  "title": "Keep priority pressure separate from feasibility evidence",
  "summary": "Importance can buy resources or scope changes; it cannot repeal dependencies.",
  "kind": "principle",
  "body": "When priority rises, first recompute the feasible options: add capacity where work is parallelizable, remove scope, shorten approval paths, accept explicit risk or move other commitments. Do not simply shrink the estimate because the task became important.",
  "limits": [
    "Throwing more people at tightly coupled or unfamiliar work can increase coordination cost; added capacity is not automatically added throughput."

    {
      "claim": "The 2026 Green Book recommends explicitly accounting for optimism bias in cost, benefit and duration estimates and using historical forecast errors from similar proposals where available.",

      "role": "supports",
      "note": "The guidance is for UK public appraisal; the transferable principle is empirical correction, not a universal percentage uplift.",

  "use_when": [
    "A high-priority request is assumed to require less time."

  "avoid_when": [
    "Throwing more people at tightly coupled or unfamiliar work can increase coordination cost; added capacity is not automatically added throughput."
  ],
  "example": "A Monday deadline is met by splitting validation and dropping a nonessential report, not by changing 'five days' to 'two' in the spreadsheet.",
