质量控制vs Verify Scope

质量控制vs Verify Scope

在第五版的PMbob手机客户端BOK指南中,验证范围流程取代了验证范围过程。因此,这篇文章已过时。请参阅我的新博客文章质量控制和验证范围

The quality control and verify scope processes are important for a project as they ensure that the deliverable is defect free and meets the user’s requirements.

由于这两个过程都涉及检查和测试,许多专业人员都会感到困惑,并认为他们是一样的。他们有不同的目标,并以不同的目标牢记。

质量控制

在质量控制过程中,您可以检查可交付的正确性,并查看其是否符合规格。

团队成员在整个监控和控制阶段进行质量控制活动。这样可以确保产品无缺陷,并且所有参数都在可接受的限制范围内。

There are many tools and techniques to use during this process, including: inspection,因果图,,,,控制图,运行图表,,,,scatter diagram, ETC。

Example

现在,让我们看看控制质量过程的真实示例。

您被任命为政府建造1,000公里道路的政府合同的项目经理。在您的团队中,您有一位质量控制工程师来监视质量活动。

该质量控制工程师将在现场进行检查,并建议如果需要,则建议对可交付的更改,以使其符合既定的要求。他将检查所提供的所有材料是否具有所需的质量,例如煤焦油,石头被正确压碎,地面是正确的,或者人行道是否正确对齐,等等,等等。

验证范围

在此过程中,您将与客户一起检查可交付的可交付方式,以查看它是否满足所有要求并且可以接受。

验证范围过程是在项目的监视和控制阶段进行的。

这两个过程都只有一个相似性:它们是在项目的监视和控制阶段进行的。但是,验证范围流程的目的是获得客户对可交付的正式接受。

Example

Now we will look at the verify scope activities using the same example discussed above.

您已经建造了100公里所需的1,000公里的道路,并可以发货。您邀请当局来检查并正式接受。

政府代表到达并验证您是否符合所有要求。他们检查了一些标准,例如,如果道路宽度正确,道路升级还可以,并且是道路已完成的部分的长度。

Once they are satisfied, they will formally accept the completed part of the road and you get paid.

Please note that it is not always necessary to perform the verify scope process at the end of every project. It can happen far before the project ends. You can also perform the verify scope activities with the quality control process, as is seen in the example above.

In the given example, both processes are being performed in parallel. The government’s representatives are verifying the scope for the completed part of the road with you, and at the same time, your team is building and testing the rest of the road.

Differences Between Quality Control and Verify Scope

质量控制和验证范围过程之间的差异如下:

  • 质量控制涉及产品的质量,而验证范围流程涉及产品范围。
  • Quality control activities are performed internally, while the verify scope process is performed with the client.
  • 质量控制活动是在项目执行过程中执行的,而验证范围过程通常是在项目或阶段结束时执行的。
  • The objective of the quality control process is to produce a defect-free product, while the purpose of the verify scope process is to get the deliverable accepted by the client.

结论

Both the control quality and verify scope processes are important for a project. The quality control process helps to create a defect-free and high-quality product. The verify scope process helps to get the product accepted by the client. Quality control activities are performed throughout the monitoring and controlling phase and verify scope activities are needed when the deliverable is ready to be delivered.

还有另一个称为质量保证的过程,通常被误认为是质量控制。请拜访:质量保证和质量控制了解更多有关它的信息。

  • 嗨,法哈德,

    Thank you for your useful post and simple explanations. I’ve noticed a contradiction on your post.

    Under the “Verify Scope” headline of your post, you stated that “The verify scope process is also performed during the monitoring and controlling phase of the project.

    这两个过程均在项目的监视和控制阶段进行,但是,这是唯一的相似性。”

    Under the “Conclusion” headline, on the other hand, you stated that “Quality control activities are performed throughout the execution phase”

    附注:根据RITA的过程图表质量控制,在监视和控制阶段进行。

    • Executing and Monitoring phases occur simultaneously. You are working on a deliverable and at the same time you are monitoring it as well so as to make it defect free.

      • 嗨,法哈德,

        How do you answer the following questions? (I’m just trying to fill my knowledge gap. I only study from Rita’s book, and maybe this is a wrong strategy for me.)

        Q1: In which process group you perform quality control?

        a)计划
        b)执行
        c) Monitoring&Controlling
        d) Closing

        问题2:您在哪个过程组中执行质量保证?

        a)计划
        b)执行
        c) Monitoring&Controlling
        d) Closing

  • 嗨,法哈德,我喜欢关于道路建设的类比,非常好。

    I wonder if by including in your example QA aspects of the project, will aid explanation of the 3 very closely related aspects of QA/QC? Of course this have been mentioned already; i did not read all the messages! regards Gordon

  • 嗨,法哈德。
    I am quite confuse of the Verified deliverable as output of Control Quality and input of Verify scope. Some of the trial exams and even PMBOK 5th edition, it is Validated deliverable in Control Quality output. Hope you can help me with this confusion.

  • 我认为此博客文章有一个错误。当您尝试解释质量控制与验证范围之间的区别时,我认为您是要说“质量控制与验证范围”。验证来自拉丁“ Veritus”的意思。当您验证某些内容时,您会评估产品,服务或系统是否符合法规,需求,规范或强加条件。这是一个内部过程。结果,您说要在帖子上进行验证和质量控制是同一件事。
    您所说的以验证您的帖子验证是为了“验证”而不是验证。
    验证某事意味着保证产品,服务或系统满足客户或确定的利益相关者的需求。它通常涉及接受或补充。它是外部的,是在PM和利益相关者之间进行的。

  • Hi – I’m studying for the pump exam. Can you please confirm if the correct name is verify scope. Pmbok 5 references this process as validate scope.

    谢谢!! I just want to make sure I get the terminology correct. ????

  • Hi
    我发现了这个论坛,发现它很有趣。有没有皇家皇家印版的国王和ITIL非常好的解释,这使得事情现在很清楚
    为我

    • 感谢卡尔文的访问。

      我没有在RMP上看到任何博客,但是您可以在许多PMP论坛和博客上找到许多相关的RMP讨论和注释。bob官网竞彩足球

      对Itil不知道。

  • 嗨,法哈德 -

    当我准备六月中旬的考试时,您能尽快解释一下。另外,您是否有关于diff的任何博客文章。优质的扭动(Juran,Deming等)?我也对差异感到困惑。项目选择方法。

    太感谢了

  • 嗨,法哈德,

    非常感谢您的博客和您的解释,您能帮我了解如何计算标准偏差吗?我似乎没有明白。

    谢谢

    • 你好桑格塔,

      要计算标准偏差,您必须计算平均值和方差。然后,只有您才能计算标准偏差。

      无论如何,现在我将写一篇博客文章,涵盖这些观点。发布此帖子后,希望您在计算标准偏差时永远不会有任何问题。

  • I also like Andy Crowe’s explanation of the two processes

    Verify scope refers to the completeness and Quality control refers to the correctness

  • 法哈德,
    我正在准备PMP考试。
    我刚刚碰巧看到您的博客。
    The subtle difference between various quality terms are nicely explained.
    多谢。
    Mani Naga

  • 谢谢。因此,从解释中可以得出结论,质量控制和验证范围实际上仅是表现剂不同的?也就是说,客户所说的质量控制是在表演组织的眼睛/嘴唇中验证范围
