风险vs uncertainty

通常认为风险与该区域的不确定性相同风险管理。一种lthough there is a big difference between risk and uncertainty, many professionals often think they are the same.

尽管从PMP或PMI-RMP考试的角度来看,这个概念并不重要,但您必须理解差异以避免混合它们。

Therefore, I’m writing this blog post to explain it and I hope after reading it, you won’t have any problems distinguishing between risk and uncertainty.

风险

一种风险is an unplanned event that may affect one or some ofyour projectobjectives if it occurs. The risk is positive if it affects your project positively, and it is negative if it affects the project negatively.

负面的否定性和积极因素有单独的风险反应策略。

The objective of a负风险反应策略是为了最大程度地减少其影响或概率,而正风险反应策略是最大化机会或影响。

You might also hear two more risk terms: known and unknown. Known risks are identified during the identify risks process and unknown risks are those you couldn’t identify.

一种应急方案is made for known risks, and you will use the contingency reserve to manage them. On the other hand, unknown risks are managed through a解决方法using themanagement reserve

Uncertainty

不确定性是缺乏完全确定性。在不确定的情况下,任何事件的结果都是完全未知的,并且不能衡量或猜测。您没有有关活动的任何背景信息。

不确定性不是未知的风险。

In uncertainty, you completely lack the background information of an event, even though it has been identified. In the case of unknown risk, although you have the background information, you missed it during the identify risks process.

一种Real-World Example of Risk and Uncertainty

一种ssume two famous teams consist of renowned players, and they are going to play a football match the next day.

您能告诉我哪支球队将要赢得胜利?

不,你不能;但是,您可以通过审查和分析每个球员,团队以及他们相互对抗的比赛结果的过去表现来进行良好的猜测。

然后,您可以提出一些数字,例如A或B队赢得30%的机会,或者有70%的A或B团队输掉比赛的可能性。

现在,让我们在不同的情况下进行相同的足球比赛。

Let us say again that two teams are going to play a game, and no players are selected for either team.

在这种情况下,如果有人问您要赢得哪支球队,您的回应将是什么?

You will be clueless because you don’t know which team consists of which players, and you have no idea how the teams will perform.

在这里,即使规则和体育场是相同的,您也没有任何有关过去绩效的信息,也无法预测事件的结果。

这种情况称为不确定性。

风险Vs Uncertainty

以下是风险和不确定性之间的一些差异:

  • 在风险下,您可以预测未来结果的可能性,而在不确定性下,您不能。
  • 在不确定性无法控制的情况下,可以管理风险。
  • 可以测量和量化风险,而不确定性则不能。
  • 您可以为风险事件分配概率,而不确定性则不能。

Conclusion

风险和不确定性是不同的术语,但人们倾向于混淆它们。管理风险更容易,因为您可以根据自己的经验来识别它们并制定响应计划。但是,管理不确定性非常困难,因为以前的信息没有可用,涉及太多参数,并且您无法预测结果。

但是,要成功完成您的项目,您必须非常谨慎,积极主动且开放,以管理风险和不确定性。

这是风险与不确定性职位结束的地方。希望现在您可以将不确定性与风险区分开。仍然有一些疑问,在评论部分中发布它们,我会回复您。
