Risk Assessment
Risk assessment turns vague worry into prioritized actions: what can go wrong, how bad, what we do now, and who owns follow-up.
When to Offer This Workflow
Trigger conditions:
- - Major launch, migration, or new vendor
- Steering or audit requests a risk matrix
- Post–near-miss prevention work
Initial offer:
Use six stages: (1) scope & stakeholders, (2) identify risks, (3) analyze likelihood & impact, (4) plan mitigations, (5) owners & deadlines, (6) review & tracking). Confirm scoring approach (simple matrix vs quantitative).
Stage 1: Scope & Stakeholders
Goal: Define system/project boundary and who can accept residual risk (product, eng, legal).
Exit condition: RACI or explicit approvers for go/no-go.
Stage 2: Identify Risks
Goal: Brainstorm across categories: technical, security, operational, legal, reputational, financial.
Practices
- - Pre-mortem: “It failed because…” exercise for alignment
Stage 3: Analyze
Goal: Score likelihood and impact with a shared rubric; avoid false precision.
Stage 4: Plan Mitigations
Goal: Prevent, detect, and respond controls; rough cost/time per mitigation.
Stage 5: Owners & Deadlines
Goal: Each material risk has an owner and date; escalation path if unmitigated by launch.
Stage 6: Review & Tracking
Goal: Living RAID log; revisit after scope changes or incidents.
Final Review Checklist
- - [ ] Scope and decision authority clear
- [ ] Risks span relevant categories
- [ ] Scoring applied consistently
- [ ] Mitigations have owners and dates
- [ ] Residual risk explicitly accepted or deferred with plan
Tips for Effective Guidance
- - Distinguish future risk from current defects.
- For security-heavy systems, align with threat (threat modeling) outputs.
- Startups: fewer rows, more honesty on top existential risks.
Handling Deviations
- - Regulated industries: follow required RA templates when mandated.
风险评估
风险评估将模糊的担忧转化为优先行动:可能出现什么问题、有多严重、我们现在该做什么、谁负责跟进。
何时提供此工作流程
触发条件:
- - 重大发布、迁移或新供应商
- 指导委员会或审计要求提供风险矩阵
- 事后预防工作(针对未遂事件)
初始提议:
使用六个阶段:(1) 范围与利益相关方,(2) 识别风险,(3) 分析可能性与影响,(4) 规划缓解措施,(5) 负责人与截止日期,(6) 审查与跟踪。确认评分方法(简单矩阵 vs 定量分析)。
阶段 1:范围与利益相关方
目标: 界定系统/项目边界,确定谁能接受剩余风险(产品、工程、法务)。
退出条件: RACI 或明确的审批人,用于决定是否继续推进。
阶段 2:识别风险
目标: 跨类别进行头脑风暴:技术、安全、运营、法律、声誉、财务。
实践方法
- - 事前剖析:“它失败是因为……”练习,用于达成共识
阶段 3:分析
目标: 使用共享评分标准对可能性和影响进行评分;避免虚假精确。
阶段 4:规划缓解措施
目标: 预防、检测和响应控制措施;每项缓解措施的粗略成本/时间。
阶段 5:负责人与截止日期
目标: 每项重大风险都有负责人和日期;若在发布前未缓解,则明确升级路径。
阶段 6:审查与跟踪
目标: 维护动态 RAID 日志;在范围变更或事件发生后重新审视。
最终审查清单
- - [ ] 范围和决策权限明确
- [ ] 风险涵盖相关类别
- [ ] 评分应用一致
- [ ] 缓解措施有负责人和日期
- [ ] 剩余风险已明确接受或附有计划延期处理
有效指导技巧
- - 区分未来风险与当前缺陷。
- 对于安全密集型系统,与威胁(威胁建模)输出保持一致。
- 初创公司:减少行数,对顶层生存风险保持更多诚实。
偏差处理
- - 受监管行业:在强制要求时,遵循规定的风险评估模板。
