A systematic methodology provides metrics to evaluate project performance against its planned budget and schedule. It accomplishes this by integrating scope, schedule, and cost data to provide objective measurements of project progress. This process hinges on calculating three key values: Planned Value (PV), Actual Cost (AC), and Earned Value (EV). Planned Value represents the authorized budget allocated to scheduled work. Actual Cost reflects the expenses incurred to complete the work. Earned Value represents the value of the work actually completed. For example, if a project is budgeted for $100,000, with $25,000 allocated to a specific task, the Planned Value for that task is $25,000. If the task is completed but cost $30,000, the Actual Cost is $30,000. If the task is fully completed, then Earned Value also is $25,000.
This methodology offers significant benefits, allowing for early detection of potential issues and enabling proactive corrective actions. By monitoring key performance indicators derived from the calculated values, stakeholders gain visibility into project status, facilitating informed decision-making. Early indications of cost overruns or schedule delays provide opportunities for mitigation strategies to be implemented. This technique emerged as a formal management process in the 1960s within the U.S. Department of Defense and has since become a widely adopted standard across various industries.
