A root cause analysis format is a structured case record that connects a defined problem to evidence, tested causes, corrective actions, and measured follow-up. A useful RCA report contains the incident and impact, scope, team, evidence and timeline, candidate causes, analysis method, verified root cause and contributing factors, containment, permanent actions, owners, deadlines, effectiveness measures, approvals, and review dates.
根因分析报告格式是一份结构化案件记录，把明确定义的问题与证据、经检验的原因、纠正措施和量化复核连接起来。一份可用的 RCA 报告应包含事件与影响、范围、团队、证据与时间线、候选原因、分析方法、已验证根因与促成因素、临时遏制、永久措施、负责人、期限、成效指标、审批人与复核日期。
The format is not the analysis itself. A polished template cannot compensate for incomplete evidence, a blame-oriented team, or an untested causal claim. Its job is to make omissions visible, preserve the reasoning trail, and carry the investigation through action and verification.
格式本身不等于分析。再精美的模板也无法弥补证据不完整、团队倾向归责或因果主张未经检验的问题。格式的作用是暴露遗漏、保留推理轨迹，并让调查真正进入行动与验证阶段。
Prepare the inputs before filling the RCA template填写 RCA 模板前准备输入材料
Do not begin by writing a root cause. Begin by freezing the known facts and defining the decision. Preserve raw records where possible, document transformations, and separate observed facts from recollection, inference, and hypothesis.
不要一开始就填写“根因”。应先冻结已知事实并定义需要作出的决策。尽可能保留原始记录，记录所有处理步骤，并把观察事实与回忆、推断和假设分开。
- Case boundary: affected product, service, process, location, time window, population, and explicit exclusions.案件边界：受影响的产品、服务、流程、地点、时间窗、人群和明确排除项。
- Impact and priority: actual harm, exposure, downtime, quantity, cost range, compliance significance, and potential severity. Mark estimates as estimates.影响与优先级：实际损害、暴露范围、停机时间、数量、成本区间、合规意义与潜在严重性。估算值必须明确标记。
- Evidence pack: source records, timestamps, measurements, logs, photos, change history, procedures, interviews, samples, and chain-of-custody needs.证据包：来源记录、时间戳、测量、日志、照片、变更历史、程序文件、访谈、样本及证据保管要求。
- Team and authority: investigation lead, process owner, people who do the work, subject experts, data owner, action approver, and independent reviewer when risk warrants one.团队与权限：调查负责人、流程负责人、实际执行人员、领域专家、数据负责人、行动审批人，以及风险需要时的独立复核者。
- Stop conditions: legal hold, safety escalation, privacy restriction, evidence contamination risk, or conditions that require a specialist investigation.停止条件：法律保全、安全升级、隐私限制、证据污染风险，或必须转交专业调查的条件。

Example: a completed RCA report for delayed data refreshes示例：数据刷新延迟的完整 RCA 报告
Hypothetical example — not a customer case or product benchmark假设示例——不是客户案例或产品性能基准
Problem statement: During four scheduled runs in a two-week example period, a reporting dataset completed 42–67 minutes after its 06:00 target. Three downstream reports missed their internal delivery window. The investigation covers the orchestration and source-extraction path; it excludes report rendering after the dataset becomes available.
问题陈述：在一个为期两周的假设周期内，某报告数据集有四次计划运行比 06:00 目标晚 42 至 67 分钟完成，导致三份下游报告错过内部交付窗口。调查涵盖编排和源数据提取路径，不包含数据可用后的报告渲染。
Evidence and timeline: Scheduler logs show each delayed run entered a retry loop after a source connection was reset. Change records show the source team reduced an idle-connection limit before the first event. Comparable jobs that open a fresh connection per partition were unaffected. The team also finds that the extraction job treated the reset as retryable but retained an expired connection object.
证据与时间线：调度日志显示，每次延迟运行都在源连接重置后进入重试循环。变更记录显示，源系统团队在首次事件前缩短了空闲连接限制。每个分区都新建连接的可比作业未受影响。团队还发现，提取作业把连接重置视为可重试，却继续保留已经失效的连接对象。
Candidate tests: Traffic volume, data size, network loss, scheduler capacity, source connection policy, and retry handling are compared. Volume and data size are normal; other jobs share scheduler capacity without delay; packet-loss evidence is absent. In a controlled test, the old idle limit reproduces the loop only when the expired object is reused. Refreshing the connection breaks the loop.
候选检验：团队比较流量、数据量、网络丢包、调度容量、源连接策略与重试处理。流量和数据量正常，共享调度容量的其他作业没有延迟，也没有丢包证据。在受控测试中，只有重复使用失效对象时，旧的空闲限制才会复现循环；刷新连接后循环消失。
Cause statement: A retry path reused an invalid source connection after reset, while the reduced idle limit increased exposure to that path. The implementation defect is the controllable root cause; the policy change is a contributing trigger, not sufficient by itself.
原因陈述：重试路径在连接重置后重复使用无效的源连接，而缩短空闲限制提高了触发该路径的机会。实现缺陷是可控制的根因；策略变更是促发因素，但自身并不足以造成事件。
Actions and verification: Immediate containment restores the prior limit. Permanent action recreates connections on reset, adds a bounded retry and alert, and introduces a test for expired connections. The example effectiveness plan monitors 30 scheduled runs, requires zero unbounded retry loops, records completion latency, and triggers rollback and review if the loop reappears. These numbers are illustrative, not a recommendation for every system.
行动与验证：立即遏制恢复原限制。永久措施包括在重置后重建连接、增加有上限的重试与告警，并加入失效连接测试。假设成效计划监控 30 次计划运行，要求无无限重试循环，记录完成延迟；若循环再次出现，则触发回退与复核。这些数字仅用于说明，不是对所有系统的建议。
Validate the cause, action, and result separately分别验证原因、行动与结果
A credible RCA format contains three different tests. Mixing them produces false closure.
Does the cause explain the event boundary, timing, mechanism, affected and unaffected cases, and available evidence? What alternative explanation was rejected, and why?
该原因能否解释事件边界、时间、机制、受影响与未受影响案例及现有证据？哪些替代解释被排除，为什么？
Was the approved action completed as specified? Preserve configuration, test, inspection, training, purchase, or release evidence—not just a checked box.
批准的行动是否按要求完成？应保留配置、测试、检查、培训、采购或发布证据，而不只是勾选框。
Did the targeted failure mode, exposure, or consequence decrease over a meaningful period without creating unacceptable new risk?
目标故障模式、暴露或后果是否在有意义的周期内下降，且没有产生不可接受的新风险？
Did ownership, monitoring, documentation, maintenance, and change control become part of normal work after the project team dispersed?
项目团队解散后，所有权、监控、文档、维护和变更控制是否进入日常工作？
The CMS Five Whys worksheet offers a useful cause check: ask whether removing the proposed root cause would have prevented the event or problem. Treat that as a disciplined challenge question, not a substitute for evidence. High-risk cases may require more rigorous methods, independent review, or regulatory procedures.
CMS Five Whys 工作表提供了一个有用的原因检查：若移除所提出的根因，事件或问题是否能够避免？应把它作为严谨的挑战问题，而不是证据的替代品。高风险案件可能需要更严格的方法、独立复核或监管程序。
Common RCA report mistakes and limitations常见 RCA 报告错误与局限
- Writing the suspected cause into the problem statement. It anchors the investigation and makes contrary evidence easier to dismiss.把怀疑原因写进问题陈述。这会形成锚定效应，使反向证据更容易被忽视。
- Calling human error the root cause. Record the action, then examine tools, workload, incentives, procedures, training design, supervision, interfaces, safeguards, and why the error reached the outcome.把人为错误当作根因。应记录具体行为，并继续检查工具、工作量、激励、程序、培训设计、监督、界面、防护以及错误为何能造成结果。
- Using a diagram as proof. Fishbone branches and why-chains organize reasoning; they do not validate a causal mechanism. Attach tests, sources, and rejected alternatives.把图表当成证明。鱼骨分支和追问链用于组织推理，并不能验证因果机制。必须附上检验、来源和被排除的替代项。
- Choosing actions before the cause is tested. A familiar solution can pull the analysis toward a convenient explanation.在原因得到检验前选择行动。熟悉的解决方案可能把分析拉向方便的解释。
- Confusing completion with effectiveness. Publishing a procedure or delivering training proves an activity happened, not that recurrence risk changed.混淆完成与有效。发布程序或完成培训只能证明活动发生过，不能证明复发风险已经改变。
- Deleting uncertainty. Note missing evidence, disputed interpretations, assumptions, residual risk, and what would trigger reopening the case.删除不确定性。应记录缺失证据、有争议的解释、假设、剩余风险和重新打开案件的触发条件。
Limit: a general report format is not a replacement for sector-specific reporting, legal advice, safety investigation, medical review, forensic handling, or regulated CAPA requirements. Preserve mandatory fields and escalation rules from the governing process.
局限：通用报告格式不能替代行业特定报告、法律意见、安全调查、医学复核、取证处理或受监管的 CAPA 要求。必须保留适用治理流程规定的必填字段和升级规则。

What is the standard root cause analysis format?标准的根因分析格式是什么？
A practical RCA report records the problem and impact, scope, evidence and timeline, candidate causes, analysis method, verified root cause and contributing factors, containment, corrective actions, owners and due dates, verification measures, approvals, and follow-up.
实用的 RCA 报告记录问题与影响、范围、证据与时间线、候选原因、分析方法、已验证根因与促成因素、遏制、纠正措施、负责人和期限、验证指标、审批及后续跟踪。
Is a root cause analysis format the same as a 5 Whys template?根因分析格式与 5 Whys 模板相同吗？
No. A 5 Whys worksheet is one analysis method. A complete RCA format is the case record around the method: it also preserves evidence, scope, decisions, actions, ownership, verification, and follow-up.
不同。5 Whys 工作表是一种分析方法；完整 RCA 格式是围绕方法的案件记录，还要保存证据、范围、决策、行动、所有权、验证与后续跟踪。
How do you validate a root cause in an RCA report?如何在 RCA 报告中验证根因？
Check that the cause explains the evidence and timing, is specific and controllable, survives alternative explanations, and would have prevented or materially reduced the event if removed. Record the evidence and uncertainty instead of treating consensus as proof.
检查原因是否解释证据与时间、是否具体且可控制、能否经受替代解释，以及移除后是否能避免事件或显著降低其概率。应记录证据与不确定性，不要把共识当成证明。
What should a corrective action table include?纠正措施表应包含什么？
Include the action, linked cause, action type, owner, due date, required resources, completion evidence, effectiveness measure, review date, status, residual risk, and approver. Separate immediate containment from permanent corrective action.
应包含行动、关联原因、行动类型、负责人、期限、所需资源、完成证据、成效指标、复核日期、状态、剩余风险和审批人，并把立即遏制与永久纠正措施分开。
Can AI complete a root cause analysis report automatically?AI 能自动完成根因分析报告吗？
AI can help organize records, compare timelines, summarize evidence, and surface candidate relationships, but it does not prove causality by itself. Qualified owners must verify evidence, test alternatives, approve actions, and monitor effectiveness.
AI 可以帮助整理记录、比较时间线、总结证据并发现候选关系，但自身不能证明因果。合格负责人仍须验证证据、检验替代解释、批准行动并监控成效。
