When comparing planned resource allocation against actual usage, the output generated is work performance information. This process involves assessing how resources are being utilized in relation to what was initially planned, thus allowing project managers to gauge the efficiency and effectiveness of resource use throughout the project's life cycle.

Work performance information consolidates data regarding the actual performance of various project elements, including resource usage. This output facilitates informed decision-making and enables project managers to identify discrepancies between planned and actual performance. By having this information, they can recognize areas needing attention, adjustments, or improvements, ensuring that the project remains on track.

Other options, while relevant in project management, serve different purposes. For instance, change requests relate to modifications in project scope or objectives but are not specifically linked to comparing resource allocation. Project documents updates involve revisions to documentation as the project evolves but do not directly result from resource allocation comparisons. The project management plan is a comprehensive document outlining how the project will be executed and controlled, rather than a direct result of resource performance evaluations. In summary, work performance information is the most appropriate output when analyzing resource allocation versus actual usage.
