This presentation by Wayne Abba from Abba Consulting provides a comprehensive overview of Earned Value Management (EVM) and its critical role in program resource management. It covers essential data elements and graphics, detailing how to conduct Earned Value Analysis (EVA), assess funding status, and manage baselines. Attendees will learn about the relationships among EVM data elements and the importance of resource management, including labor, materials, and costs. The session explores practical scenarios, variance analysis, and the integration of cost-schedule data for effective program oversight.

Resource Management • Earned Value Management = Resource Management • Resources are labor, material and other direct and indirect costs required to execute the program • FAA applies EVM at Program level to include prime and subcontractors, government FTEs, support contractors • Managed in dollars, hours, or any measurable unit • Cost and schedule data summarized directly from contracts and programs for management and reporting at all levels
Budgeted Cost for Work Scheduled Budgeted Cost for WorkPerformed Actual Cost of WorkPerformed - Approved baseline time-phased plan for resources to be consumed (e.g. 100 hours) - Work accomplished in terms of planned resources(e.g. 100 hours) - Actual cost of the resources consumed(e.g. 120 hours) - Reconcilable to accounting system EVM Terminology and Resource Management Assume basic understanding – Earned Value Management Concept and Terminology

Earned Value Analysis • Earned Value Analysis = Understanding the relationships among the EVM data elements • EVM discipline provides confidence • Contractor and PM management systems are adequate • Data are summarized from the Control Account level, where technical/schedule/cost integration occurs • Use the data for management and oversight • Data quality becomes “self-policing” • Ask questions – be an informed, critical consumer

Normal Baselines cont’d • Management System • Does management system meet ANSI EVMS guidelines? • Are managers trained? • Are EVM techniques objective? • Is “Level of Effort” scope properly categorized? • The Bottom Line • Does the program have an executable plan that integrates scope, planned cost and schedule resources and risk? • If “no,” go slow… better to do it right than to fail
