Earned Value BasicsEarned Value In a Nutshell
  • What is more important?
  • Knowing where you are on schedule?
  • Knowing where you are on budget?
  • Knowing where you are on work accomplished?
  • It compares the PLANNED amount of work with what
    has actually been COMPLETED, to determine if COST
    , SCHEDULE, and WORK ACCOMPLISHED are progressing
    as planned.
  • Work is Earned or credited as it is completed.
  • Did we get what we planned, for the amount of
    money we planned to spend, and did we get it when
    we needed it?

Earned Value BasicsProject Analysis Without
Earned Value?Gantt Charts
  • Most used PM tool for representing phases and
    activities of a WBS
  • A clear way of showing schedule status to your
    sponsor and team
  • Great for small projects but can be hard to read
    for larger projects with many dependencies
  • Only show part of Triple Constraint (focus on
    schedule management)
  • Married to waterfall development
  • Does not adequately represent project size or
    size of the work element
  • Magnitude of behind schedule condition can be
    misleading
  • If two projects are the same of days behind
    schedule
  • Which of the two has the larger impact on
    resource utilization?
  • Gantt does not represent the difference
  • Gantt does not show resource management
  • Does not indicate if the task is front or
    back loaded
  • complete may be miss-represented

Earned Value?Budget Spend Plan
  • Medium to Large Projects S Curve Project
    Spend Tracking
  • Provides a budget baseline for tracking actual
    costs against periodic budget targets.
  • Start by creating a time-phased budget by
    plotting your weekly, monthly, quarterly budgeted
    costs or hours (time and dollars)
  • Use MS Project baseline estimated project costs
    and plot graphically over time, they usually
    result in an S curve
  • Add MS Project actuals to plot dotted lines at
    each chosen interval to track variances.
  • Provides a simple Top-Level view of project
    financial performance useful for status reports
    and dashboards.
  • If you dont have labor rates you will need to
    use budgeted vs actual hours.
  • Challenges
  • Works fine if your project is on schedule Spend
    plan still needs additional status information
    (for example Gantt)
  • If behind schedule PM may not be able to
    understand project status from this graph
  • Actual budget could be in worse or better shape
    than shown
  • If your budget spend shows overspending and your
    schedule shows milestone slippage you know you
    are in trouble. You may not be able to tell how
    bad the trouble is.

Earned Value Basics Minimal Requirements
  • EVM Requires 3 values
  • Planned Value (PV) - Baseline
  • Actual Costs (AC) Based on Time Entry or Cost
    Entry
  • Earned Value (EV) What you earned
  • Work is Earned or credited as it is completed.
  • Did we get what we planned, for the amount of
    money we planned to spend, and did we get it when
    we needed it?
  • Answer
  • Where have we been?
  • Where are we now?
  • Where are we going?

10
Earned Value Basics Minimal Requirements
Term Interpretation
(PV) Planned Value Replaces BCWS How much work you planned to have accomplished by now? The budgeted costs of the work scheduled The projects time-phased budget Can only change when baseline is changed
(AC) Actual Cost Replaces ACWP What is the actual cost incurred ( / Hours) The actual costs of the work completed during the month or reporting period Actual costs by work code Requires accurate charging of staff time to appropriate control account
(EV) Earned Value Replaces BCWP What is the estimated value of the work actually accomplished? The projects physical progress Progress reported in baseline or planned dollars Represents sum of completion for each task or deliverable
Planned value and Actual Cost will be compared to Earned value in terms of differences / ratios Will result in variances and performances indexes Planned value and Actual Cost will be compared to Earned value in terms of differences / ratios Will result in variances and performances indexes

  • Step 10 Manage Scope Through Change Control

14
Earned Value Framework Steps to Success
Planning Step 1 Define the Scope
  • Scope Definition
  • Single most important factor to a sound EVM
    process and implementation
  • Work Breakdown Structure
  • Roadmap for analyzing the project progress and
    performance
  • Each element of the WBS is broken down into
    pieces each piece defines responsibility to a
    person for that element
  • 100 of scope What is not in the WBS is not in
    scope
  • Work is broken down into measurable work packages
  • Focus on authorized work
  • Must be firm Critical for Earned Value Projects
  • Break the Work Packages into activities of the
    project. These should be included within your
    WBS and will produce the project schedule
    activities.
  • Organization Breakdown Structure (matrix
    organizations)
  • Relates WBS elements at the work package level to
    the organizational unit responsible for
    completing the work

15
Earned Value Framework Steps to Success
Planning Step 2 Determine Who Will Perform the
Work
  • Who will perform the work?
  • Determine Skill Level
  • Experience is faster but more costly
  • Task identification takes place during this step
  • Make or Buy Decision (Internal or Sub
    Contracting)
  • Will all or some of your project be outsourced?
  • Internal projects (Make Decision) has some cost
    flexibility
  • Scope definition critical for external (Buy
    Decision)
  • Contracts are unforgiving Cost to change can be
    excessive
  • Critical to get scope right because cost to
    change can be excessive
  • Responsibility Assignment Matrix (RAM)
  • Tied to the WBS with the OBS
  • Responsibly Chart for activities

16
Earned Value Framework Steps to Success
Planning Step 3 Plan and Schedule Work
  • Scheduling is vital to Earned Value
  • Formal scheduling system (i.e. MS Project) is
    required
  • EV is nothing more than Scheduling system,
    authorized scope, timeframes, and budgets
  • Reflects PMs baseline Planned value (PV) for
    everyone to follow
  • Critical Path (Task Sequencing)
  • Which tasks are sequential? Parallel
  • Network Diagramming tools
  • Must be aggressively managed when negative earned
    value schedule variances are discovered.
  • Will help determine which task variances receive
    the most attention
  • High risk tasks must also be identified for same
    reason
  • Begin Scheduling

17
Earned Value Framework Steps to Success
Planning Step 4 Establish Resources and Budgets
  • Establish resource requirements (budgets) for all
    defined tasks
  • Start-up sequence may be different for your
    organization
  • Scope, Schedule, and Budget vs. Scope, Budget,
    Schedule
  • Best practices should be iterative but SCOPE
    DEFINITION MUST COME FIRST
  • Enter resources for each task
  • Determine the costs for the activities
  • Labor rates per task hour
  • Fixed cost per activity or work package (need to
    be spread across each lower level activity)
  • Risk Analysis and Risk Management Plan
  • Resource Leveling Exercise
  • Management will then approve the budget
  • Contingency Never include contingency in an
    individual task why?
  • Will most likely cause a variance
  • Contingencies and other reserves should be
    isolated and owned by the PM
  • Must plan/schedule all defined tasks along with
    the authorized budget necessary to complete each
    task. This is required to have a viable project
    baseline.

18
Earned Value Framework Steps to Success
Planning Step 5 Determine Performance Metrics
and Thresholds
  • How is planned value completion measured?
  • EV Systems rely on the effective collection of
    the Performance and the Costs.
  • There are basically 2 types of methods of
    collecting the Performance
  • Discrete something tangible to measure against
  • 0/100 no EV credit until 100 of work is
    completed.
  • 50/50 and 25/75 some EV credit at 25 or 50,
    remaining EV at close of Work Package
  • Weighted Milestone Each completed milestong
    completion earns a percentage of EV. Must be
    individually valued. May also consider monthly
    milestones
  • Physical Complete ie. 5 start, 50 unit
    test, 75 code review, 100 signoff
  • Complete based on hours necessary to complete
    the task (common) least desirable
  • Units completed For physical counts of product
    or outputs
  • Incremental milestones - complete based on
    individual milestone completion
  • Non-discrete where the measuring of performance
    is not associated with anything tangible
  • Level of effort should only be used when schedule
    performance is of no importance. A level of
    effort package can never give an indication of
    the work that has actually been performed (PV)
    will always equal the schedule work (PV)

19
Earned Value Framework Steps to Success
Planning Step 6 Create Performance Measurement
baseline and Mgmt Control
  • Earned Value requires a baseline project schedule
    (time-Phased budget baseline)
  • Indirect costs could be included in some
    commercial type contracts
  • Schedule Management focuses on the schedule
    performance of the project.
  • It looks at the relationships between the
    Earned Value (EV) and the Planned Value (PV).
  • This will be your Planned Value (PV) for the life
    of the project
  • Remember, MS Project can handle multiple
    baselines but you should always measure against
    the last baseline required by the stakeholders.
  • This information will be plotted into a
    traditional S Curve diagram.
  • Results should be added to the Performance
    Management Plan
  • See Next Slide for an example

Is this Good or Bad?
  • Actual costs are below planned costs (good news?)
  • Unless you look at the planned costs of the
    completed work, you dont know if this is good or
    bad
  • That is exactly what is missing and what Earned
    Value will tell you

23
Earned Value Framework Steps to Success
Executing Step 7 Record Direct Costs
  • Purpose is to show how much money they have spent
    on a project
  • Update the schedule with the period progress
  • PMs are required to enter actual hours on a
    consistent basis
  • Costs from invoices are also entered
  • After actuals are entered cost and schedule
    variances can be calculated
  • This is where discrete measures come into play
  • Earned value must then be relatable to the actual
    costs in order to determine the cost efficiency
    factor, called the Cost Performance Index (CPI).
  • The CPI is likely the single most important
    metric for any project employing earned value.
  • To-Complete Performance Index (TCPI)

Against Baseline (Control Step)
  • Next Calculate all Earned Value components
  • Determine cost and variances from baseline
  • Determine three Required Values (PV budget, AC
    (Actuals) EV for the work accomplished to date
  • Tip EV is based on a of your budget We
    have actually completed worth of work
  • Calculate Variances, indices and factors from
    baseline
  • Variances (SV, CV, SPI)
  • Performance Indexes (CPI, SPI) -- ratio
    expressions of the Schedule and Cost Variances
  • PMs should focus on exceptions using thresholds
    determined during planning
  • Management by Exception (Lessons Learned)
  • Cannot simply review parent tasks or phases
  • What if there is a negative task and a positive
    tasks.
  • Both will need attention
  • How critical is the task? Is it on the critical
    path or is it a high risk task?
  • Start at the higher levels of the plan and work
    your way down
  • Cost overruns are typically non-recoverable.

Earned Value Terminology Steps to Success
Controlling Basic EV - Summary
Term Interpretation
(PV) Planned Value This is your baselined budget as approved by your stakeholders
(AC) Actual Cost These are your actual hours and costs as entered by the project team. PM must (at a minimum) audit these to verify Discrete Entries Verify if work completed is DONE
(EV) Earned Value What is the estimated value of the work actually accomplished? The projects physical progress Progress reported in baseline or planned dollars Represents sum of completion for each task or deliverable
(BAC) Budget at Completion The sum of all of the budgets allocated to a program. How much did we Budget for the Total Job.
Planned value and Actual Cost will be compared to Earned value in terms of differences / ratios Will result in variances and performances indexes Planned value and Actual Cost will be compared to Earned value in terms of differences / ratios Will result in variances and performances indexes
27
Earned Value Terminology Steps to Success
Controlling Variance Calculations
Term Interpretation
(SV) Schedule Variance Represents the difference between the amount of work actually completed and the amount of work scheduled to complete. This variance tells us if the schedule is ahead or behind what was planned for during this period of time.
(CV) Cost Variance This is the Difference between the estimated and the actual cost to complete the same work. The cost variance tells us if the costs are higher than budgeted or lower than budgeted.
(VAC) Variance at Completion Represents how much over/under budget will we expect to be at the end of the project It calculates the difference between the budget at completion and the estimate at completion.
28
Earned Value Terminology Steps to Success
Controlling Variance Calculations
1 lt1 gt1
(SV) Schedule Variance (EV PV) On schedule Poor Performance If SV is less than 1.0 than your project is behind schedule. Less work completed than planned Good Performance If SV is greater than 1.0 than your project is ahead of schedule More work has been accomplished than scheduled
(CV) Cost Variance (EV - AC) On budget Poor Performance If CV is less than 1.0 than your project is over budget. You have cost overruns Typically not recoverable Will continue to deteriorate unless corrective action is taken to mitigate Good Performance If CV is greater than 1.0 than your project is under budget You have cost under runs
(VAC) Variance at Completion (BAC EAC) A negative number means we are doing poorer with costs than we anticipated A positive number means we are doing better with costs than we anticipated
REQUIRES PM ATTENTION Why would attention be needed for a positive number? What if the schedule was over estimated? Are we using our resources efficiently? REQUIRES PM ATTENTION Why would attention be needed for a positive number? What if the schedule was over estimated? Are we using our resources efficiently?

Earned Value Terminology Steps to Success
Controlling Performance Indices
Term Interpretation
(SPI) Schedule Performance Index Calculates a ratio of the value of what was accomplished (EV) versus what was budgeted to accomplish it (PV), up to the status date. We are (only) progressing at __ of the rate originally planned
(CPI) Cost Performance Index Calculates a ratio of the value of what was accomplished (EV) versus what was actually spent to accomplish it (AC), up to the status date. Indicates if the cumulative actual costs during the assessed period are higher or lower than budgeted for the work completed. Single most important EV calculation We are getting ___ out of every 1 spent

(SPI) Schedule Performance Index (EV / PV) On schedule Poor Performance If SPI is less than 1.0 than less work was completed on your schedule than what was planned Good Performance If SPI is greater than 1.0 than your work accomplished was more than planned Work done out of sequence can lead a team to believe the project is ahead of schedule when it is not
(CPI) Cost Performance Index (EV / AC) On budget Poor Performance If CPI is less than 1.0 than you are over budget. Spending is more than planned for the work accomplished Good Performance If CPI is greater than 1.0 than you are under budget. Spending is Less than planned for the work accomplished
If your project is more than 20 complete, the CPI stabilizes. In other words, if you are overrunning at 20, you will be overrunning at completion. Furthermore, the overrun at completion will be greater than the overrun to date! Source research on 700 DOD contracts If your project is more than 20 complete, the CPI stabilizes.

Calculation Example
  • You have a project to build a new fence.
  • Fence is four sided (all sides are equal)
  • Each side is to take one day to build
  • Each side is budgeted for US 1,000
  • The sides are planned to be completed
    sequentially (one after the other)
  • Today is end of day three
  • Using the project status chart below, calculate
    EV, etc. When completed, check your answers on
    the answer sheet on the following page.

Task Day 1 Day 2 DAY 3 Day 4 Status
Side 1 S---F Complete, Spent 1,000
Side 2 S---PF ---F Complete, Spent 1,200
Side 3 PSS--PF Half Done, spent 600
Side 4 PS----PF Not Started

Controlling Step 8 Monitor EV Performance
Against Baseline (Control Step)
  • Variance analysis should address
  • Separate discussion of CV, SV (current and cum)
    and VAC
  • Clear description of reason for variance
  • Quantity variances (e.g., price vs. usage)
  • Be specific, not general
  • Corrective action
  • Technical, schedule, and cost impacts
  • Impact to estimate at completion
  • What is a significant variance?
  • variance (e.g., gt10)
  • variance (e.g., gt50,000)
  • Critical path element
  • Risk/complexity
  • impact to other elements
  • Top 10, Top 20, etc.
  • Owner

Earned Value Framework Steps to Success
Controlling Step 8 Monitor EV Performance
Against Baseline (Control Step)
  • Corrective Action- How to bring the task back in
    line
  • Crashing
  • Goal Gain the greatest amount of schedule
    compression with the least amount of cost
  • Looks at cost and schedule tradeoffs
  • Add Resources to the tasks in the critical path
    (internal or external)
  • Reduce project scope
  • Review changing the sequence of tasks
  • Often causes costs to increase
  • Which is the most important of the triple
    constraints to your stakeholders? (Cost,
    Schedule, Quality)
  • Fast Tracking
  • Starting two tasks at the same time that were
    previously scheduled to start sequentially
  • Can increase risk and might cause the project
    team to rework tasks
  • Develop a process to Reuse code This actually
    can reduce defect risk
  • Example We are six months into a million dollar
    project.
  • CPI 1.2 (we are getting 1.2 dollars for every
    dollar spent
  • SPI .89 (we are progressing only at 89 of what
    was planned)
  • What can be done?
  • Replace a more expensive member from the project
    team? (This would improve cost not schedule and
    add risk)
  • Bring in an additional programmer to work on the
    next two tasks. (Most effective choice)

40
Earned Value Framework Steps to Success
Controlling Step 9 Forecast Final Required
Costs
  • This step is in place to forecast the final
    required costs based on actual performance
  • Keep management apprised so corrective action can
    take place
  • Actual performance results are sunk costs. These
    are unrecoverable
  • Any improvements in performance must come from
    future work.
  • EAC indicates where the cost is heading
  • Earned value provides the capability to quickly
    and independently forecast total funds required
    to complete the project (ETC)
  • ETC is a forecast for completing the total
    project.
  • Considers the performance to date plus future
    estimates
  • Variance Reporting

Costs

(EAC) Estimate at Completion A. BAC / CPI AC ETC AC BAC - EV AC (BAC EV) / CPI Gives us an idea of final costs of a project. It takes into account the original budget (BAC). The earned value and the cost performance index of the already complete work. As of now, how much do we expect the total project to cost? ____. Formulas A. Used if no variances from the BAC have occurred or you will continue at the same rate of spending B. Used when the original estimate assumptions were fundamentally flawed or no longer relevant due to a change in conditions Requires PM to perform bottom up evaluation of Estimate to Complete Example Complete change in in environmental regulations creates a need for a different design than was scoped. Need rebaseline. C. Used when current variances are seen as atypical and the expectation is that similar variances will not occur in the future. Actual to date plus remaining budget modified by performance. D. Used when current variances are seen as typical of future variances Most respected, since cumulative variances are indicative of future variances
(ETC) Estimate to Complete EAC - AC From this point on, how much MORE do we expect it to cost to finish the project? An estimated cost to complete the remaining work on the project .

Earned Value Framework Steps to Success
Controlling Step 10 Manage Scope Through Change
Control
  • Integrated Change Control
  • Without a CC process performance baselines become
    invalid
  • Changes and new work due to issue management
    should be added to the schedule.
  • All change requests must be addressed quickly
  • Accept or reject by Change Control Board,
    Steering Committee or Sponsor
  • PMs should have authority to say no to changes
  • All changes should be documented
  • No Gold Plating!
  • Single most important factor to a sound EVM
    process and implementation

Earned Value Benefits
51
Earned Value Benefits
  • Provides managers with information at a
    practical level of summarization
  • Alerts PMs to potential schedule and cost risks
    early
  • Provides a documented project performance trail
  • Communicates project status
  • Tracks and monitors discrete project metrics
  • Relates time-phased budgets to specific contract
    tasks
  • Provides comparisons between planned and actual
    work
  • Provides accurate and reliable readings of cost
    and schedule performance
  • Actual performance at the 15 complete point can
    be used to predict final performance.
  • The schedule performance index (SPI) is useful in
    assessing how much work has been accomplished.
  • The CPI index provides a statistical basis for a
    best case final estimate.
  • The CPI and SPI indices may be combined to
    statistically forecast the most likely final
    estimate.

Earned Value Key Lessons Learned
53
Earned Value Key Lessons Learned
Lesson Attributed To Corrective Action
1 Schedule Compression incurs additional project cost Work cannot be scheduled and resourced in an optimal fashion Schedule compression almost always results in inefficiencies due to resource loading and reword
2 Education and buy-in are crucial Through time not just to start Lack of Senior Level Commitment Executives Project Managers Staff
3 WBS Quality / Reliability Plan the work carefully and accurately WBS Quality not maintained All parties buy in to the WBS WBS is simple - composed of measurable, deliverable pieces Risk-adjusted SPI/CPI
4 Sustenance Perceived Complexity Keep Process Simple and Tool Supported See 2
5 No variance reports / dashboards No policy in place or no standard Weekly high level metrics, Monthly Dashboard reporting with full EV Graphs and text Period/period compare
6 Manage by Exception Too much management will scare your PMs Micro Management Manage by exception. Focus on significant variances to the plan. Apply timely corrective actions.
7 Tracking conducted inconsistently. PM Discipline Track Track Track No Pain NO Gain
8 Time for data measurement, input, and manipulation can be considerable. Growing Pains Plan ahead Provide amble PM time to create and research results

Earned Value Limitations
55
Earned Value Limitations
  • Traditional EV is not intended for non-discrete
    (continuous) effort.
  • When a plan contains a significant portion of LOE
    intermixed with discrete effort, EVM results will
    be contaminated
  • The use of EVM presumes that stakeholders care
    about measuring progress objectively.
  • Quantifying/measuring work progress can be
    difficult.
  • Time required for data measurement, input, and
    manipulation can be considerable.
  • EVM requires thorough and accurate planning of
    cost and schedule to be effective.
  • Future performance is being forecast based on
    past performance (so if your data is bad, so is
    your forecast)
  • Earned Value does not measure quality
  • EVM is designed to ensure that the future
    predicted by EVM does not materialize as it
    encourages corrective action

56
Earned Value Dos and Don'ts
57
Earned Value Dos and Don'tsDos
  • Take the necessary building steps seriously
  • Integrate the scope of work, schedules, and costs
    using a WBS.
  • Train your stakeholders. It is critical they can
    understand the variance reports
  • Document all performance metrics and thresholds
    in the Project Plan (Performance Plan)
  • Determine how you will measure your tasks
    (discrete options)
  • Assess variances early No later than 15 in
  • ..Highest Potential for Cost / Schedule
    Recovery..
  • Make sure the bad news is heard
  • Take corrective action
  • Staff changes?
  • Mid-term evaluation of work
  • Crashing
  • Fast Tracking

58
Earned Value Dos and Don'tsDos
  • Request and monitor that staff enters actual
    hours each week
  • Provide PMs with a reliable labor and overhead
    rates for each resource.
  • Without the rate CPI does not mean much
  • Have policies in place for rebaselining
  • Keep your original baseline in tact and always
    measure against it
  • If for no other reason, it keeps historical
    estimates in place
  • Re-plan as necessary
  • Budget increase?
  • Scope change?
  • Schedule change?
  • Create a weekly or Monthly Variance Report
  • Use standard templates for reporting
  • Helps with the learning curve
  • Helps to compare or aggregate data across
    projects
  • Institute Standard Reporting Cycles

59
Earned Value Dos and Don'tsDos
  • Perform scheduling and WBS creating at the same
    time.
  • There is a documented order defined in the PMBOK
  • Most Common Error
  • Dont set up your project with level of effort
    planning.
  • Creating one task (i.e. design) and allocating a
    certain number of people to it over a fixed
    amount of time.
  • Earned value will not be possible. The only
    measurement possible will be cash flow
  • Leave planning until your financials and WBS are
    integrated through Cost Control
  • Cost account structures and the level of detail
    to be tracked must support the earned value
    management system.
  • Each cost account should have a unique identifier
    to enable an accurate calculation of the actual
    cost of work performed (ACWP).
  • Manage at only the contract / engagement level
  • Rarely are projects managed at the WBS
    Deliverable Level EV Loses Control

60
Earned Value Dos and Don'tsDon'ts
  • Focus solely on schedules. This is the typical
    PM Mindset by Business Culture. PMs
  • Are focused on Schedules --NOT Costs
  • Manage at the contract level vs the WBS
    Deliverable Level
  • Leave real Billing Rates out of the WBS
  • Competition Sensitive Data
  • Artificial Blended Rates
  • Fixed Price, So Why Bother
  • The 1.00 per hour fix
  • Let your tasks or milestones get too large in
    duration, cost and scope
  • Could impact PMs ability to identify variances
    at a level that can be corrected
  • Include multiple individuals on the same task
    whenever possible
  • Helps identify root cause of variances easier
  • Forget Success factors
  • A full WBS is required (all scope)
  • Beware of GIGO Garbage-in, garbage-out
  • No Gold Plating!
  • If you know there is a significant variance dont
    wait until you create the monthly report to begin
    corrective action planning
  • Assume adding a resource or adding paid overtime
    will fix the schedule variance most likely
    will create a CPI issue. Cover this with
    stakeholders early.

61
Why do we need early warning
Course corrections are easier when you have time
to make small adjustments Its too late when
youre this close to the iceberg!
