Current Issues in Safety-Critical Systems contains the invited papers presented at the eleventh annual Safety-critical Systems Symposium, held in February 2003. The safety-critical systems domain is rapidly expanding and its industrial problems are always candidates for academic research. It embraces almost all industry sectors; current issues in one are commonly appropriate to others. The Safety-critical System Symposium provides an annual forum for discussing such issues. The papers contained within this volume cover a broad range of subjects. They represent a great deal of industrial experience as well as some academic research. All the papers are linked by addressing current issues in safety-critical systems: Dependability Requirements Engineering; Human Error Management; Influences on Risk; Safety Cases; Reforming the Law; Safety Management and Safety Standards.
