Work Performance Data and (WPD) Work Performance Information (WPI)

Collected data within a project is always in the raw format. Information is the processed, analyzed and integrated form of raw data and the reports are created to adress stakeholder’s needs. In project management, Work Performance Data and Work Performance Information are two tools that are widely used for project monitoring. Although both of them help to recognize the project’s current status, they are different. Work Performance Data is raw observations and measurements about the project’s current status. The Work Performance Information compares the actual and planned values. Both terms are closely related to each other and they help to understand the project’s current status. In this article we will analyze both terms by the help of examples.

Work Performance Data (WPD)



Primary function of a project manager is to complete the project on time and budget by meeting the stakeholder‘s requirements. For this purpose, the project manager collects data related to project activities such as start date of an activity, project risks, consumptions, resource usage etc.

According to PMBOK Guide, the Work Performance Data is “The raw observations and measurements identified during activities performed to carry out the project work. Examples include reported percent of work physically completed, quality and technical performance measures, start and finish dates of scheduled activities, number of change requests, number of defects, actual costs, actual duration etc.”

As per the definition, the Work Performance Data is raw information for the project’s current status which helps to create the Work Performance Information.

Work Performance Data is the input of below project management processes;

Examples for The Work Performance Data



Work Performance Data includes, but not limited to scope, time, cost, quality, communication, risks, procurement. Here below you can see some examples for the WPD.

Work Performance Information (WPI)



Work Performance Information is the processed, analyzed and integrated form of the Work Performance Data. Estimate to Complete, Cost to Complete, Schedule Variance, Cost Variance are some of the examples for WPI.

According to 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. Examples of performance information are status of deliverables, implementation status of change requests, and forecasted estimates to complete.”
Work Performance Information is created by using the Work Performance Data.

WPI is the output of below project management processes;

Keystones – Work Performance Data and Work Performance Information

  • WPD shows the project’s current status. On the other hand, WPI provides a comparison between the planned and the actual project performance.
  • WPD is used to create WPI.
  • WPD is raw and unorganized project information. On the other hand WPI provides processed, organized and structured project information which supports decision making.

Summary



PMP aspirants oftenly find WPD and WPI terms difficult to understand. WPD is raw, unorganized and observed data. It does not provide enough information about the current status of the project. On the other hand, WPI is organized, classified and interpreted. It is built by the help of WPD and provides adequate information for decision making.
Both of them are very important tools for project performance measurement and reporting.
