Work Performance Information (WPI) vs Work Performance Measurements (WPM)

这篇文章是基于第四编辑ion of the PMBOK Guide, and from the 5th edition of the PMBOK Guide, the PMI has changed the definitions of terms used in this blog post; therefore, this post is now obsolete.

我根据PMBOK指南的版本重新编写了此博客文章。manbet最新版请拜访Work Performance Data and Work Performance Information。I am leaving this post in case someone wants to review the old post under the PMBOK Guide (4^thedition).

管理人员始终对项目的状态和进度感兴趣。他们想知道：

• What percentage of the project is completed?
• What percentage is yet to be completed?
• How much money has been spent?
• 你赚了什么？
• 您是领先还是落后？

那么，您将如何为他们提供此信息？

您可以通过work performance report。This report shows all the information required byproject stakeholders, as defined in the communication management plan.

To prepare this report, you will need work performance information and work performance measurements.

Work Performance Information

工作绩效信息是项目状态的原始数据。它指的是工作的百分比已经完成，经过了多少时间，产生的成本等等。

It provides us with the current status of theproject。您可以使用此信息来创建工作绩效测量，然后创建工作绩效报告。

A few examples of work performance information are as follows:

• How much of the work has been completed?
• 是什么schedule’s progress?
• What cost has been incurred to date?
• What are the quality metrics of the product?
• 什么是风险状况？
• 是什么procurementperformance?

Work Performance Measurements

一旦获得状态，就可以将其与计划的进度进行比较，并提出工作绩效测量。它们是计划的进度与项目当前状态之间的比较。

Some examples of work performance measurements include:

Schedule Performance

Here you will compare the planned schedule with the actual schedule.

For example, for an activity that was scheduled to be completed in five days, work performance measurements show how long it actually took to complete.

成本性能

Here you will compare your planned expenditure with the actual expense.

例如，该活动的计划成本是多少，您实际花了多少才能完成？

质量Performance

Here you compare the planned performance with the actual performance.

For example, you will measure how many defects, tolerance, and threshold were allowed and how many occurred.

Risk Performance

在这里，您将看到您的有效性风险管理计划。

例如，您将看到发生了多少风险，与确定的风险，风险响应计划的有效性等等。

Procurement Performance

在这里你将比较卖方的实际性能nce against the planned performance.

The Difference Between Work Performance Information and Work Performance Measurements

The difference between work performance information and work performance measurements is as follows:

• Work performance information is the ‘as of now’ status of the deliverables, while work performance measurements are a comparison between the actual status and planned status.
• Work performance measurements are developed with the help of work performance information.
• 工作绩效信息的示例包括经过的时间和花费的钱，而成本差异和时间表差异，成本绩效指数和计划绩效指数以及更多是工作绩效衡量的示例。

Summary

Work performance information and work performance measurements help in赚取价值管理和预测。它们可以帮助您准备可以发送给利益相关者的绩效报告。基于此绩效报告，管理层决定如何进一步进行。

I hope you now have a better understanding of work performance information and work performance measurements.

Now you can move on to the next blog post, on theperformance report。
