第 22 块 · Domain 2 · 项目管理 · 25%Block 22 · Domain 2 · Program Management · 25%第 1 / 5 课 · 概念解析Lesson 1 of 5 · Core Concepts

本课只做一件事：搞清「安全绩效指标体系」到底是什么、为什么考试要先过这一关、它管到哪里为止。

Get clear on what Safety Performance Indicators really is, why it comes first, and where it stops.

本课不涉及：不展开细节与题目——那是第 2–5 课的事。
Not covered here: No detail, no questions — those are lessons 2 to 5.

本课目标 | Learning objectives

  1. 能用一句话说清「安全绩效指标体系」解决的是什么问题
  2. 能举出一个「不懂它就一定做错」的例子
  3. 知道本课的边界，不把后续课的内容提前混进来

  • State in one sentence the problem Safety Performance Indicators solves
  • Give one example where missing it guarantees a wrong answer
  • Know this lesson's boundary and keep later lessons out

    它是什么 | What it is

    指标分两族：滞后指标（TRIR、DART、LTIR——事后结果）与领先指标（检查完成率、整改及时率、观察数、未遂报告——事前动作）。成熟体系两族配对使用：滞后告诉你「结果如何」，领先告诉你「结果将如何」。两个率共用同一副公式骨架：病例数 × 200,000 ÷ 总工时，区别在分子口径——TRIR 数可记录病例，DART 数损失工时病例。指标最大的敌人是被操纵：只报好消息、降低分级、少报未遂，要用交叉验证拆穿。

    Indicators come in two families: lagging (TRIR, DART, LTIR — outcomes) and leading (inspection closure, corrective timeliness, observations, near-miss reports — actions). Mature systems pair them: lagging tells how you did, leading tells how you will do. Both rates share one skeleton: cases × 200,000 ÷ hours; the difference is the numerator — TRIR counts recordable cases, DART counts days-away cases. The enemy is gaming: selective reporting, downgraded classification, suppressed near misses — cross-validation exposes it.

    为什么先学它 / Why first
    D2 的指标题考三件事：算（×200,000 骨架别记错）、配（领先滞后怎么搭）、识破（哪个信号说明数字被操纵）。第三件最反直觉——「TRIR 大降 + 未遂报告暴跌」不是成绩，是警报。
    Domain 2 indicator items test three things: compute (the ×200,000 skeleton), pair (leading with lagging), and detect (which signal betrays gaming). The third is the least intuitive — 'TRIR plunges while near-miss reports collapse' is an alarm, not an achievement.
    它管到哪里为止 / Where it stops
    本块不覆盖 1904 记录判定的逐条细节（已在块 2 讲过），不展开统计过程控制与趋势检验的数学。
    This block defers 1904 recordability detail (covered in block 2) and the mathematics of trend testing.

    先认个脸 | Terms you will meet

    1. TRIR (Total Recordable Incident Rate) — 总可记录事故率
    2. DART (Days Away, Restricted, or Transferred) — 损失工时事故率
    3. Leading Indicator — 领先指标
    4. Lagging Indicator — 滞后指标
    5. Severity Rate — 严重率
    6. Benchmark — 基准对标

    这里只要求认得；定义、易混与例句在本块第 3 课「术语精讲」。/ Recognition only — definitions come in the glossary lesson of this block.

    情景自测 | Scenario check

    本课理解Lesson comprehension

    这道题考什么：考两族指标的分工：谁看结果、谁看动作。
    Tests the division of labor: outcomes versus actions.

    把「月度安全检查完成率」归入哪一族？

    Which family does 'monthly inspection completion rate' belong to?

    自编练习题，不是 BCSP 官方真题，也不能用来预测分数。 / Original practice item, not an official BCSP exam question.

    动手练 | Practice

    1. 列出你公司月报里的全部指标，逐个标注领先/滞后。
    List every metric in your monthly report; tag each leading or lagging.
