  "summary": "Architecture boxes tell you what exists. Function links tell you what the boxes are doing to each other.",
  "kind": "protocol",
  "body": "For the relevant components, write subject–function–object links: component A does function F to component B. Mark each interaction as useful, harmful, insufficient or excessive for the current objective. This exposes unnecessary actors, weak functions and harmful interactions that a component inventory hides.",
  "limits": [
    "Function labels are analytical judgments; verify harmful or insufficient interactions with evidence before redesigning the system."

      "claim": "The TRIZ Body of Knowledge includes function analysis and trimming as system-analysis methods, and the 2025 systematic review identifies both among tools used in process-improvement work.",

  "use_when": [
    "A system diagram shows components but does not explain why each component exists or how it helps or harms another."

  "avoid_when": [
    "Function labels are analytical judgments; verify harmful or insufficient interactions with evidence before redesigning the system."
  ],
  "example": "A validation job checks records before import (useful) but also serializes all processing through one worker (possibly excessive constraint).",
