Why is earned value used in scheduling?

Earned value is a project management technique that integrates scope, schedule, and cost parameters in order to provide a comprehensive assessment of project performance. Its primary purpose in scheduling is to quantify schedule performance against the plan by measuring how much work has actually been completed at a specific point in time compared to the planned progress. This involves using metrics such as Earned Value (EV), Planned Value (PV), and Actual Cost (AC) to analyze variances and trends.

Through earned value analysis, project managers can identify whether the project is ahead of schedule, on schedule, or behind schedule, providing valuable insights for decision-making and corrective actions. This quantification enables a clear picture of schedule performance, allowing stakeholders to understand the current status of the project in relation to the original timeline, making it a critical tool in effective project management.

In contrast, other options focus on different aspects of project management. For instance, allocating resources effectively pertains more to resource management than to the quantification of schedule performance, while assessing individual team performance and determining project profitability relate to performance assessment and financial analysis, rather than the core purpose of earned value in the context of scheduling.
