying the ArQuE approach at different industry partners shows the applicability and scalability in the embedded systems domain. The approach leads to reduced(More)
