Version Control for Safety Cases

Branch, Diff & Merge

Explore a plant modification, a design option, or an assessor's challenge in an independent copy of the live safety case — then compare it against the original and merge only when it is agreed.

An Independent Copy, Not Another Spreadsheet

Create a branch from any project in one click: a fully editable, fully isolated copy with its own audit chain. Engineers can work up a modification, a what-if for a decommissioning phase, or the response to a regulator's query without touching the approved case — no v7_FINAL_revB workbooks, nothing emailed around, and the approved case is never left in an intermediate state.

See Exactly What Changed

Always compared against today's approved case, not the copy you started from. Someone else edits it, another branch merges in — you'll see that too. Faults added or removed, barriers rescoped, claims strengthened or weakened, evidence attached, consequences and sub-systems revised — a change set a review board can read in a meeting, not a spreadsheet compare.

Merge When Agreed, With the Trail Intact

Fast-forward merge the branch into the approved case once the change is accepted. The merge is itself a recorded audit event, so the formal case shows exactly what was brought in, by whom and when — and the branch's own history is preserved rather than flattened into the parent.

Built for Real Change Control

Pair it with SAFOPS's Change Impact Analysis: test a modification before it is raised, branch to work it up, compare it for the review, merge on approval. Every step is deterministic and every step is on the record.
