QNU
Earned Value Management They Say I
have to Do It,But Why???
By Ursula Kuehn, PMP, EVPUQN and Associates
QNU History of EVMS
• 1962-1965 PERT/Cost on Minuteman Missile• 1965 USAF created CSPCS (35 criteria)• 1967-1996 DOD issued C/SCSC (35 same
criteria)• 1996 DOD EVMS (NDIA initiative) (32 criteria)
• 1998 ANSI/EIA-Standard 748 (32 same criteria)
QNU
What Size of Project Requires EVMS?
• DoD requires on projects > $20M• DoT requires on projects > $6M• Dept. of Ed. requires on projects > $2M,
with a lighter version for projects < $2M
Do we see a trend?
QNU
10 Easy Steps for EVMS on all Projects
1. Define the project scope via a WBS2. Determine who will perform the work and
what it might cost3. Plan & schedule the defined work for the
agreed upon scope4. Determine points of management control5. Authorize budgets for the baselined plan
Adapted from Earned Value Management Project Management, Third Edition, Fleming and Koppelmen
QNU
10 Easy Steps for EVMS on all Projects (continued)
6. Define metrics to measure performance of work within each control point
7. Record actual costs of the work8. Measure control point performance and
determine project performance9. Forecast future performance10.Manage changes to the agreed upon
baseline

The Change Control Process
• Establish a change control board (CCB)
• Require the use of change request forms
• Keep a change control log
• For each approved change, a new PMB is established
