ENTC 419 Technical Project Management Electronics and Telecommunications Engineering Technology Earned Value
Status Updates • White Paper Presentations: • Legendary Applications – 80 • Dynamic Design -- 88 • Extra Credit proposals • Meeting scheduled for Legendary Applications? • Presentation and Review Sessions • CDD – Graded and returned -- Wednesday • NLDs – Monday after spring break • Others • ELE seminars – Guest approved by week 9
Tasking • Review all requirements for Formal Technical Proposal (FTP) • Have questions ready for discussion
Project Control • Need quantitative tools • Assess project “health” • Normalized for magnitude • Fair and impartial • Trends important • Easy to utilize • Scaleable
Basic Concepts • All linked to “Budgeted Time and Cost” • Each task or unit of work has a cost and a time associated with it in the plan • Need to get “big picture” view of entire project • Compare planned vs. actual performance • Allow for variations at lower levels • “Earned Value” method is used widely in private sector
Project Control • Earned Value • Cost Metrics • BCWP – Earned Value • BCWS – Planned Value • ACWP – Actual Value • Calculated Values • Variances • Cost (CV) • Schedule (SV) • Indices • Cost Performance (CPI) • Schedule Performance (SPI)
Earned Value Definitions • BCWS (Planned Value) • What should be done • Budgeted Task Cost x %Task Scheduled • BCWP (Earned Value) • What is done • Budgeted Task Cost x %Task Completed • ACWP (Actual Value) • Cost to achieve what is done • Actual Task Cost of Work Performed
Earned Value Terms Budget Cost of Work Performed = BCWP(Earned Value) Budget Cost of Work Scheduled = BCWS(Planned Value) Actual Cost of Work Performed = ACWP(Actual Value) Schedule Variance: SV = BCWP – BCWS (Earned – Planned) Cost Variance: CV = BCWP – ACWP (Earned – Actual) Schedule Performance Index: SPI = BCWP/BCWS (Earned/Planned) Cost Performance Index: CPI = BCWP/ACWP (Earned/Actual)
Budgeted at Completion (BAC), Estimated at Completion (EAC), Variance at Completion (VAC) EAC VAC BAC $540,000 ETC VAC = BAC-EAC EAC = ACWP + ETC EAC = BAC/CPI EAC = BAC * ACWP BCWP ACWP 16 Weeks

Class Assignment • Determine the Earned Value BCWP, BCWS, ACWS, CV, SV, CPI and SPI for the example project • Plot these values on the Earned Value graph • Why is it better to use indices than variances? • Determine and plot BAC, EAC, and VAC
