Building Safety into the System Design

System Safety, as practiced by the U.S. defense and aerospace communities as well as the new approach outlined in this book, fit naturally within the general systems engineering process and the problem-solving approach that a system view provides. This problem-solving process entails several steps. First, a need or problem is specified in terms of objectives that the system must satisfy along with criteria that can 

The following are some examples of basic systems engineering activities and the role of safety within them  

Any specific realization of this general systems engineering process depends on the engineering models used for the system components and the desired system qualities. For safety, the models commonly used to understand why and how accidents occur have been based on events, particularly failure events, and the use of reliability engineering techniques to prevent them. Part II of this book further details the alternative systems approach to safety introduced in this chapter, while part 111 provides techniques to perform many of these safety and system engineering activities.
