This notification is to announce the update to wording within COTS, MOTS, and Modified COTS and MOTS within 4. How to Do It [1].

Additional wording has been added to aid the decisions made around the complexity of producing a Safety Case. Wording has been updated to state that for a simple PSS a Safety Case may not be required, with the intent of reducing the activity involved with, and burden of, excessive amounts of Safety Cases, particularly where a Safety Case would add no great value.
