uncertain pedigree (SOUP) in
No full textThis report considers the use of `software of uncertain pedigree' (SOUP) in safety-related applications. In the proposed approach, the safety assurance of SOUP is based on a documented, five-phase safety justification (or safety case) that sets out the safety claims for the system, and the evidence and arguments that support them.
