安全预算与成本效益 · 概念解析 | Safety Budget & Cost-Benefit · Core Concepts

第 23 块 · Domain 2 · 项目管理 · 25%Block 23 · 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「安全预算与成本效益」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 Budget & Cost-Benefit 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「安全预算与成本效益」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 Budget & Cost-Benefit 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

    安全的钱要讲财务语言。事故成本是冰山：直接成本（医疗、赔偿、保险）只露 15–20%，间接成本（停工、换人再培训、设备损失、罚款、商誉、士气）常是它的 2–10 倍。投资论证用期望损失：概率 × 单次损失，与控制成本比回收期。预算分五桶：人员、检测设备、工程改造、培训、应急储备。优先排序按「风险削减额 ÷ 成本」的比值从高到低，先做性价比最高的。

    Safety money speaks finance. Incident cost is an iceberg: direct costs (medical, compensation, insurance) are the visible 15–20%; indirect costs (downtime, backfill and retraining, equipment, fines, reputation, morale) run 2–10 times. Justify investment with expected loss — probability times single-event loss — against control cost for payback. Budget in five buckets: staffing, instrumentation, engineering retrofits, training, emergency reserve. Rank by risk reduction per dollar and do the best ratio first.

    为什么先学它 / Why first
    D2 的预算题是「翻译题」：把风险翻成钱（期望损失、回收期），再把钱翻回风险（削减额）。考试给概率与损失让你算回收期，给四项措施让你按性价比排序——两个套路都要熟。
    Budget items in Domain 2 are translation items: risk into money (expected loss, payback) and money back into risk (reduction). The exam gives probability and loss for payback math, or four controls to rank by value — drill both patterns.
    它管到哪里为止 / Where it stops
    本块不覆盖财务会计准则与保费精算细节，不练习 FMEA 或 LOPA 的完整计算，只取其结论用于排序。
    This block skips accounting standards and premium actuarial detail, and full FMEA/LOPA math — only their conclusions for ranking.

    先认个脸 | Terms you will meet

    1. Direct Cost — 直接成本
    2. Indirect Cost — 间接成本
    3. Expected Loss — 期望损失
    4. ROI (Return on Investment) — 投资回报
    5. Risk Reduction — 风险削减
    6. Cost-Benefit — 成本效益

    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：考成本冰山的比例感：间接成本量级。
    Tests iceberg magnitude: indirect cost scale.

    一起手部割伤的直接成本是 2,000 元。按冰山比例，间接成本的合理量级是？

    A hand laceration carries 2,000 in direct costs. A reasonable order for the indirect costs is?

    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. 拿你们最近一起可记录事故，把直接与间接成本各列三项。
    Take your latest recordable; list three direct and three indirect costs.
