Comment évaluez-vous l’exactitude et la fiabilité de vos données et hypothèses EVM ?

Evaluating the accuracy and reliability of your Earned Value Management (EVM) data and assumptions is crucial in project management. A primary step is regular review of your Work Breakdown Structure (WBS) and Organizational Breakdown Structure (OBS). Both should be updated to reflect the current project scope, schedule, and resources. Regular data quality checks are essential to verify the accuracy of the collected data. Ensure that the data used for EVM calculations is based on reliable and up-to-date information. Finally, validate your EVM assumptions throughout the project lifecycle, adjusting as necessary. Regular audits and reviews can help maintain the accuracy and reliability of your EVM data and assumptions

We can validate the planned value PV in points 1.we have to check the project plan by ensuring the planned value with the project schedule and the budget allocated to each task or work package. 2.we have to compare it with the baseline to define the deviation . and We can validate the Earned value EV in points : 1.Confirm that the EV is based on actual progress and work completed. 2.Ensure that the criteria used to measure progress and determine earned value are align with the project plan. 3.check EV calculations using Earned Value Management (EVM) formulas.

Validate Earned Value (EV): Define Measurable Milestones: Clearly define the criteria for earned value measurement, such as completion of deliverables, milestones, or percent complete estimates for work packages. Use Objective Measurement Methods: Employ objective methods for measuring earned value, such as physical progress, completion of specific tasks, or achievement of predefined criteria. Compare EV to Actual Progress: Validate that the earned value reflects the actual progress achieved on the project. Compare EV to completed work and milestones to ensure consistency and accuracy. Consider Quality and Performance: Take into account the quality and performance of completed work when measuring earned value.

Validate Planned Value (PV): Review Work Packages and Activities: Ensure that the scope of work within each work package or activity is clearly defined and aligned with the project's WBS or PBS. Verify Schedule Baseline: Compare the planned start and end dates for activities against the project schedule baseline. Any deviations may indicate discrepancies in planned value calculation. Assess Resource Availability: Validate that the planned resource allocation (e.g., labor hours, equipment usage) aligns with resource availability and capacity. Review Assumptions and Constraints: Evaluate the assumptions and constraints underlying the planned value calculations. Ensure that they are realistic and accurately.

The main aim of the EVM formulas is to assess the efficiency and effectiveness of the performance and progress and to analyze these variances, in order to know the project's current status and the forecasted performance and progress. So, You have to care more about these formulas and indices and make sure the results reflect the project status, to make a decision for corrective or a decision for reinforcement.

Evaluate EVM data by comparing planned vs. actual costs and schedules. Analyze variances to identify discrepancies and adjust assumptions accordingly. Utilize Monte Carlo simulation for robust risk analysis. For instance, in a solar energy project, validate EVM data against real-time performance metrics like energy output to ensure accuracy and reliability.
