1. Using Earned Value Management System (EVMS) Briefing for ATC Engineering & Test Division (ACT-200) Managers and Leads
2. February 7, 2000 2 Briefing Objectives What is a Project?
What is a Program?
What is Project Management?
What is EVMS?
Why do we need EVMS?
How is EVMS Implemented?
Who will implement it?
3. February 7, 2000 Project Management Terms - IV Project -
A temporary endeavor
To create a unique product or service.
Program -
A group of related projects - e.g. DSR, VSCS, URET, STARS, ...as part of NAS
Managed in a coordinated way - ACT-200 Coordinating
Usually include elements of ongoing operations
4. February 7, 2000 4 Project Management Terms - I PM is the Application of Knowledge, Skills, Tools, and Techniques to Project Activities to Meet or Exceed Stakeholders Needs & Expectations.
Knowledge of general management practice & relevant application areas.
PM overlaps general management in many areas but they are not synonymous - e.g DSR vs. Division/Branch.
5. February 7, 2000 5 Project Management Terms - II Work Breakdown Structure (WBS): A deliverable-oriented grouping of project elements which organizes and defines the total scope of the project. Each descending level represents an increasingly detailed definition of a project component. Project components may be products or services.
6. February 7, 2000 6 Project Management Terms - III Work Package: Lowest Level of the WBS that may be Divided into Activities.
OBS: An Organizational Chart Relating Work Packages to Organization Units.
Responsibility Matrix: Relates Organization Structure to WBS & Ensures that each Element of the Projects Scope of is Assigned to a Responsible Individual.
7. February 7, 2000 7 Earned Value Management System (EVMS) - I EV - Tool for Measuring Project Performance
Compares work actually accomplished to work planned to determine if cost & schedule performance is as planned
EV is an Early Warning System
Helps management make proactive decisions to keep projects on course
8. February 7, 2000 8 Earned Value Management System (EVMS) - II EV Integrates Cost, Scope & Schedule measurements
EV Involves Calculating 3 key values for each activity
Budget - BCWS
Actual Cost - ACWP
Earned Value/Physical Progress - BCWP
Basis for variance analysis
9. February 7, 2000 9 Planning for EVMS - I Create a work breakdown structure
Organize work into discrete work packages and activities
Allocate a budget to each of the activities
Develop a schedule and Assign resources to accomplish each activity on the schedule
Be sure to include all work in the schedule
10. February 7, 2000 10 Planning for EVMS - II Award performance credit for physical % complete using any of these methods
0-100
Short duration tasks < 160 hours
EV is Zero until activity is complete
50-100
Duration less than 600 hours
50% at start of activity & 50% at completion
11. February 7, 2000 11 Planning for EVMS - III Interim milestone;
Duration less than 600 hours
Based on completed milestone for task
Level of Effort (LOE)
Long duration & consistent tasks
Difficult to measure - no deliverables
Measured by duration of time used e.g. 10 weeks support is 50% complete at 5 weeks
12. February 7, 2000 12 Tracking & Analysis Each update cycle/Reporting Period
Monthly or Bi-Monthly
Obtain physical % complete for each task
Calculate EV for each task
Sum up EV for all tasks as project EV
Calculate actual expenditure for actual work completed during the period
Compare the Cumulative EV to Actual expenditure
13. February 7, 2000 13 Elements of EV Analysis - I Performance indices relate value of work performed to dollar spent. e.g. CPI = 0.65 means that for every dollar spent, actual value of the work performed is $0.65.
Cumulative CPI used to forecast project cost at completion (also slide 17)
Cumulative SPI used to forecast project completion date (also slide 17)
14. February 7, 2000 14 Elements of EV Analysis - II Cost Variance - Difference between budgeted cost of work scheduled & actual cost of work performed
CV = BCWP - ACWP
Schedule Variance - Difference between budgeted cost of work scheduled & actual cost of work performed
SV = BCWP - BCWS
15. February 7, 2000 15 Elements of EV Analysis - II SPI - BCWP/BCWS
SPI => 1.0, Project Schedule performing as planned or better
SPI < 1.0, Project not performing as planned - needs help
16. February 7, 2000 16 Elements of EV Analysis - III CPI - BCWP/ACWP
CPI => 1.0, Project Cost performing as planned or better
CPI < 1.0, Project Cost not performing as planned - needs help
% Over/Under Budget - CAC - BCWS
17. February 7, 2000 17 Project Cost & Schedule Forecast Methods Estimate at Completion (EAC) is total cost to complete an activity, work package, or a project expressed as::
EAC = Actuals-to-date + Estimate to complete (ETC)
Cost EAC - BAC/CPI
Schedule EAC - BAC/SPI
18. February 7, 2000 18 EV Reporting Interpret the results of the calculations - Slides 8 - 11
Take or recommend corrective action as necessary
19. February 7, 2000 19 Conclusion EVMS provides management with an effective
tool for program planning and control
early warning system for program mgt.
EV Integrates Cost, Quality, & Schedule objectives when appropriately implemented
Must a baseline for measurements, and control at the start of project.
