12.3 Safety engineering processes
The software processes used to develop safety-critical software are based on the processes used in software reliability engineering. In general, a great deal of care is taken in developing a complete, and often very detailed, system specification. The design and implementation of the system usual follow a plan-based, waterfall model, with reviews and checks at each stage in the process. Fault avoidance and fault detection are the drivers of the process. For some types of system, such as aircraft systems, fault-tolerant architectures, as I discussed in Chapter 11, may be used.
Reliability is a prerequisite for safety-critical systems. Because of the very high costs and potentially tragic consequences of system ...
