  "summary": "Variation is expensive when it carries no useful information.",
  "kind": "principle",
  "body": "Standardize recurring control positions, terminology, states and routine sequence where differences do not serve the task. Preserve variation only where context genuinely requires it. Familiar consistency reduces training burden and slip risk when people move between similar processes.",

    "Do not standardize away domain-specific distinctions merely to make interfaces look uniform."

  "example": "Use the same status names and escalation semantics across several internal support workflows instead of local synonyms for identical states.",
