Development of an Earned Value Cost/Schedule System
Time-Phase Baseline Plan
Corrects the failure of most monitoring systems to connect a project’s actual performance to its schedule and forecast budget.
Systems that measure only cost variances do not identify resource and project cost problems associated with falling behind or progressing ahead of schedule.
Earned Value Cost/Schedule System
An integrated project management system based on the earned value concept that uses a time-phased budget baseline to compare actual and planned schedule and costs

Glossary of Terms
TABLE 13.1
| EV | Earned value for a task is simply the percent complete times its original budget. Stated differently, EV is the percent of the original budget that has been earned by actual work completed. [BCWP—budgeted cost of the work performed]. |
| PV | The planned time-phased baseline of the value of the work scheduled. An approved cost estimate of the resources scheduled in a time-phased cumulative baseline [BCWS—budgeted cost of the work scheduled]. |
| AC | Actual cost of the work completed. The sum of the costs incurred in accomplishing work. [ACWP—actual cost of the work performed]. |
| CV | Cost variance is the difference between the earned value and the actual costs for the work completed to date where CV = EV – AC. |
| SV | Schedule variance is the difference between the earned value and the baseline line to date where SV = EV – PV. |
| BAC | Budgeted cost at completion. Total budgeted cost of the baseline or project cost accounts. |
| EAC | Estimated cost at completion. |
| ETC | Estimated cost to complete remaining work. |
| VAC | Cost variance at completion. VAC indicates expected actual over- or under-run cost at completion. |

Development of Project Baselines (cont’d)
Rules for Placing Costs in Baselines
Costs are placed exactly as they are expected to be “earned” in order to track them to their point of origin.
Percent Complete Rule
Costs are periodically assigned to a baseline as units of work are completed over the duration of a work package.

Methods of Variance Analysis
Comparing Earned Value with:
The expected schedule value
The actual costs
Assessing Status of a Project
Required three data elements
Planned cost of the work scheduled (PV)
Budgeted cost of the work completed (EV)
Actual cost of the work completed (AC)
Calculate schedule and cost variances
A positive variance indicates a desirable condition, while a negative variance suggests problems or changes that have taken place.

Methods of Variance Analysis
Cost Variance (CV)
Indicates if the work accomplished costs more or less than was planned at any point in the project.
Schedule Variance (SV)
Presents an overall assessment in dollar terms of the progress of all work packages in the project scheduled to date.

Developing A Status Report:A Hypothetical Example
Assumptions
Each cost account has only one work package, and each cost account will be represented as an activity on the network.
The project network early start times will serve as the basis for assigning the baseline values.
From the moment work an activity begins, some actual costs will be incurred each period until the activity is completed.

Indexes to Monitor Progress
Performance Indexes
Cost Performance Index (CPI) = EV/AC
Measures the cost efficiency of work accomplished to date.
Scheduling Performance Index (SPI) = EV/PV
Measures scheduling efficiency to date.
Percent Complete Indexes
Indicate how much of the work accomplished represents of the total budgeted (BAC) and actual (AC) dollars to date.
Percent Complete Index Budgeted Costs (PCIB) = EV/BAC
Percent Complete Index Actual Costs (PCIC) = AC/EAC
Management Reserve Index (MRI) = CV/MR
Reflects the amount of Management Reserve (MR) that has been absorbed by cost over-runs.
Is popular in the construction industry.

Additional Earned Value Rules
Rules applied to short-duration activities and/or small-cost activities
0/100 percent rule
Assumes 100% of budget credit is earned at once and only when the work is completed.
50/50 rule
Allows for 50% of the value of the work package budget to be earned when it is started and 50% to be earned when the package is completed.
Ruled used gates before the total budgeted value of an activity can be claimed
Percent complete with weighted monitoring gates
Uses subjective estimated percent complete in combination with hard, tangible monitoring points.

Forecasting Final Project Cost
Methods used to revise estimates of future project costs:
Revised estimated cost at completion (EACre)
Allows experts in the field to change original baseline durations and costs because new information tells them the original estimates are not accurate.
Forecasting cost at completion (EACf)
Uses actual costs-to-date plus an efficiency index to project final costs in large projects where the original budget is unreliable.
