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
- Input to Control Quality
- Input to Control Communication
- Input to Control Risks
- Input to Control Procurements
- 输入控制利益相关方参与
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).
Work Performance Information
According to the PMBOK Guide, the Work Performance Information is “the performance data collected from various controlling processes, analyzed in context and integrated based on relationships across areas, e.g., the status of deliverables, forecasted estimates to complete, etc.”
Work Performance Information helps you analyze the Work Performance Data and compare the planned performance with the actual performance.
Examples of Work Performance Information
Work Performance Information includes, but is not limited to:
- 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,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,因此您可以预测您的进度并接受纠正措施if needed.
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.
理解这两个概念对于成功通过PMP考试至关重要。
你怎么收集性能数据的p工作吗rojects and prepare work performance information? Please share your experiences in the comments section.
Why Work Performance Report as an input leads to Work Performance
Information as an output in Monitor Communication? Discuss
This information is clearly mentioned in the PMBOK Guide. Please refer to it.
顺便说一下, it is work performance data is being converted to work performance information in monitor communications process.
PLEASE CAN I GET A COMPLETE DATA ON THE WORK PERFORMANE
I did not understand you.
Salam alikom brother Fahad,
I found your explanation is much better than what is available in YouTube.
thankyou for your great explanations
那nks Majed for your visit and leaving comment.
Hi Fahad,
Maybe I posted my situation in a wrong blogpost. I think this should be the right one.
I have one fundamental question about work performance information given as a input to “Monitor & Control” process.
If my understanding is correct, all the control processes compares the current data with the corresponding baselines, and raises change requests for any deviations. These change requests are sent to “Integrated Change Control” for further processing. However, the same information is provided as “Work Performance Information” to “Monitor & Control Project work” process. In this process also, the work performance information is compared with performance baselines. This as well gives raise to change requests
Isn’t this a duplicate effort? Can you be kind enough to differentiate between the objectives of control processes and “monitor & control project work” process?
你好维贾伊,
Please refer to the page 87 of the PMBOK Guide fifth edition. You will see that output of all controlling processes is work performance information and it is an input to monitoring and controlling project work process.
There is no repetition of effort.
嗨,Vejay,
my understanding to your question is WPIs sent as input to MCPW to issue a WPR only and that WPR will be input to PICC.BMBOK in not perfect and there are many circumstances either wrong or not well explained and thats why they updated it.
Very informative thank you.
You are welcome Dhanunjaya.
Hello Usman,
那nks for the explanation. A few things are still not clear, can you please explain
Risks – Work Performance Data
Here you will see how many identified and unidentified risks have occurred, how many new risks are identified, the effectiveness of risk response plan, how much contingency or management reserve has been utilized, the impact of risks on project constraints such as schedule, cost, and scope, etc.
What point is not clear to you?
Can you provide the Input / Output list of other terms like you mentioned in this page.
e.g:
Work performance data — Output to some and input to some processes
Work performance information — output to some and input to some processes
请提供与其他术语相同的模式。
那nks
I provide it whenever I can but can I not provide it in full as it will be copyright violation. I suggest you read the PMBOK to understand the ITTO.
hi talha,
WPD is output of DMPW
WPD is inputs to the 10 monitoring and controlling processes except for the two processes in the integration management ( MCPW,PICC) .
WPIs is outputs of the 10 monitoring and controlling processes except for the two processes in the integration management( MCPW,PICC) .
WPIs is input to MCPW.
那nks mate, very clear explanation!
You are welcome Qlitosucito.
感谢您的努力和感谢。此外,为了强调我所理解的内容,我想讨论以下案例: -
30% of the project is completed (WPD) and the actual cost incurred as of now is 150,000 US$ (WPD), which is let’ s say 15% more than the PV -Planned Value (WPD).
基于这些“原始”数据,项目经理提出了EAC(WPI),TCPI(WPI)等的预测。
Finally the project manager compiles all the above information and documents it to develop a Project Status Report (WPR).
Your comments are remarks are very much appreciated.
那nks again.
是的,你是对的哈桑。
One can see the trend that other than human resource management, WPD is almost always the input of control processes and WPI is almost always the output of those processes.
Human Resource management doesn’t have a process in Monitor & Control process group, so no question of inputs / outputs.
Well presented. Thanks.
You are welcome Ivan, and thanks for stopping by.
I am glad Atif that you find my blog useful.
Great hard work Fahad!
WPD和WPI使我感到困惑。现在,阅读您的博客后对我来说很明显。
One of my concern is to memorize the input, tool and technique and outputs. Your comprehensive analysis also lessen my poor “Ratta”(Ability to memorize) concern as well.
到目前为止,良好的工作……非常有帮助。请在工作授权系统中撰写博客,进行采购。
那nks
Malaka
Okay Malaka.
我已经注意到了您的要求,并将很快就这些观点撰写博客文章。
那nk you for taking the time to break down the concept so I can see why and when WPD is performed. When you look at input and output of each process you don’t see what is really happening. So now I can visualize that when they say raw data that generated by the iron triangle and works through the other processes to be an input into M/C Project works WPI to develop reports. When you read the PMBOK it’s hard to visualize the process as you are reading step by step processes and the project is more of a ” progressive elaboration” :)
Once again
谢谢
You are welcome Ralph.
Dear Fahad
在所有博客中,Crystal Clear的解释,您还可以提及博客标题中的最后更新吗?
thanks a lot for the clear cut explanations!
我尽量保持所有的帖子,和更新。
explained on a very good way
多谢
Very nicely explained, very easy to understand !
那nks,
Neil
I am glad that I could be of help.
谢谢你!
You are welcome Sandra.
This is very crisp and compact info about WPD and WPI.
那nks for compiling and sharing with all.
Best Regards,
Bhavesh Patel
I’m glad that I could help you.
Very well explained!!
那nks Rajat.
This was very comprehensive and provided a context for my learning on this section. Thank you.
不客气玛格丽特。
Your explanation helped me clear my concept until i read Page 251 of pmbok 5:
8.3.1.4工作绩效数据
在第4.3.3.2节中进行了描述。Work performance data can include:
Planned vs. actual technical performance,
Planned vs. actual schedule performance, and
Planned vs. actual cost performance.
And all my concepts are messed up again.
Please help.
Usman
P.S:
Confusion: A comparison between Planned vs. actual is supposed to make it a work performance information. e.g, SV, CV
Hello Usman,
我认为您已经在PMBOK指南中确定了差异(或可能我正在误解它)。bob手机客户端
However, if you go to point 4.3.3.2, it explains the correct concept.
那nks for your response.
为了信息共享,PMBOK第305页的第10.3.1.4节说:
10.3.1.4 Work Performance Data
在第4.3.3.2节中进行了描述。工作绩效数据组织并总结了收集的信息,并将比较分析的结果与绩效测量基线提出了结果。
谢谢…
My PMBOK (5th Edition) says: 10.3.1.4 Described in Section 4.3.3.2 Work performance data can include details about which communications have actually been distributed, feedback on communications, survey results on communication effectiveness, or other raw observations identified during communication activities.
I think this supports Fahad’s explaination and perhaps PMI simply did a poor job in updating the 5th edition. @Usman, Odd that your 5th edition and mine say totally different things.
谢谢…very useful ….I think you may need to modify the “Summary part” under Performance report as it still refers to old terms.
你好维贾伊,
感谢您指出的……
Assalaam walekum ,,,can u send to me cmplt data with formula of emplyess performance ..on this mail id[email protected]
请发送给我,我需要cauz对我来说非常重要。
