Work Performance Data and Work Performance Information

At a glance, Work Performance Data and Work Performance Information seem similar; although they are closely related, these distinct terms will help you better understand and navigate your project’s status.

Work Performance Data gives you rough data on the project’s status and helps you create the Work Performance Information, the basis of绩效报告。

A performance report is an essential communication tool for a project manager, and to create this report; you will need both Work Performance Data and Work Performance Information.

In today’s blog post, we will discuss the merits of these two terms.

Work Performance Data and Work Performance Information

如果您了解这两个概念，则创建绩效报告并不困难。让我们从工作绩效数据开始。

Work Performance Data

根据PMBOK指南，工作绩效数据是bob手机客户端“在进行项目工作的活动期间确定的原始观察和测量值，例如实际成本，实际持续时间以及实际完成的工作百分比。”

工作绩效数据是项目参数的状态，例如完成了多少工作，已经过去了多少时间以及到目前为止所产生的成本。

Examples of Work Performance Data

工作绩效数据包括但不限于：

• Scope:You will see the requirement, non-conformities, the number of change requests received versus those accepted or rejected, etc.
• 时间：您将看到已经开始了多少个活动，完成了多少工作，当前正在进行的活动的状态等。
• 成本：您会注意到该项目的成本绩效：完成了多少工作，迄今为止花了多少钱，等等。
• 质量：You will measure the technical performance, such as the characteristics of the product, quality metrics, number of defects, and the rejection rate.
• 通讯：您将看到已分发了哪些报告，这些通信报告的反馈等。
• Risks:您将看到发生了多少确定和未知风险，确定了多少个新风险，风险响应计划的有效性，多少contingency or management reservehas been utilized, and the impact on project constraints such as schedule, cost, and scope.
• Procurement:在这里，您将获得有关与采购有关的活动：卖方，卖方的绩效等符合质量标准等。

接下来，让我们在PMBOK指南中查看WPD：bob手机客户端

• 直接和管理项目工作的输出
• 验证范围的输入
• 控制范围的输入
• 输入到控制时间表
• Input to Control Cost
• 控制质量的输入
• Input to Control Communication
• Input to Control Risks
• 控制采购的输入
• Input to Control Stakeholder Engagement

WPD是一个直接的输出和管理项目的工作。It is gathered throughout the execution phase and then sent to various controlling processes for further analysis: Validate Scope, Control Scope, Control Schedule, Control Cost, etc.

从这些数据中，您可以创建工作绩效信息（WPI）。

工作绩效信息

根据《 PMBOK指南》，工作绩效bob手机客户端信息是“从各种控制过程中收集的绩效数据，在上下文中分析并基于跨领域的关系进行集成，例如可交付成果的状态，预测的估计值，等等。”

工作绩效信息helps you analyze the Work Performance Data and compare the planned performance with the actual performance.

工作绩效信息的示例

工作绩效信息包括但不限于：

• Scope:You will review the project’s progress: e.g., the status of deliverables, whether the deliverable is accepted, how the project scope is performing against thescope baseline， ETC。
• 时间：You will compare the planned schedule with the actual schedule. You can see the planned duration of an activity, and the time taken by the activity to be completed, etc.
• 成本：You can see the planned cost for a task and compare it with the actual cost, i.e., the planned cost versus the actual cost spent. You will also review other parameters, such as cost variance and cost performance.
• 质量：You will analyze the planned technical performance versus actual technical performance: how many defects, how much tolerance and threshold were allowed, how much it costs, and how much rework is required.
• Risk:You will compare how manyidentified risks发生了，风险响应计划的效率，已经花费了多少应急资金，应急或管理储备的余额等。
• Procurement:Here, you will review the seller’s performance.

让我们看一下PMBOK指南，该指南将WPI描述为：bob手机客户端

• 输入以监视和控制项目工作
• 验证范围的输出
• 控制范围的输出
• 控制时间表的输出
• The output of the Control Costs
• 控制质量的输出
• The output of the Control Communications
• 控制风险的输出
• 控制采购的输出
• 控制利益相关者参与的输出

You can see that the Work Performance Information is an output of various controlling processes and is an input to Monitor and Control Project Work, where it is used to generate the performance reports.

工作绩效数据与工作绩效信息。

• 工作绩效数据显示了项目的当前状态。工作绩效信息是实际绩效与计划绩效之间的比较。
• 工作绩效数据的示例是实际花费的成本，经过的实际时间等。工作绩效信息的示例是成本差异，进度差异，成本绩效指数，时间表绩效指数等。

WPD and WPI show you where the project is going, so you can forecast your progress and take corrective action if needed.

Summary

工作绩效数据是您项目观察结果的原始数据，工作绩效信息是实际数据和计划数据之间的分析和比较。这两个是您的绩效报告和基本交流工具的骨干，可以帮助您监视项目的进度并将其与计划的进度进行比较。

理解这两个概念对于成功通过PMP考试至关重要。
