This paper reports on our experience of investigating the role of software systems in the power blackout that affected parts of the United States and Canada on 14 August 2003. Based on a detailed study of the official report on the blackout, our investigation has aimed to bring out requirements engineering lessons that can inform development practices for dependable software systems. Since the causes...
A key challenge for software engineering is to learn how to reconcile the formal world of the machine and its software with the non-formal real world. In this paper, we discuss elements of problem oriented software engineering (POSE), an approach that brings both non- formal and formal aspects of software development together in a single theoretical framework for software engineering design. POSE...
Program verification assumes a formal program specification. In software-intensive systems, such specifications must depend on formalization of the natural, nonformal problem world. This formalization is inevitably imperfect, and poses major difficulties of structure and reasoning. Appropriate verification tools can help address these difficulties and improve system reliability
