 What are the differences among EV, EVM,
and an EVMS?
 EVM Budget vs. Funds
 Resources and current initiatives within
NASA

3.
 Value of work accomplished expressed in terms of
hours or dollars
 Calculated using an EV method assigned to a
work package, e.g.
 Level Of Effort (LOE) - value is earned based on the
plan; appropriate for work scope with no defined
products
 % Complete – value is earned based on quantifiable
measure of progress
 0/100 – all value is earned upon completion; appropriate
for tasks that start and complete within one month
 50/50 – half of the value is earned when the task is
started and the other half when complete; appropriate
for tasks that span two months with equal work in each
 Milestones – value is earned when milestones are
complete

 Utilizing this new measure (EV) in project
management decision making to:
 Calculate cost and schedule variances
 Schedule Variance (SV) = EV – Plan (PV, BCWS, or S)
 Cost Variance = EV – Actuals (AC, ACWP, or A)
 Identify significant cost and schedule variances and
their drivers
 Develop corrective action plans to get back on
track
 Forecast future cost and schedule performance
 Summarize the data to support management needs
 EVM is both performance measurement (i.e.,
what is the program status) and performance
management (i.e., what we can do about it)

 We are at the end of Mar-09, and this is where we are
 We finished the Fire & Leak Detector Bracket and Stand
Fabrication
 We are still not finished with Distribution Box Wiring
 We finished the Terminal Distributor Fab.
 We fabricated 6 of 10 cables*
 The actual costs are as follows:
 Jan-09 = $9,000
 Feb-09 = $4,000
 Mar-09 = $10,000
 How am I doing and where will I end up?
* Assume cables are of equal complexity

 Our budget through Mar-09 for the Hazardous Gas
Detection System was $21,800
 We spent $23,000, so we are overrunning our plan

 The project manager is anticipating that the most likely
scenario is that the remaining work will be finished with
the same efficiency as the past and is predicting to
overrun cost by $6,182. In a best case scenario, the
remaining work will be completed on cost, and the
project will overrun by $4,680.
 The project manager evaluated the remaining work and
thinks that the remaining 4 cables will be fabricated and
the distribution box wiring will be completed in April-
09. The Haz Gas Detection System will finish on
schedule.*
 Using traditional cost management, the cost variance is
significantly understated and no assessment of
schedule can be made.
* SV goes to zero when work is completed

13.
 An organization’s internal management systems for
planning and control, including processes for:
 Planning all authorized work scope to completion
 Assigning authority and responsibility at the work performance
level
 Integrating cost, schedule, and technical aspects of the work
into a detailed baseline plan
 Measuring progress objectively (earned value) at the work
performance level
 Accumulating and assigning actual costs
 Analyzing variances from plans
 Summarizing and reporting performance data to higher levels
of management for action
 Forecasting achievement of milestones and completion of
contract events
 Forecasting final contract costs and
 Maintaining a baseline in a disciplined fashion and
incorporating revisions in a timely manner

14.
 Every company or government agency uses some form
of business planning and control systems for
management purposes
 When a project is deemed critical, the customer
requires more rigor in the supplier’s internal planning
and control systems to ensure performance data and
forecasts are valid, accurate, and timely.
 The EVMS guidelines have been published as an
American National Standards Institute/Electronic
Industries Alliance standard ANSI/EIA-748, Earned Value
Management Systems
 The guidelines are broad enough to allow for common sense
application
 Most of the basic principles of an EVMS are already inherent in
good business practices and program management
 Suppliers required to produce EV data are required to
be in compliance with, or validated against, ANSI EIA-
748

What is Budget? What are Funds?
 Budget is created as an aid to the  Funding is process of supplying
management process money to the project
 Cannot be spent  Known by many names such as
• A number written on a piece of money, funding limits (obligations),
paper (an objective) actuals
• A representation of work  Total costs for entire project
• A planning vehicle • Experienced cost for work
• A temporary element for performed – actuals or ACWP
project control • Expenditures & estimates of
future spending for remaining
project elements
 Can be planned - BCWS  Estimate To Complete (ETC)
 Can be earned - BCWP
 BAC  Estimate At Complete (EAC)

 Budget
 Budgeted Cost for Work Scheduled (BCWS)
 Time phased budget spread of required resources for the entire task
 Assigned (budgeted) value of the work (at any level; WP, CA, IPT, Project)
 Forms the Performance Measurement Baseline (PMB)
 Budget At Completion (BAC)
 Budgetary number representing ALL authorized work
 Cannot change without a change to scope/technical content, i.e.
requirements change
 Funding
 Estimate To Complete (ETC)
 Funding required to complete remaining work
 When added to ACWP, it results in the EAC
 Estimate At Completion (EAC)
 Funding number representing ALL the money that will be spent
 Can (and will) change without a commensurate change to technical
content
