事故调查与根因分析深化 · 概念解析 | Incident Investigation & RCA Deep Dive · Core Concepts

第 21 块 · Domain 2 · 项目管理 · 25%Block 21 · 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「事故调查与根因分析深化」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 Incident Investigation & RCA Deep Dive 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「事故调查与根因分析深化」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 Incident Investigation & RCA Deep Dive 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

    调查五步：封现场、收证据、建时间线、找根因、定纠正措施并跟踪。证据三类：人证（24 小时内访谈、记原话）、物证（拍照封存、维护证据链）、书证（记录、许可、监控）。根因在系统层面：五问法问到底、鱼骨图按人机料法环分类，都停在「人失误」就是没做完。纠正措施分级：消除>工程>管理，每条带负责人与验证日期——「加强教育」单独出现等于没查。

    Five steps: secure the scene, collect evidence, build the timeline, find root causes, assign corrective actions and track them. Evidence classes: testimonial (interview within 24 hours, verbatim notes), physical (photograph and preserve, maintain chain of custody), documentary (records, permits, video). Root causes live at the system level: five whys and the fishbone stop nowhere if they stop at 'human error'. Corrective-action tiers: elimination above engineering above administrative, each with an owner and a verification date — 'more training' alone is an unfinished investigation.

    为什么先学它 / Why first
    D2 的调查题考两个反直觉点：一是「人失误不是根因」（考题会把舒适答案摆在选项里），二是「惯例性违规是线索不是结论」（班长说『他平时也这么开』指向的是监督失守）。守住这两点，调查题不丢分。
    Investigation items test two counter-intuitive points: 'human error is never a root cause' (the comfortable answer sits in the options) and 'a routine violation is a clue, not a conclusion' (a supervisor's 'he always drives like that' points at supervisory gaps). Hold these two and investigation items hold their points.
    它管到哪里为止 / Where it stops
    本块不展开事故致因理论流派史（海因里希三角的沿革），不练习 bow-tie 与 barrier 分析的完整作图，OSHA 1904 记录口径已在块 2 讲过、此处不重复。
    This block skips accident-causation theory history and full bow-tie/barrier diagramming; OSHA 1904 recordkeeping was covered in block 2 and is not repeated.

    先认个脸 | Terms you will meet

    1. Root Cause Analysis (RCA) — 根因分析
    2. Five Whys — 五问法
    3. Fishbone Diagram — 鱼骨图
    4. Chain of Custody — 证据链
    5. Corrective Action — 纠正措施
    6. Timeline Reconstruction — 时间线重建

    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：考根因的定义边界：「人失误」为什么不是根因。
    Tests the boundary of root cause: why human error is not one.

    调查报告写道「根因：操作工注意力不集中」。这份报告的问题在于？

    A report states: root cause — the operator lost focus. What is wrong with this report?

    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. 翻一份你们最近的事故报告，检查根因写到了系统层还是个人层。
    Open your latest incident report; check whether the root cause sits at system or person level.
