6 4 Control Costs
6.4 Control Costs Explained
Control Costs is a critical process in project management that involves monitoring the status of the project to update the project costs and managing changes to the cost baseline. This process ensures that the project stays within the defined budget and delivers the expected value. Here, we will delve into three key concepts of Control Costs: Cost Performance Measurement, Earned Value Management (EVM), and Cost Forecasting.
1. Cost Performance Measurement
Cost Performance Measurement involves tracking the actual costs incurred against the planned budget. This measurement helps in identifying variances between the planned and actual costs, allowing for timely corrective actions to keep the project on track.
Example: For a construction project, cost performance measurement might involve comparing the actual costs of materials and labor to the budgeted amounts. If the actual costs exceed the budget, the project manager can investigate the reasons and take corrective actions, such as reallocating resources or negotiating better prices.
2. Earned Value Management (EVM)
Earned Value Management (EVM) is a technique used to integrate scope, time, and cost data to assess project performance. EVM calculates three key metrics: Planned Value (PV), Actual Cost (AC), and Earned Value (EV). These metrics help in understanding the project's current status and predicting future performance.
Example: In a software development project, the Planned Value (PV) might be the budgeted cost for the work scheduled to be completed by a certain date. The Actual Cost (AC) is the actual cost incurred for the work performed. The Earned Value (EV) is the budgeted cost for the work actually completed. By comparing these metrics, the project manager can determine if the project is ahead of, on, or behind schedule and if it is under, on, or over budget.
3. Cost Forecasting
Cost Forecasting involves predicting the future costs of the project based on current performance data. This forecasting helps in anticipating potential cost overruns and taking preventive measures to keep the project within the budget. Common forecasting techniques include Estimate at Completion (EAC) and To-Complete Performance Index (TCPI).
Example: For a marketing campaign, cost forecasting might involve calculating the Estimate at Completion (EAC), which is the expected total cost of completing all the work. The EAC can be calculated using various methods, such as assuming the remaining work will be completed at the budgeted rate or at the current cost performance rate. The To-Complete Performance Index (TCPI) can also be used to determine the cost performance that must be achieved for the remaining work to meet the budget.
