Data Precision Ranking数据精确度等级
Secondary Risk二次风险 Occurrence of one event is not related to occurrence of the other 一件事情的发生与其他事情的发生无关（期望值分析和决策数分析的必要条件）
Purpose is to test the value of data (input to Qualitative Analysis)数值测量（质量分析的输入）

(part of Risk Response Planning)（风险应对计划的一部分）
Path Convergence路径汇聚 Tendency of parallel paths of equal duration to delay the completion of the milestone where they meet所有在此处的延迟会导致汇合于此处的任何路径的延迟
Contingency Plan应急计划

Uncertainty不确定性 Planned action steps to be taken if an identified risk occurs. (e.g. developing alternative activity sequences)如果风险发生，应该采取计划措施的步骤（如：制定备选方案）
An uncommon state of nature, characterized by the absence of any information related to a desired outcome.一个偶然事件，对未来事件缺乏认知
Workaround权变措施 Unplanned response to negative risk events (requires to be impacted by the risk first)对不利的风险事件的未经计划的应对措施（首先要压缩风险）
Expected Monetary Value期望值 = Probability * Monetary Impact (used in Decision Tree Analysis)概率*得失量（用于决策树分析）
Risk Event风险事件 A discrete occurrence that may affect the project for better or worse. After a risk event, the project manager’s role is to reassess the risk ranking. The risk owner is responsible to take action when an identified risk occurs.可能导致项目变好或者变坏的不连续事件。风险事件过后，项目管理者的任务是重新评估风险等级。当风险发生时，风险所有者有责任采取行动
Risk Trigger风险触发器 A symptom of risk; indirect manifestation of actual risk event; output of risk identification; example is poor morale一种风险征兆；间接的表现出风险事件；风险鉴别的输出；
Risk Portfolio Risk data assembled for the management of the project项目管理中的风险数据组合
Utility Theory效用理论 Technique that characterizes an individual’s willingness to take risk描述个体承担风险意愿的方法
Sensitivity Analysis敏感性分析

Risk Auditor风险核对 

Risk Tolerance风险容忍度
 Places a value on the impact to the project plan by adjusting a single project variable; simplest form of analysis最简单最经济的定量分析方法（没考虑风险要素间关系及概率）
Role is to investigate the effectiveness of the risk owner (which can cause potential conflict with risk owner)
任务就是调查风险所有者可能的影响力（可能引起潜在风险的风险所有者）
Risk Taker, Risk Adverse, Risk Neutral; if you know the tolerance of the stakeholders, you can determine how they might react to different situation and risk events. You use this information to help assign levels of risk on each work package.风险承担者，风险转变者，风险中立者；如果你知道干系人的承受度，你就能判定他们在不同的情况和风险事件中在多大程度上给与反应。用这种方法帮助你确定每一个工作包中风险的等级
 
Responses to Risk风险应对措施 
Avoidance (elimination/abatement)规避（消除/排除） Eliminating cause eliminates risk. Can be done by changing the Project Plan or protecting project objectives from its impact.消除风险产生原因。通过修改项目计划来消除某些风险或使项目目标免受风险的影响（在项目早期风险可通过澄清要求获取信息，加强沟通，听专家的，来规避）
Mitigation (reduction)缓解（减轻） Reduce the Expected Monetary Value. Float can be use to mitigate potential risks设法将负面风险事件的概率或带来的不利后果减小到可接受范围内
Transfer转移 Deflect or share (eg. Insurance, warranties)转移或分担（保险，担保）
Acceptance接受 Accept or retain consequences. 2 types: Active Acceptance (develop a contingency plan) or Passive Acceptance (no action).接受或保留结果。2种形式：主动接受（开发一个应急计划）或被动接受（不采取任何行动）
Numbers to Know需要知道的数字 The range of an estimate with the smallest range is the least risky.估算的范围越小引发的风险越小
