EVM is the project management tool...
Are we there yet?
How much longer before we’ve arrived?
What can we do about it?

performance measurement
how am I doing against my baseline plan?

performance management
what do I need to do to bring the project in on cost
and schedule?
 Preparation

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

•Are we ahead or behind schedule?
•Are you getting value for money?
•Did you spend money on the right things?

 Requires development of integrated baseline
Results in better project definition and planning
 Early identification of trends and problems
 Accurate picture of project status
Cost, schedule, and technical
segregation 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 projects
On time, on cost

 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
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 frontend phase;
• Long makespan: economic effects like inflation
• Involving many contributors, contractors, suppliers...
i.e. many activities that are outsourced, resultoriented.

NICA project

EVM web-based application
Is NICA large-scale project?
 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
 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

 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.

Reminders for progress reporting
 Crosstab to drill drown through the WBS structure (or
other dimension…)
 PV, EV, AC Charts at every
WBS level
 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.
