Safety Critical Software Development 

Safety-critical typically means where a failure could mean the loss of life, significant property damage, or environmental damage. Delivering Software in this area is both difficult and expensive; for example, meeting a SIL 4 safety standard equates to < 1 failure per a billion hours of continuous operation.

In many domains, software developers are focused on shipping software as fast as possible, updating features as the inevitable bugs pop out and then repeating this cycle, providing end users with additional value as the product matures. 

For safety critical systems this approach is not possible, software engineers must create systems that are safe and meet all regulatory compliances above all else. For this reason, safety-critical software development is typically a very specialised and process-driven field of software development, but which creates the most dependable software out there. 

Safety-critical software systems are often embedded, distributed systems and must consider the interactions with other devices and networks. For example, the rapid growth in IoT can create further complexities when devices are now connected to other systems that are using software or protocols that have not been developed under the same rigour with respect to safety or compliance. 

It’s difficult and can be expensive to create safety-critical software and there are no magic bullets to deliver these solutions; it comes down to Process, Experience and Expertise.
