What is EVM?
EVM is the project management tool...
Are we there yet?How much longer before we’ve arrived?What can we do about it?

Main metrics :PV - Planned Value
The portion of work expected to be completed at a given date, times the authorized budget allocated to carry out that work
EV - Earned Value
The value of completed work expressed in terms of the budget assigned to that work
AC - Actual Cost The costs actually incurred and recorded in accomplishing the work performed

Earned Value: Cheat Sheet
Schedule Variance SV = EV–PV In currency. Negative means delay
Schedule Performance Index
SPI = EV/PV < 1 means delay
Cost Variance CV = EV-AC In currency. Negative means overcost.
Cost Performance Index
CPI = EV/AC < 1 means overcost
Estimate At Completion
EAC = BAC / CPI Forecast final cost
To Complete Performance Index
TCPIBAC = (BAC-EV)/(BAC-AC)
Can we catch up?

Benefits of EVM
Requires development of integrated baselineResults in better project definition and planning
Early identification of trends and problems Accurate picture of project status
Cost, schedule, and technicalsegregation of schedule and cost variances
Projection of final costs Project control by the team
Enables project manager to make informed decisions based on facts
Results in successful projectsOn time, on cost

PMBOK
WBS: Work Breakdown Structure, hierarchical list of all the activities to be performed to complete the project.
Workunits: The “Leaves” of the WBS tree. Activity small in size/duration, under responsibility of one person.
Workunits use Resources (money, people) to produce Deliverables
Terminology
Where can EVM be Applied?
EVM suitable for projects that have:• Clear definition of work scope• Project schedule range from a few months to
many years• Small to very large cost
• Technically complex and demanding,i.e. that cannot be fully specified in the front-end phase;
• Long makespan: economic effects like inflation• Involving many contributors, contractors, suppliers...
i.e. many activities that are outsourced, result-oriented.
What is a large-scale project?
Agenda
EVMS concepts NICA project EVM web-based application
NICA
Is NICA large-scale project?
NICA
Work planned for period from year 2012 till 2017 Estimated cost is more than 100M $ Tasks to complete:
• General Infrastructure• Accelerator• MPD Detector
All the work have to be well coordinated
LHC Accelerator and Detectors
Project audit of 2001
18% overspend announcement … only
Technical Coordinator → “the project is behind
schedule” Project Administrator → “the project is under-running” LHC Team: not is position to demonstrate that the
project could be completed within allocated budget!
Member States asked the LHC Project Management to set up
a formal Project Control System
EVM-based project control system
Deliverable-oriented physical progress monitoring
Interfaced to accounting systems,
to get accurate information on actual costs
Excel spreadsheets to interact with DBs
Web-based

Outcome of EVM experience…
Re-established trust• Cost and Schedule Review Committee:
‘world class’• CERN management was formally
congratulated by Member States• Further overruns were discussed in the
context of proven project control.
Project culture at CERN and cost awareness of project engineers have improved.

Conclusion
Objectively measures performance of the project as it moves from project initiation through project closure.
Provides early warning of potential project adverse performance.
Shows Opportunity associated with positive schedule variance.
Enables the management of risk associated with underwriting or insuring against negative schedule variance.
Provides a means to forecast future performance based upon past performance.
