What type of data helps compare the percentage of work completed against the performance measurement baselines?

• A. Project documents
• B. Organizational process assets
• C. Work performance data
• D. Project management plan

Answer: (C)

The type of data that helps compare the percentage of work completed against the performance measurement baselines is work performance data. This data provides insights into what has been accomplished in the project so far, allowing the project manager and team to measure actual performance against the planned performance metrics outlined in the baselines.

Work performance data includes metrics related to the project's deliverables, schedule, and resource usage, which are crucial for determining if the project is on track or if adjustments are necessary. By assessing this data, project managers can identify variances, analyze their implications, and take corrective actions if needed to ensure the project remains aligned with its objectives.

Other options, like project documents, organizational process assets, and the project management plan, do not serve the specific function of offering insights into performance measurement comparisons. Project documents may contain various information but lack the focused metrics. Organizational process assets relate to practices and knowledge from previous projects but don't provide real-time performance data. The project management plan outlines how the project will be executed and controlled but does not provide the actual completion statuses against the baselines.
