In the first three articles of this series, we reviewed Work Performance Information (WPI), Work Performance Measurements (WPMs) and Performance Reports. In this article, we'll recap the concepts and tie them together.
WPI includes status of deliverables, schedule progress, costs incurred, achieved value of technical performance measures, implementation status of change requests, status of risks etc. WPI is gathered as the project is being executed. WPI is an input to most M&C group processes. WPI is used to generate Work Performance Measurements (WPM) such as SV, CV, SPI, CPI and budget forecasts such as ETC, EAC. Together, WPI, WPMs and Budget Forecasts are used to generate Performance Reports.
As you can see, WPI includes the nitty-gritty details of the project. Do all the stakeholders like customer, sponsor, top management need to know every little detail of the project? It's way too much of information for them to consume. Some stakeholders may just be interested in the "big picture", while others may need to have a more detailed view. Performance Reports give stakeholders the information on how your project is progressing in the form of well-organized and summarized reports, at a level of detail that they require. The focus of Performance Reports is communication.
I hope this four part series helps you see the lines between Work Performance Information, Work Performance Measurements and Performance Reports clearly.
Part 1: Work Performance Information
