工作绩效数据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.

工作绩效数据为您提供了有关项目状态的粗略数据，并帮助您创建工作绩效信息，performance reports.

绩效报告是项目经理的必不可少的通信工具，并创建此报告。您将需要工作绩效数据和工作绩效信息。

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

工作绩效数据and Work Performance Information

If you understand these two concepts, creating performance reports won’t be difficult. Let’s start with Work Performance Data.

工作绩效数据

According to the PMBOK Guide, Work Performance Data is “the raw observations and measurements identified during activities performed to carry out the project work, e.g., actual cost, actual duration, and the percent of work physically completed.”

工作绩效数据is the status of project parameters, such as how much work has been completed, how much time has elapsed, and the cost incurred so far.

Examples of Work Performance Data

工作绩效数据includes, but is not limited to:

• Scope:You will see the requirement, non-conformities, the number of change requests received versus those accepted or rejected, etc.
• Time:You will see how many activities have been started, how many finished, the status of current ongoing activities, etc.
• Cost:You will note the project’s cost performance: how much work has been completed, how much money has been spent to date, etc.
• 质量:您将衡量技术性能，例如产品的特征，质量指标，缺陷数量和排斥率。
• Communications:You will see which reports have been distributed, the feedback on these communication reports, etc.
• 风险：You will see how many identified and unidentified risks have occurred, how many new ones are identified, the effectiveness of the risk response plans, how much应急或管理储备has been utilized, and the impact on project constraints such as schedule, cost, and scope.
• Procurement:在这里，您将获得有关procurement-related activities: quality standards met by the seller, the seller’s performance, etc.

Next, let’s review WPD in the PMBOK Guide:

• The output of Direct and Manage Project Work
• Input to Validate Scope
• Input to Control Scope
• Input to Control Schedule
• Input to Control Cost
• 控制质量的输入
• Input to Control Communication
• Input to Control Risks
• Input to Control Procurements
• Input to Control Stakeholder Engagement

WPD is an output of Direct and Manage Project Work. 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.

From this data, you can create the Work Performance Information (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.

Examples of Work Performance Information

工作绩效信息包括但不限于：

• Scope:您将审查项目的进度：范围基线, etc.
• Time:您将将计划时间表与实际时间表进行比较。您可以看到计划的活动持续时间以及要完成的活动的时间，等等。
• Cost: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:您将分析计划的技术绩效与实际技术绩效：允许多少缺陷，容忍度和阈值，成本多少以及需要多少返工。
• Risk:您将比较多少确定的风险have occurred, the efficiency of the risk response plan, how much of the contingency money has been spent, the balance of the contingency or management reserve, etc.
• Procurement:Here, you will review the seller’s performance.

Let’s have a look at the PMBOK Guide, which describes WPI as:

• Input to Monitor and Control Project Work
• The output of the Validate Scope
• 控制范围的输出
• The output of the Control Schedule
• 控制成本的输出
• The output of the Control Quality
• 控制通信的输出
• The output of the Control Risks
• The output of the Control Procurements
• The output of the Control Stakeholder Engagement

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vs Work Performance Information.

• 工作绩效数据shows the current state of the project. Work Performance Information is a comparison between the actual performance with planned performance.
• Examples of Work Performance Data are the actual cost spent, the actual time elapsed, etc. Examples of Work Performance Information are Cost Variance, Schedule Variance, Cost Performance Index, Schedule Performance Index, etc.

WPD和WPI向您展示该项目的去向，因此您可以预测进度并在需要时采取纠正措施。

Summary

工作绩效数据is the raw data from observations of your project, and Work Performance Information is the analysis and comparison between the actual data and the planned data. These two are the backbone of your performance reports and essential communication tools, helping you monitor the project’s progress and compare it with the planned progress.

Comprehending both concepts is essential to pass the PMP exam successfully.
