What is it?
The application of rigorous methods and analyses to the software that controls hardware hazards. It typically requires application of system engineering, software engineering, and safety engineering principles, and brings the different engineering disciplines together to focus on how software affects the safety of the system. Software System Safety defines the safety requirements for software developers and assures the implementation and compliance with those requirements.
APT’s Software System Safety Process
A proven software safety program, this process is successfully applied to major DoD programs. APT supports customers with AMCOM Regulation 385-17 compliance and presentation to the Software System Safety Technical Review Panel (SSSTRP) for software fielding approval. This process includes the following steps:
- Safety Program Initiation, System Assessment, Safety Planning
- Identify System Hazards, Identify Software Functions (or Safety-Significant Software Functions)
- Execute the SwSS Program, Mitigate Software Hazard Causes
- Monitor Test, Verification & Validation
- Support Software/ Materiel Release, Assess Hazard Risk, Track Risks to Acceptance
