Earned Value Management (EVM) is a powerful method integrating scope, schedule, and resources. Learn how to get started, use it as a reporting and decision-making tool, and interpret key EVM language like BCWS, ACWP, and BCWP. Discover how EVM aids in project planning, forecasting, and communication. Key topics include SV, SPI, CV, CPI, BAC, ETC, and more. This guide provides detailed steps on creating a Performance Measurement Baseline, managing scope, scheduling work packages, and budgeting resources effectively. Explore EVM graphs, examples, and practical applications in project management.

Earned Value Management How do we get started?
What is it? • A planning process • An internal policy • A contract requirement • A way to measure performance • A way to identify problems • A forecasting tool • A way of doing business
What is it? A way to integrate scope, schedule, and resources all at once!
How is it used? • A reporting tool • Satisfy the contract reporting requirements • “filling the square” • As a decision-making tool • To evaluate project planning • To communicate status • To forecast resource needs
Language of EVM • Budgeted Cost of Work Scheduled (BCWS) • The plan to spend budget • Actual Cost of Work Performed (ACWP) • The costs of the work that has occurred • Budgeted Cost of Work Performed (BCWP) • What was performed (what it should have cost) • This is EARNED VALUE
Language of EVM • Schedule Variance SV = BCWP – BCWS • On/Off plan in dollars (>0 is ahead, 0 is on target, <0 is behind) • Schedule Performance Index SPI = BCWP/BCWS • On/off plan as a ratio (>1 is ahead, 1 is on target, <1 is behind) • Cost Variance CV = BCWP – ACWP • Over/under running (>0 is underrun, 0 is on target, <0 is overrun) • Cost Performance Index CPI = BCWP/ACWP • Return on actual costs (>1 is under, 1 is on target, <1 is over)
Language of EVM • Budget Authority for unknowns • Management Reserve • Budget at Complete, BAC • The budget to do the work • Estimate to Complete, ETC • Estimate of the cost to do the remaining work • Estimate at Complete • Best guess of cost of entire cost of project • Latest Revised Estimate • Contractor’s best guess of cost of entire cost of project

How do we do this? • Performance Measurement Baseline • Scope • Identify the scope of work • WBS • Extend to Work package level
How do we do this? • Performance Measurement Baseline • Schedule • Arrange work packages in order • Schedule start and finish • Classify work and choose EV technique
How do we do this? • Performance Measurement Baseline • Budget • Identify needed resources (budget) • Spread budget • Calculate Cumulative BCWS
How do we do this? • Performance measurement baseline Graph Cum BCWS
