According to the PMBOK Guide, specifically within the Control Schedule process, the calculated data used to communicate how the project is performing against the plan is known as Work Performance Measurements.
* Definition and Purpose: Work Performance Measurements are the calculated variances (such as Schedule Variance - SV) and indexes (such as Schedule Performance Index - SPI) for the various components of the Work Breakdown Structure (WBS).
* Communication to Stakeholders: These measurements are a primary output of the Control Schedule process. They are documented and communicated to stakeholders to provide a clear picture of the project ' s schedule status-specifically whether the project is ahead of, on, or behind the planned schedule.
* Evolution of Terms: In later editions of the PMBOK Guide, these measurements are often integrated into Work Performance Information, which is then used to create Work Performance Reports.
* Analysis of Other Options:
* A. Performance organizations: This is not a standard output or a term used to describe schedule performance data.
* B. Schedule baselines: The baseline is an input to the Control Schedule process. It is the approved version of the schedule used as a target to measure actual results against.
* C. Change requests: While these are an output of Control Schedule (when a variance requires a corrective or preventive action), they are a result of the performance analysis, not the data used to communicate the performance status itself.
