Program Plan Intro
Safety Critical System:
Safety-Critical System is the system where the system operations performed is always safe. The system does not provide any damage to the people or the other environment which is regardless to the specification it carries. Example of safety-critical system comprises of control process in chemical and pharmaceutical industries, control and monitoring system in aircraft.
There are two classes of safety-critical software. They are:
- Primary safety-critical software
- Secondary safety-critical software
