EN 50716:2023 - Railway Applications - Requirements for Software Development A.11: Table A.11: data preparation techniques (8.4)

Table A.11 grades nine data preparation techniques: functional testing (Table A.13) M at every level; tabular specification methods and domain specific language R throughout; simulation R at Basic Integrity and HR above; checklists R at Basic Integrity, HR at SIL 1 and 2 and M at SIL 3 and 4; Fagan inspection R at SIL 1 to 4; formal design reviews R at Basic Integrity and HR above; formal proof that the data are correct HR at SIL 3 and 4 only; walkthrough R to SIL 2 and HR at SIL 3 and 4. Approved combinations: SIL 1 and 2, tabular specification with functional testing; SIL 3 and 4, tabular specification, functional testing, checklists and formal design reviews, or domain specific language, simulation, functional testing, checklists and Fagan inspection.
