• DO-178B is the primary set of guidelines employed by the aerospace industry to create safe and robust software.

• DO-178B describes processes to be followed in the software development and verification lifecycle.

• There are five levels of safety impact assessments – A,B,C,D,E; Level A is the most rigorous.

Some of the processes in DO-178B include:

• Requirements-based software development
• Requirements-based software verification
• Independent peer review of software products
• Independent peer review of test cases and test procedures
• Robustness and out of range testing
• Structural coverage analysis
• 100% traceability from requirements to testing
