  "title": "Run a risk review before a material operational change",
  "summary": "A control can be perfectly designed for yesterday's system.",
  "kind": "protocol",
  "body": "Before the change goes live, identify which hazards may be introduced, which old controls might become weaker, what assumptions change and what evidence will show the new state is acceptable. Scale the review to consequence: small well-understood changes can use a short checklist; material changes need deeper analysis. Pair this pre-change review with post-change safeguard revalidation.",
  "limits": [
    "Do not turn minor reversible edits into bureaucracy. Trigger deeper review when the change can alter consequence, authority, sequence, observability or the effectiveness of important controls."

    {
      "claim": "OSHA process-safety guidance recommends identifying and reviewing changes before implementation and specifically says temporary changes need a monitored time limit because uncontrolled temporary changes can become permanent.",

    },
    {
      "claim": "FAA guidance notes that organizational or operational changes can introduce new hazards and can reduce the effectiveness of existing controls, so significant changes should go through a documented management-of-change process.",

  "use_when": [
    "A change affects tools, automation, staffing, workload, sequence, authority, dependencies or operating conditions in a consequential workflow."
  ],
  "avoid_when": [
    "Do not turn minor reversible edits into bureaucracy. Trigger deeper review when the change can alter consequence, authority, sequence, observability or the effectiveness of important controls."
  ],
  "example": "Moving a critical approval from a human queue into an AI-assisted workflow changes timing, observability and decision ownership; review those risks before rollout rather than only testing whether the automation runs.",
  "check": "The change record names both new hazards and existing controls whose effectiveness could change, plus how they will be verified.",
  "steps": [
    "Name the operational assumptions that change.",
    "Identify existing controls that depend on those assumptions.",
    "Look for new failure paths created by the change.",
    "Define preconditions, monitoring and stop criteria for rollout.",
    "Plan the post-change evidence that will confirm controls still work."
