Planning for Safety
Two decades of development have been directed toward establishing and evaluating the safety of complex systems. A special methodology and several methods of safety evaluation have been generally adopted by safety engineers in several fields, from aerospace to education. These methods depend on statistical inference, either in an informal and intuitive context (called good engineering judgment), or on a rigorous mathematical level. In recent years the advancement of the techniques of analysis and verification of safety has slowed, and considerable thought is going into determining the meaning and value to society of statistical measures of safety.
