What type of project data should be reviewed for an accurate understanding of project progress?

Reviewing actual work hours or actual duration is essential for gaining an accurate understanding of project progress because it provides concrete evidence of what has been accomplished compared to what was planned. This type of data reflects the real time spent on tasks and activities, allowing project managers to assess how well the project is adhering to its timeline, budget, and overall objectives.

By analyzing actual work hours, project managers can identify variances between planned and actual performance. This insight can lead to informed decision-making about resource allocation, task adjustments, and timeline forecasts. Understanding the discrepancy between what was anticipated and what has been completed is crucial for effective project control and for taking corrective actions where necessary.

In contrast, planned work hours can provide a baseline for what is expected but don’t reflect the reality of progress made. Estimated completion time tends to be a projection and may lack the accuracy needed for assessing current status. While team feedback is valuable for qualitative insights and morale, it doesn't provide the quantitative data crucial for tracking project metrics. Therefore, actual work hours or actual duration is the most reliable indicator of project progress.
