How does a team conduct an effective software systems safety analysis for a small embedded system?

What is required to get safety board (SSSTRP and WSESRB) approval?

We were hired to develop training for a Navy engineering team to teach them just that. The training enabled them to examine Safety-Critical software code and it’s associated requirements, designs, etc. to determine the residual safety risk. The training was targeted towards a MIL-STD-882 safety program.

Aspects of the System Safety Assessment covered in the class included:

• System Overview and Operation
• Circuitry Overview
• Software High-Level Design
• Safety Features
• Hardware-Software Interface
• Risk Assessment Methods
• Detailed Software Safety Analysis
• Software Hazard Analysis (Failure Mode Considerations)
• Interruptibility Analysis (Race conditions, Deadlock, etc.)
• Stack Depth Analysis
• Microcontroller Errata
• Safety Risk Assessment
• Safety-Related Deficiencies and Recommendations
• Non-Safety-Related Deficiencies and Recommendations
• Recommended Tests
