HKSM

Unprocessed observations and measurements captured while project tasks are being performed.

Key Points

• Represents raw facts collected during execution (no analysis or interpretation).
• Typically includes actual start/finish dates, percent complete, costs spent, quantities, and defect counts.
• Gathered through logs, timesheets, sensors, test results, and other collection tools as work occurs.
• Serves as input to produce work performance information and, later, work performance reports.

Example

During construction, the site engineer records that concrete pour #12 used 18 m^3, started at 08:10, finished at 11:35, and two defects were noted. These unprocessed entries are work performance data.

PMP Example Question

While executing the project, the team logs actual start and finish times, the number of defects found in testing, and the hours worked per activity. What are these records called?

1. Work Performance Data
2. Work Performance Information
3. Work Performance Reports
4. Lessons Learned Register

Correct Answer: A — Work Performance Data

Explanation: These are raw, unprocessed observations and measurements collected during task execution. Analysis and contextualization would turn them into work performance information, and formal presentation would produce reports.
