Components of System Safety contains the invited papers presented at the tenth annual Safety-critical Systems Symposium, held in Southampton, February 2002. The papers included in this volume are representative of modern safety thinking, the questions that arise from it, and the investigations that result. They are all aimed at the transfer of technology, experience, and lessons to and within industry, and they offer a broad range of views. Not only do they show what has been done and what could be done, but they also lead the reader to speculate on ways in which safety might be improved.
